From the Doctor’s Desk: Salivary Hormone Testing Backed by Science

Saliva testing for hormones first appeared in the medical research literature in the early 1980′s. Salivary testing is becoming the testing method of choice for many reasons including: saliva testing seasons

  1. Saliva testing evaluates the “free” (active) hormone levels. A hormone has to be unbound to elicit a physiologic action. Saliva testing looks at the active hormone inside the cell, at the site of action. Saliva testing has been validated as a testing method for measuring the hormones cortisolestradiolprogesteroneDHEA, and testosterone to name a few.
  2. Saliva testing requires no needles.
  3. Saliva testing has been shown to be well validated and superior than blood, with sensitivities and specificities exceeding 100% and 97.4% respectively.  Other than perfection, you can’t get much better than that.
  4. According to the National Institute for Health, saliva testing is useful in “detecting various cancers, heart disease, diabetes, periodontal disease…”
  5. Saliva testing is also useful in disease evaluation. Saliva testing of cortisol has been recommended as the first-line test for Cushing’s syndrome due to “high diagnostic accuracy.”

Testing hormones through saliva is backed by science. But don’t take my word for it. In fact, it’s well supported in medical literature and is the right thing to do. Below are links to several abstracts regarding salivary hormone testing. Read them for yourself and learn about the science behind this form of hormone testing.

These articles are published in well-respected journals; and if you notice, they are not recent. Salivary testing of hormones has been well published in the medical literature for some time now.

Here are a few quotes from these studies:

  • “…salivary cortisol may be used as an alternative parameter in dynamic endocrine tests.”
  • “…assessment of ovarian function…can be performed precisely with the saliva estradiol assay.”
  • “…saliva collection has provided the medical and research community with an excellent medium for the monitoring of plasma steroid levels.”

Nowhere else in medicine do we blindly treat people without assessing a baseline and post treatment level(s). Balance is the key; not one individual hormone. Unfortunately, the medical field is very slow to learn and change.

New Perspectives On Hormone Balance Ahead

DecNewsletterHeaderFARPerspective. It affects everything. Take, for example, the beauty of the earth. Some might look at the magnificence of the earth and think of Darwinian theory. But as I stand in my back yard, I am amazed by God’s creation. When I look out of the window on my many plane flights, I am amazed by God’s creation. And when I see the perspective from space as seen by astronauts, I am still amazed at God’s creation.

Perspective colors the way we see everything around us. For those, like myself, who believe in the God of creation, I view the world a certain way. And for those who choose to believe otherwise, they view the world a certain way.

Perspective is an important part of the medical world as well. As technology improves, the amount of information available to me as a physician changes the way I treat my patients because I now have more data than I’ve had in the past helping me make a better decision.

So, let’s talk about how perspective is an important part of evaluating hormones! (And you thought the only important perspective about hot flashes was “where’s the air conditioner”!)

If men were only about testosterone and women were only about estrogen, life would be easy and all would be symptom free. Unfortunately, that is, in a nutshell,  the current perspective on treatment of hormone imbalance issues. It is not, however, an accurate perspective based on physiology. Just watch an hour of TV in the evening. The pharmaceutical companies are inundating us with ads about testosterone creams and the like. Regardless of clever marketing, looking at the reality of physiology based on the latest testing methods reveals that hormones are a lot more complicated than treating the level of just one hormone.

When it comes to hormones, there are four important components necessary for physiologic function and symptom-free living.

  1. Hormone levels need to be in the “normal” range. We don’t need the respective hormone levels too high or too low.
  2. Hormones need to be balanced. This is where many in the medical field get it wrong since all hormones work together to communicate to the body.
  3. Your body needs to effectively use the hormones present. Hormone metabolism is a key element in evaluating hormones in the body.
  4. Hormone receptors must appropriately respond to the signal sent by the hormone to your body.

The past (and current) perspective of the medical community is that the absolute levels of individual hormones are what is important and little attention is given to balance between hormones. Very little attention is given to the balance between hormones. For example, women, post-hysterectomy, are prescribed estrogen only. But we know that prior to the hysterectomy, all hormones are needed for a normal, functioning cycle, not just estrogen alone.

Some of the risks associated with estrogen therapy pertains to how the individual metabolizes or detoxifies the estrogen. Hormone metabolism can be affected by internal factors like genetic variations, or SNPs (single nucleotide polymorphisms), located in the detoxification pathways. These are small genetic coding errors. Hormone metabolism can also be affected by external factors such as magnesium and zinc, co-factors in those same internal detoxification pathways of hormone production and metabolism. Just the presence of the detoxification pathways does not a functional detoxification pathway make.

Finally, and the purpose of this post, are the receptors. Hormone receptors determine how the hormone’s signal to the body is then interpreted. Here’s an analogy to help you understand hormone receptors. I have four beautiful children. As with any parent, getting them to clean their room is an ongoing battle. The signal I give them is a verbal instruction such as “Kids, it’s time to get your rooms cleaned.” How that signal is interpreted is quite different. That signal may be interpreted differently based on the environment or pre-existing conditions. If my children are in one of their “moods” (side note: all four of my kids are redheads), then they may just not clean their rooms out of defiance. There is a reason we call the youngest one “the spicy tomato.”

All this to illustrate one important fact — how the signal is interpreted is just as important as the signal that is to be interpreted.

Scientifically speaking, hormone receptors are defined as “a large family of ligand-activated nuclear transcription regulators, which are characterized by organization into different functional domains and are conserved, to differing degrees, between species and family members.”

Was that as clear as mud? In plain English, hormone receptors are how the external signal, hormones, provide to the internal genome a message to turn genes on or off. There is also non-genomic signaling, but a large portion of signaling is actually done with your DNA. This is what hormones do — interact and turn on and off the expression of your DNA. Pretty amazing, huh? And you just thought hormones floated through your blood causing hot flashes in women or ED in men. That is the way most, including physicians, see hormones. However, that just couldn’t be more further from the truth. There’s so much more to it than that.

 Hormone receptors are being used in the medical vocabulary today. If you know someone with breast cancer, you might be familiar with the term ER/PR positive or negative. This is in reference to estrogen receptors and progesterone receptors. This evaluation occurs from an actual tissue sample from the tumor itself and allows the medical team to determine the best course of action for that particular individual. In ER/ PR positive tumors, hormone therapy is used in contrast with ER/PR negative tumors where no hormone therapy is used.

The medical community is addressing the realities of hormone receptors and the role they play in disease. But what about those individuals with hormone imbalance symptoms like hot flashes or erectile dysfunction? Stay tuned. This testing hasn’t made it to the clinical setting yet, but animal testing holds great promise in helping to complete the full picture and improve the perspective that we have on hormones and all their related issues and factors.

Hormone receptors are my current area of research, and I’m writing articles on estrogen, progesterone, and androgen (male hormones) receptors as part of that research. Visit the Seasons Wellness Clinic blog often in the upcoming months so that YOU can become more educated on the body’s communication system — hormone and their receptors.

Navigate Your Health Journey With Good Reading

 

Because Tennessee ranks 39th in overall health of its citizens [according to America’s Health Rankings], we are passionate about educating the community on how to improve their health. I spend time daily reviewing the latest findings from scientific studies related to health and wellness topics to insure that Seasons is always offering the latest and best solutions for pursuing wellness.

Contrary to the belief of many, good health is not something that can be mandated from government or given to you by a physician. Health is a personal journey acheived only through education and self-awareness. At Seasons, our goal is to provide you with the resources you need to improve the health of you and your family.

Here are five books that are easy reads and are rich in good information for your health journey.

Inflammation Nation by Floyd H. Chilton, PhD

Inflammation Nation was written by Dr. Floyd H. Chilton in 2005. While the book goes back a few years, it is still incredibly relevant. Inflammation is one of the primary problems/obstacles to health today. Inflammation, in the short term, is a necessary part of the healing process. When you are cut, the “inflammation” present through redness, pain, and swelling works to protect the body from invasion and to start the process of healing. But the inflammation subsides quickly. However, in some, inflammation rages on and promotes disease.

It would make sense that if something, certain types of food for example, were causing inflammation in our body and ultimately leading to disease, we would want to eliminate the problem, reduce the inflammation and prevent disease, right? Dr. Chilton discusses the immune system and how our diet affects it. The old adage “you are what you eat” definitely applies here.

Inflammation Nation is an easy read and provides many easy recommendations to incorporate into your daily life.

The Wheat Belly by William Davis

The Wheat Belly is written by William Davis. Very rarely do I encounter clients that have not read or heard of this book. This book touches on a growing problem in America and the world today – an adulterated food supply. Not food supply that is adulterated with parasites or bacteria, but that is adulterated from within. What does that mean? In The Wheat Belly, Dr. Davis touches on the fact that the wheat of today is not the wheat our parents ate. Not only is the nutritional value present in wheat lost, but the genetic modification is likely contributing to inflammatory problems.

The problem with genetically modified foods (GMO) is we have limited knowledge of their impact on the body. And the federal government and its agencies have never done a good job of investigating these items before rushing them to market. Just look at the history of environmental toxins such as phthalates, parabenes, and other volatile solvents, all brought to market labeled as safe only to be removed from the market when revealed as seriously dangerous toxins.

This book is also a very easy read and provides easy dietary recommendations to immediately bring positive changes to your health.

What Your Doctor May Not Tell You About Breast Cancer by John R. Lee, M.D., David Zava, Ph.D., and Virginia Hopkins

This was the very first integrative medicine book I read in 2006. This book goes back to several founding people in the integrative medicine movement like Dr. John Lee, an oncologist who led the movement in bioidentical hormones and saliva testing. Dr. Lee was ostracized by the medical community, but his commitment to his patients and to true scientific evidence is an example for all to follow. In fact, Dr. Zava believed in this movement so much that he started a saliva-testing company.

As it relates to breast cancer, there are few more published than Dr. Lee and Dr. Zava. I have met Dr. Zava personally on several occasions, and there are few that I would put above his in both scientific integrity and commitment to true science.

This book lays out a different approach to breast cancer, one focusing on prevention instead of early detection. Traditional medicine focuses instead on early detection and cancer treatment. Don’t get me wrong. We need that, but true prevention is where we should first focus.

The book is deep at points, but is a good discussion of biochemistry and physiology as it relates to breast cancer. Its focus on more natural ways to prevent breast cancer is based on the scientific research. The book clears up much of the misinformation about hormones and breast cancer and equips the reader to be advocate in the prevention of breast cancer.

The book’s authors were unafraid to take on traditional medicine, but do so with a good foundation of science.

The Blood Sugar Solution by Dr. Mark Hyman

Dr. Hyman is a great proponent of wellness and a pillar in the integrative medicine community. This book, published earlier this year, is an easy weekend read with numerous tools to incorporate into everyday life. The focus of this book is nutrition, sugar, in particular.

Obesity is at epidemic levels in the United States. According to CDC data, 13 states now have an obesity rate greater than 30 percent, while in the year 2000, NO states reported obesity rates greater than 30 percent. This book takes the major culprit head-on: diet.

The Blood Sugar Solution delves into diet, insulin, insulin resistance, and a host of other factors contribute to poor health. The book provides many tools to succeed in the “battle of the bulge,” and even includes recipes to help you succeed in your personal health journey.

What Your Doctor May NOT Tell You About Hypertension by Dr. Mark Houston

If you ever have the chance to meet Dr. Mark Houston, you will surely be impressed. Mark Houston, M.D., is Associate Clinical Professor of Medicine at Vanderbilt University School of Medicine, Director of the Hypertension Institute and Vascular Biology, and Medical Director of the Division of Human Nutrition at Saint Thomas Medical Group, Saint Thomas Hospital in Nashville, Tennessee.

While his list of credentials are a mouth full, to hear him speak will fill your ear! As a cardiologist focused on an integrative approach, there are few that speak so eloquently on the deep biochemical disease found in cardiovascular disease.

While the subject matter might sound intimidating, this book, is a very easy read and focuses on the underlying dynamics of hypertension and associated complications. Dr. Houston defines the problem and lays out solutions with his wildly successful program for treatment of hypertension using an integrative medicine approach.

Dr. Houston also provides a health discussion of hypertension medications, when needed, and the mode of action and side effects of each. This a definite must-read for anyone on hypertension medications. You might just become more informed than your own physician!

While this book is a self-help guide to natural treatments of hypertension, it is based on sound science and the approach has been extremely successful. This book is also heavily referenced, allowing you the option of pursuing deeper learning if desired. This book removes every obstacle to reducing hypertension except you. It’s your job to act on what you read.

The Naturally Healthy Woman: Whole Health for the Whole Woman by Shonda Parker

Yes, I know I said five and this is number six! But this is a very good manual for women and their health. As an OB/Gyn, my first passion was women’s health. The author, Shonda Parker, whom I have met, is a true blessing to know. There are few who have a passion for health that exceeds hers, and she has an ever better spirit. Shonda is a nurse midwife, has authored many books, and speaks nationally on health and other related topics. This book highlights many of the health issues facing women today, and I predict that the edges of this book will become tethered due to your repetitive use after reading it.

As a nurse midwife, the author’s first passion is pregnancy. This book begins by touching and then builds into many other health issues affecting women. The author provides many natural remedies at the end of each section for the different health issues discussed. The book not only provides natural therapies for the mother/wife, but also for the rest of the household.

Every pathway to health is different. Every journey to wellness is unique. At Seasons, our desire for wellness for all begins with education and knowledge for you. I hope that these books will become additions to your library and provide you with the knowledge you need in your personal journey toward wellness.

Evaluating Hormones Requires More Than Just a Blood Test

Dr. Nathan Goodyear

“I just don’t feel right.” These are frequently the first words I hear a patient say. “I’m so hormonal…I know I’m not balanced. I’m tired, cranky….” and so goes the list of symptoms, all of which indicate hormone imbalance.

It’s amazing to me that most patients know intuitively that they don’t feel good and it has something to do with hormones, but they’ve had a blood test by their physician and everything checked out “okay.” That blood test, however, didn’t change the fact that they still feel terrible.

There is a lot of debate these days regarding the different methods of evaluating hormones: blood, saliva, and urine (oh my). In a few short weeks, school will start. So to get back in the swing of things, today school is “in session” and a science lesson is the order of the day. The topic? How are hormones evaluated and which is the best test for you?

Hormone Delivery and FedEx?

Understanding complicated topics is often made simple with a great analogy. My good friend, Dr. Eldred Taylor, uses the analogy of FedEx trucks to explain hormones and their delivery to the cells of the body. And I especially like this analogy because my dad has been a pilot for FedEx for many years!

FedEx trucks are everywhere during the month of December. It wouldn’t be unusual for a lot of trucks to pass your house during that month. But, if the FedEx trucks don’t stop at your house, it doesn’t really matter how many trucks have driven by your house or how many packages each truck contained. The fact remains that none stopped for delivery. It only takes one FedEx truck to stop at your house and the Christmas tree is full.

I’ll take it one step further. The day after Christmas, the boxes and wrapping paper are piled up at the road-side for pickup. You might comment as you drive by your neighbor’s house “It looks like the Jones’ had a good Christmas” based on the curbside aftermath. You can even make out what the gifts were based on the leftover boxes and debris on the curb.

What does it all mean? The FedEx trucks symbolize hormones in transport in the blood. It doesn’t matter how many hormones are transported through the blood (FedEx trucks), they are inactive (the truck didn’t stop at your house). When the FedEx truck stops at your house, it symbolizes when hormones are dropped off for action inside the cell. One truck can drop off 100 packages or 100 trucks can drive by, dropping off no packages. Finally, the post-Christmas driveway debris represents the hormones after the body has broken them down into metabolites.

Hormones can be evaluated through three different testing methods: blood, saliva and urine. Blood testing evaluates the number of FedEx trucks in your neighborhood. Saliva testing evaluates the number of packages delivered at your house. And urine testing evaluates the post-Christmas driveway debris to identify what packages were delivered and opened.

So what does the science say about the hormone testing methods of blood, saliva, and urine?

Blood Testing

Testing hormones present in the blood has been used to develop the current reference norms that we use in the diagnosis and management of many diseases. It has been around a long time. This kind of testing is effective in the disease model of medicine. However, in the wellness model of medicine, we are looking for dysfunction, not just disease. And this is where the effectiveness of blood testing breaks down.  By identifying physiologic dysfunction, we hope to prevent disease. It is the move into true preventative medicine, not just early detection, the wellness model of medicine has found the blood testing of hormones to be lacking.

There are three main problems with blood hormone testing.

  1. First, is the whole idea of a needle. If we can evaluate hormone levels without puncturing the skin, then we should.
  2. Blood testing evaluates hormones in transport. This is typically reported as “total” hormone levels and the “free” active levels are calculated. Transported hormones are inactive. Hormones in the blood are bound to proteins (estimated at 95-99%) and inactive. Going back to the FedEx truck analogy, blood testing tells me how many FedEx trucks there are and how many packages they have to deliver. But it doesn’t tell me how many packages were delivered at your house. And that’s a very important piece of information. Are your hormones coming or going? And is your body utilizing the hormones you have?
  3. It is not the most accurate form of testing. Saliva testing is proving to be superior to blood testing for measuring hormones (see Saliva below).

Urine Testing

The use of urine to evaluate cortisol has been present for awhile.  And this is a valid method to test cortisol, one of your body’s hormones. The problem with this form of testing is that most people don’t want to carry a jug around collecting urine for 24 hours.

Currently, the interesting research on urinary testing of hormones is in the measurement of metabolites. Think back to our analogy. Urinary testing is best used for looking at the curbside debris to see what presents were opened at Christmas. By measuring metabolites, we can see how effectively your body is metabolizing hormones. If your body is ineffectively metabolizing hormones, the resulting symptoms and conditions can include Chronic Fatigue Syndrome, obesity, fatigue, and increased breast cancer and prostate cancer risk to name a few. These issues are all treatable at Seasons Wellness Clinic with a customized wellness plan based on your test results.

Saliva Testing

Saliva testing for hormones first appeared in the medical research literature in the early 1980′s. Saliva is becoming the testing method of choice for many different reasons. Going back to our analogy, saliva testing measures the number of packages that are delivered by the FedEx truck at your house.

  1. Saliva testing evaluates the “free” (active) hormone levels. A hormone has to be unbound to elicit a physiologic action. Saliva testing looks at the active hormone inside the cell, at the site of action. Saliva testing has been validated as a testing method for measuring the hormones cortisolestradiolprogesteroneDHEA, and testosterone to name a few.
  2. Second, saliva testing requires no needles.
  3. Saliva testing has been shown to be well validated and superior than blood, with sensitivities and specificities exceeding 100% and 97.4% respectively.  Other than perfection, you can’t get much better than that.
  4. According to the National Institute for Health, saliva testing is useful in “detecting various cancers, heart disease, diabetes, periodontal disease…”
  5. Saliva testing is also useful in disease evaluation. Saliva testing of cortisol has been recommended as the first-line test for Cushing’s syndrome due to “high diagnostic accuracy.”

Saliva testing gives me the information I need to diagnose what’s going in your body. And while that is my opinion based on my training, it’s also opinion based on scientific fact according to hundreds of research articles (see links to additional articles below). Saliva testing is now considered the “gold standard” for hormone evaluation.

Today you have learned about the three methods physicians use for evaluating hormones: blood, saliva and urine. You’ve also learned that each test is useful for measuring different things. We can evaluate hormones many different ways at Seasons and determine not only the amounts of a specific hormone in your body, but also how effectively your body is actually using (or not using) those hormones with saliva and urinary testing.

Most important is the clinical relevance of each test. Testing the hormones at the site of action provides the best physiologic approach (saliva testing). Testing the hormone metabolites provides the next best approach (urine testing). Through the evaluation of the body’s metabolism of hormones, the physiologic mechanisms of how the body removes hormones can be evaluated.  The evaluation of hormones in transit (blood testing) provides the least physiologic assessment.

While each test provides an appropriate measure, the question is, does that measure provide insight into physiologic dysfunction? And, can an appropriate therapeutic intervention be undertaken to effect a change? At Seasons, we provide answers using those test results, creating a customized wellness plan that will put you on the road to a life with more energy, balance, and, ultimately, happiness.

Cheers to the pursuit of wellness.

Man vs. Estrogen: It’s Not Just A Woman Thing!

Nathan Goodyear, M.D.

Testosterone is the defining hormone of a man. Estrogen is the defining hormone of a woman.

So when we talk about estrogen, it’s that word men whisper in secret when the women in their lives seem a little hormonal, right? When people find out that my wife and I have 3 daughters, the resulting comment is usually, “Wow, that’s a lot of estrogen in your household!” (Thankfully, I have a son, too, who helps balance the estrogen to testosterone ratio at our house!)

I’m sorry to burst your bubble, guys, but estrogen is not exclusive to women. We make estrogen, too. In fact, some of us make a LOT of estrogen. Too much, in fact. And it creates some serious problems.

But before we talk about estrogen, we need to talk about testosterone. Testosterone levels in American men are at an all-time low! There are four major reasons for that: stress, weight, endogenous estrogens, and xenoestrogens. In this post, I’ll address three of those – stress, weight, and endogenous estrogen.

So let’s get started learning four important facts about testosterone, estrogen, and men!

What problems do high estrogen levels create in men?

1. High estrogen = low testosterone. One of the primary causes of low testosterone is a high estrogen level. Estrogens can be endogenous (produced by your body) or exogenous (from the environment, also known as xenoestrogens). Estradiol and Estrone (two of the three kinds of estrogen produced by your body) feed back to the hypothalamus and pituitary and shut off testosterone production.

2. High estrogen = inflammation. Not only do high estrogen levels decrease testosterone in men, they also increase inflammation. And this is VERY significant. Inflammation, just like stress, is a biochemical process.

inflammation & HormonesInflammation is the natural result of the immune system. Remember the last time you got a paper cut?  It was incredibly painful, probably red, warm and swollen, all cardinal symptoms of inflammation. Inflammation, in the right setting, is actually the body protecting itself.  However, when the immune system becomes imbalanced or chronically activated, the immune system causes damage through inflammation. For example, chronically activated immune cells in the brain (glial cells) play a pivotal role in the development of Alzheimer’s, Parkinson’s, and Multiple Sclerosis.

Inflammation is a SERIOUS issue. Chronic inflammation has been linked to many of the chronic diseases of aging: Type II Diabetes, obesity, hypertension, and cancer. In fact, a new term has been coined to describe inflammation arising from the gut which results in many of the above listed disease states - metabolic endotoxemia.

We’ve established that high estrogen levels are bad for men, shutting down testosterone production and causing chronic inflammation leading to disease.

What causes high estrogen levels in men?

1. High aromatase activity = high estrogen. First, high endogenous estrogen levels in men come from high aromatase activity.  Aromatase is the enzyme that converts androstenedione and testosterone into estrone and estradiol respectively. Aromatase is present in many different tissues. But in men aromatase is highly concentrated in that mid-life bulge.

Unfortunately, aromatase activity in men increases as we age due to stress, weight gain, and inflammation. None of us are going to get away from aging (it’s right there with death and taxes). And who do you know that has NO stress? (Remember, it is estimated that 90% of doctor visits are stress-related.) Typically, as we age we gain weight and have more inflammation.

That “age-related” tire around the mid-section is more than just unsightly. It is a hormone and inflammation-producing organ. Remember metabolic endotoxemia, the disease-producing state I mentioned earlier? Metabolic endotoxemia is inflammation arising from the GI system which causes obesity and then turns right around and produces inflammation. It’s a vicious cycle!  And guess what is concentrated in fat? If you guessed aromatase activity, then you are absolutely correct. Aromatase activity in men accounts for 80% of estrogen production.

Hormones are not just about numbers, but balance and metabolism as well (read my recent post on the topic).

2. Overdosage of testosterone = high estrogen. As mentioned earlier, testosterone levels in men are at an all-time low. And the mass solution for this problem with most physicians is to increase testosterone without evaluating or treating the underlying causes for low testosterone. Unfortunately, this complicates the entire low testosterone problem. Overdosage of testosterone increases estrogen production.

What?  You mean you can dose too high on testosterone? Yes, and most of the patients I see who are being treated with testosterone have been, in fact, overdosed.

In fact, at Seasons Wellness Clinic and Seasons of Farragut, we have seen many men must donate blood due to excess production of hemoglobin and hematocrit, a by-product of testosterone overdosage. A 20-22 year old male normally produces 5-10 mg daily of testosterone. It is during this age range that men are at their physical peak of testosterone production. For me, this was during my college football years.

Does it make sense for 40-and-up men currently taking testosterone, that they did not need to donate blood monthly during their peak years of natural testosterone production, but are currently required to donate blood regularly with their current regimen of testosterone?  Of course not. So, if you didn’t have to donate blood with your peak testosterone production in your 20′s, you shouldn’t have to donate with testosterone therapy in your 40′s and beyond either. Something is wrong here, right?

The starting dosage for one of the most highly-prescribed androgen gels is 1 gram dailyMen, we didn’t need 1 gram of testosterone in our early 20′s, and we don’t need it in our 30′s and beyond.

80% of a man’s testosterone occurs from aromatase activity, and aromatase activity increases as we age. So high doses of testosterone don’t make sense. Doctors are just throwing fuel on the fire with these massive doses. More is not better if it’s too much, even when it is something your body needs.

Then, there is the delivery of testosterone therapy. The body’s natural testosterone secretion follows a normal diurnal rhythm.  Testosterone is known to be greatest in early morning and lowest in the evening.  But with many prescribing testosterone therapy today, it is very common to get weekly testosterone shots or testosterone pellets. This method of delivery does NOT follow the body’s natural rhythm. The shots and pellets delivery method of testosterone produce supra physiologic (abnormal) peaks. If the purpose of hormone therapy is to return the body to normal levels, then that objective can never be reached with this type of testosterone therapy.

The effects of Testosterone to estrogen conversion in men and women are different. That’s certainly no surprise. In men, high aromatase activity and conversion of testosterone to estrogen has been linked to elevated CRPfibrinogen, and IL-6.

Are these important?  CRP is one of the best indicators of future cardiovascular disease/events (heart attacks and strokes), and is associated with metabolic syndrome. And yes, it is more predictive than even a high cholesterol level. Fibrinogen is another marker of inflammation that has been associated with cardiovascular disease and systemic inflammation. IL-6 is an inflammatory cytokine (immune signal) that has been implicated in increased aromatase activity (conversion of testosterone to estrogen) and at the same time is the result of increased testosterone to estrogen activity.

So, what’s the big deal? The studies are not 100% conclusive, but it is clear that inflammation increases the testosterone to estrogen conversion through increased aromatase activity. And the increased estrogen conversion is associated with increased inflammation in men. It’s a vicious cycle that will lead to disease states such as insulin resistance, hypertension, prostatitis, cardiovascular disease, autoimmune disease, and cancer, to name a few.

You may be thinking, “Is the testosterone I need leading me to disease?”

The answer is, “Yes, it sure can.” If your testosterone therapy includes prescription of supra physiologic levels of testosterone, lack of follow-up on hormone levels, and no effort to balance hormones and metabolism, then yes, it sure can.

Is there a safe and effective way to balance hormones, lower estrogen and increase testosterone for men?

Effectively administering hormone therapy requires the following:

  • A physician with extensive training in hormones and body biochemistry.
  • The best and most accurate testing possible to determine current hormone levels and to track hormone levels after therapy is administered.
  • Hormones that most closely replicate the natural ones produced in your body — bioidentical hormones.
  • A therapy plan with the objective of returning your body to normal, not super-charging the body with unnatural levels of testosterone or any other hormone.

At Seasons of Farragut, Nan Sprouse and I are fellowship-trained (or completing fellowship training) specifically in the areas of hormone therapy and wellness-based medicine.

Our patient experience begins with an initial consultation to evaluate symptoms and develop an evaluation plan.

The next step is testing. In the case of hormone imbalance, we evaluate hormones with state-of-the-art hormone testing via saliva, not just blood. As stated in a 2006 article, “plasma levels of estradiol do not necessarily reflect tissue-level activity.”  Saliva has been shown to reveal the active hormone inside the cell at the site of action.

After initial testing and a therapy program, hormone levels are re-evaluated to ensure the progression of treatment and necessary changes are made to the treatment program. Testing and follow-up are key to proper balance of hormones (read my recent post). At Seasons of Farragut, our approach to treatment and therapy is fully supported in the scientific research literature, and we’re happy to share that research with you if you’d like to educate yourself.

The way estrogens are metabolized plays an equally pivotol role in hormone risk and effect. At Seasons of Farragut, our system of testing, evaluating, and monitoring is the only way to ensure that testosterone therapy for men is raising the testosterone and DHT levels instead of all being converted to estrogen. Hormone therapy is safe, but for it to work effectively, it must be properly evaluated, dosed, followed, and re-evaluated.

If you have questions or comments, please post them below and I’ll respond as soon as possible. What is your experience with testosterone therapy? How has your physician tested and re-evaluated your therapy program?

The Top 3 Answers to the Question “Why Should I Take Hormones?”

Dr. Nathan Goodyear

Recently during a patient’s visit, we were reviewing her most recent OB/GYN appointment. Her physician asked why she was taking hormones. Unable to offer a technical explanation, she simply stated that she felt much better than she did before she began her treatment program.

While the basic question of WHY is a good question by her physician, we actually need to answer three questions.

  •  What are my individual hormone levels?
  •  Are my hormones in appropriate balance?
  •  Is my body metabolizing those hormones in the right way?

The answers to these three questions will answer the one question: “Why should a patient take hormones?”

What are my individual hormone levels?

Contrary to what most think, hormones are not just about individual numbers. Instead, hormones work collectively as a means of communication within the body. I am amazed at the answers I get when I ask postmenopausal women, “Does your body still have or need hormones?”

The answer is a resounding YES, but most people seem to think otherwise. The body must have hormones to survive. For example, those who suffer from Addison’s Disease have a life-threatening deficiency of cortisol (one of the body’s many hormones).

Far too often I hear the comment, “I’ve had a hysterectomy, so I don’t need progesterone.” The truth is having a hysterectomy does not eliminate your body’s use or need for hormones. It just means you are missing your uterus. Hysterectomy or not, millions of cells throughout the body have progesterone receptors and those cells could care less if you’ve had a hysterectomy or what your OB/GYN thinks about progesterone. [Insert laugh here!] These organ systems throughout the body have receptors for progesterone because they need progesterone.

The aforementioned patient’s hormone therapy included progesterone cream and DHEA capsules. Testing results showed her to be deficient in both progesterone and DHEA (read about how we test hormones at Seasons), and thus replacement was needed. In addition to test results, the patient’s clinical symptom history warranted the replacement of these hormones.

So why was DHEA included in her treatment program? Two reasons. The first is that her DHEA levels were low in her testing results. The second reason? This patient had Type II Diabetes and, after some additional testing, was found to have chronic inflammation throughout her body. DHEA has been shown to reduce inflammationimprove insulin function, and reduce obesity, all of which are associated with diabetes. DHEA does this through a complex interaction with the hormones adiponectin and insulin. As insulin levels rise with insulin resistance, adiponectin falls. This hormone imbalance will result in Diabetes for many people.

Additionally, Type II Diabetes has been shown to be the result of chronic inflammation. What does that mean, you ask? Chronic, dysregulated inflammation causes insulin resistance. What is the source of this inflammation, you ask? Fat cells! The obesity epidemic is the root cause of our current healthcare crisis.

Let’s go back to the patient’s hormone therapy. Her test results showed her deficient in progesterone. Becauseprogesterone is a natural anti-inflammatory, it is currently being used in traumatic brain injuries (TBI) to reduce inflammation and improve outcomes. In addition, women with low progesterone tend to have significantly more menstrual cramps, the result of inflammatory signals called prostaglandins. Progesterone therapy has been shown to reduce those prostaglandins and thus reduce menstrual cramps.

Are my hormones in appropriate balance?

Hormones don’t exist in a vacuum, as many seem to think. Hormones exist in a delicate balance. The most well publicized imbalance is that of the estrogens and progesterone.  Imbalance of estrogen and progesterone have been linked to many health problems: fatigue, weight gain, headaches, and increased risk of breast cancer to name a few.

I often tell patients that with every cause there is an effect. You can’t give one hormone without affecting many others. The addition of progesterone to the body when it has been chronically low will not only restore progesterone to an appropriate physiologic level, but will also allow estrogen signals to work better. The balance of hormones allows each hormone to work as it was intended. Mind you, we are NOT talking about using synthetic hormones which are simply not what the body is looking for and contain harmful additives. We only treat with bioidentical hormones (bioidentical hormone replacement therapy, also known as BHRT). 

Is my body metabolizing my hormones in the right way? 

The final key point is looking at how the body processes hormones (metabolism). Hormone metabolism is just as important as the individual hormone levels and the hormone balance. 

Let’s use estrogen metabolism, for example. Estrogens (there are actually three different types of estrogen) can be metabolized three ways: 2-hydroxy estrone, 4-hyroxy estrone, and 16-alpha-hydroxy estrone. Some of the risks associated with estrogen come from the body metabolizing estrogen utilizing the 4-hydoxy estrone pathway. This pathway results in many dangerous metabolites (break down products). Think of it as turning down the wrong road as you’re driving somewhere, and you end up in a briar patch!

Think about it. Many women with breast cancer and men with prostate cancer don’t take bioidentical estrogen nor do they take synthetic estrogen. Their problem, as it relates to hormones, comes from endogenous hormone production (the body’s own hormone overproduction or underproduction), hormone metabolization, and the often undiscussed environmental xenoestrogens (from environmental toxin exposure). In lay terms, the body is metabolizing estrogen using the 4-hydoxy estrone pathway resulting in higher risk of cancer.

It has only been in the last 50 to 60 years that major hormonal imbalances in industrialized countries seem to have come to our attention. Before that, people and their hormones seemed to do just fine for thousands of years. We can attribute much of that to diminishing nutritional value in our foods and continually increasing exposure to toxins. Nutrition and toxins both have profound effects on the body, hormones included.

In conclusion, why should a patient take hormones (BHRT)?

The answer is a summary of the three points we’ve looked at here. By determining current hormone levels, restoring balance, and evaluating the body’s metabolic processes, the body can once again function as God intended it. Should a patient be on hormones? Well, only if you need them. But the truth is few of us have perfectly balanced hormones due to nutrition, toxin exposure, and prescription medication side effects.

At Seasons Wellness Clinic, we use state-of-the-art testing that reveals your body’s biochemistry. With our years of advanced training, we can carefully customize a treatment plan to restore your body, offsetting the damage of poor nutrition, toxins, and prescription drugs. Our goal is to eliminate any need for prescription medication! We want you to be HEALTHY!

WELLNESS IS POSSIBLE! You don’t have to settle for a body that is not working as it should. You can make a conscientious choice towards good health and a longer, happier life.

Hormone Imbalance a Contributing Factor in Breast Cancer

Dr. Nathan Goodyear

Hormone Replacement Therapy (HRT) increases breast cancer. Have you read headlines like that? Or perhaps you were told that HRT caused someone’s breast cancer.

Do hormones really cause or lead to breast cancer? Think about this: every women continues to produce hormones, even after menopause. So, it cannot be that hormones in and of themselves cause cancer. Scientific evidence indicates thatsynthetic hormones and hormone imbalance do contribute to breast cancer.

The ABC’s of Estrogen.

Estrogen’s effects in the body are regulated through two different kinds of receptors: alpha and beta receptors. Estrogen-alpha receptors stimulate breast cell growth. Estrogen-beta receptors inhibit breast cell growth.

  • Estradiol, the most potent estrogen, equally stimulates alpha and beta receptors = growth stable
  • Estrone, the second most potent estrogen, stimulates alpha receptors 5:1 over beta receptors = pro growth
  • Estriol, the weakest variety of estrogen, actually stimulates beta receptors 3:1 = growth inhibitory

The key element here is balance of hormones. Higher levels of estrone present in your body (produced by fat cells) result in more breast stimulation. Higher levels of estriol present in your body results in less breast cell stimulation and, therefore, breast protection. Estriol = Good. Estrone = Bad. If you have heard of someone developing breast cancer after starting Premarin, there’s a logical explanation for that. Guess what Premarin is loaded with? Premarin contains (48%) estrone (estrone = bad = breast cell stimulation).

Here are some more ugly facts about Premarin, also know as conjugated equine estrogen. Premarin actually decreases estrogen beta receptors. So, if you take Premarin, then you are taking high doses of estrone (estrone = bad) and decreasing your estrogen receptors that inhibit breast cell growth. In a nutshell: you are taking more of the bad estrogen and decreasing your amount of the good estrogen. This equates to a prime set up for breast cancer.  Don’t take my word for it. See the wonderful article by Kent Holtorf.

Progesterone: The Growth-Inhibitor Hormone

The confusion out there about estrogen and breast cancer is bad enough, but the confusion is even greater on the subject of progesterone.

Pregesterone is the key hormone in the second half of a woman’s cycle. Estrogen is the dominant hormone in the first half of your cycle (estrogen = growth = growth of the uterine lining to support implantation of an egg). The counteractive hormone to this growth phase is progesterone (progesterone = no growth = sloughing off of the uterine lining). It’s the amazing and fascinating way that woman was created.

progesterone-vs-provera

Synthetic progestins, often prescribed, are NOT the same as the progesterone your body produces. Just look at the structure and you see that they are not. The one thing they do have in common is they both protect the lining of the uterus against excessive estrogen growth. But, that is where the similarities end.

While there are many differences between the two, our focus here will be on the difference in breast cancer potential. Simply stated, synthetic progestins are pro-breast cancer and bioidentical progesterone is breast protective. The Women’s Health Initiative (link) revealed a 26% increase in breast cancer as a result of taking synthetic progestin. The Nurse’s Health Study (link) found that synthetic progestins tripled breast cancer risk over that of estrogen only. The use of Provera, a synthetic progestin and component of Prempro, has been shown to increase the risk of breast cancer by 800%!

The statistics for bioidentical progesterone are the opposite. Bioidentical progesterone has many positive breast benefits:

  • Progesterone decreases estrogen production
  • Progesterone moves estradiol to weaker estrone
  • Progesterone moves estrone to inactive (sulfated) form
  • Progesterone moves estrone to weakest/safest estriol
  • Progesterone down-regulates estrogen receptors all together
  • Progesterone activates the cancer protection gene, p53

The idea that progesterone is a safer alternative to synthetic progestins is not new at all.  As early as the early 80’s, there has been a call for safer progesterone over synthetic progestin counterparts. In 1981, nearly 30 years ago, L.D. Cowan showed that just having low progesterone levels increases the risk of premenopausal breast cancer risk 5.4 times.

Unfortunately, progesterone-deficient states, (or estrogen dominance) are very common in women today as a result of many factors: being overweight, PCOS, environmental xenoestrogens, excessive estrogen therapy, and perimenopause. Another study, showed progesterone to have a 400% decreased breast growth rate.

The Scientific Evidence Is Clear.

The evidence in the scientific literature is clear with regards to estrogens, progesterone, and hormone balance.

  • Bioidentical and synthetic hormones should NOT be used interchangeably. They are not equal. They have very different physiologic effects on the breast:  synthetic progestins (Provera notably) increase breast cancer (800%) and bioidentical progesterone protects against breast cancer (400% decrease breast growth rate).
  • Estrogen therapy is not for everybody and is definitely not a panacea drug; in fact estrogen dominance is a major contributor to breast cancer risk. But if estrogen therapy is needed, then estriol (Estriol = good) is the best.
  • Hormone balance is the key. Without estrogen and progesterone balance, a women’s cycles are irregular, and infertility can be a big problem.
  • You know, once we understand hormones and the balancing cycle between estrogen and progesterone, it makes perfect sense that imbalance would cause breast problems. And the scientific evidence indicates just that. In honor of Breast Cancer Awareness Month, it’s time make sure your hormones are balanced and protect yourself from breast cancer.

    Who’s Afraid Of The Big Bad Bioidentical Hormone?

    Dr. Nathan Goodyear

    What is Progesterone? Do women need progesterone after a hysterectomy? Does it cause cancer as some have been told? Does it disrupt the thyroid as some also have been told? What is truth? What is fiction? What does the evidence show?

    Let’s work through some of these questions systematically.

    What is Progesterone?
    Progesterone is the hormone a woman’s body produces after ovulation each month. It balances the effect of estrogen in the uterus and throughout the body. When everything is working well in your body, estrogen and progesterone balance each other to create a normal menstrual cycle. However, when progesterone levels fall and estrogen dominates, a woman can experience heavy bleeding, irregular cycles, PMS, weight gain…

    Some folks would have you believe that synthetic progestins (especially Provera) are identical to progesterone. This just isn’t true. They are not similar in http://ww5.komen.org/, structure, or function. Progestins and progesterone do both protect of the lining of the uterus from excess estrogen. But that is where the similarities stop!

    Race for the Cure… and a Better Understanding of Women’s Health
    Breast cancer research has received a lot of attention lately through wonderful campaigns like Race for the Cure, Breast Cancer Awareness Month, and similar efforts. All of this research has given us some wonderful insights into women’s health in general. Specifically, the research has revealed clear distinctions between bio-identical progesterone and synthetic progestins.

    Seasons 'Race for the Cure' T-Shirt

    Numerous large studies have shown that synthetic progestins, such as Provera, increase a woman’s risk of breast cancer. In contrast, bio-identical progesterone can reduce a woman’s risk of breast cancer. This has been clearly tested and consistently confirmed. In fact, just having low progesterone levels makes a woman 5.4 times more likely to get premenopausal breast cancer. Even worse, such women are significantly less likely to survive a fight with breast cancer.

    As a doctor, I am horrified by these statistics, and I want to help—through my own practice and through an attempt with many other doctors to educate women.

    As a scientist, I am amazed that something as simple as progesterone deficiency results in a higher breast cancer risk.

    Seasons Team, Racing for the Cure!

    Still Not Convinced?
    Here’s a quick summary of the down and dirty science. Estrogen is a powerful stimulant to breast cell growth. (Remember, cancer is unregulated cell growth). When researchers added synthetic progestin, the growth of breast cells increased significantly. In contrast, when researchers added progesterone, breast cell growth decreased by 400%.

    And here’s what that means. A woman’s body needs progesterone even after a hysterectomy. Progesterone doesn’t cause cancer—in fact, the opposite is true! Finally, a woman’s thyroid is not disrupted by progesterone—again, the opposite is true!

    Progesterone is safe. Women’s bodies produce it for a reason. They need it.

    Bioidentical Hormones: What Does The Scientific And Medical Evidence Say?

    Dr. Nathan Goodyear

    A young lady came into my office the other day to discuss hormones. She was a breast cancer survivor. Her concern, and rightly so, was her risk of getting breast cancer again. Since she lived in the south (our main office is in Ruston, Louisiana), she had experienced the women’s ritely passage of menopause: “the hysterectomy ceremony.”

    Her question to me was: can she take hormones? Years ago, her cancer doctor had placed her on premarin, telling her that it was safe. She also was told that because she had a hysterectomy, progesterone was not necessary. Her gynecologist, in contrast, told her she couldn’t take premarin. Different doctors, different opinions.

    I’m not trying to offer a third opinion here. I just want to stay focused on the evidence. That is what evidence-based medicine is all about. Unfortunately, market forces are clouding evidence-based medicine today.

    In earlier posts, I’ve talked about progesterone, synthetic progestins and their polar opposite effects on a woman’s breasts. Progesterone lowers risks. Progestin increases risks. I want to get a little more specific today with some information from an outstanding review of the evidence. In Dr. Kent Holtorf January 2009 article, the Bioidentical Hormone Debate, he exhaustively reviewed 196 research articles. (If you aren’t up to reading the full article, you can read an abstract of the review.)

    Here is my summary of the risks associated with synthetic progestins:

    • increased breast cell growth
    • increased conversion of weaker estrogens into more potent estrogens
    • promoted the formation of toxic estrogen metabolites (16-hydroxyestrone)
    • stimulated the conversion of inactive estrogen to active estrogen (estrone sulfate to estrone)
    • had anti-apoptotic effects. (Apoptosis is programmed cell death: which is a way to control cancer growth. Anti-apoptosis means your body lacks this method of controlling cancer growth.).

    Contrast this with the benefits of the natural bioidentical hormone progesterone.

    • reduced breast cell growth by 400%
    • downregulated estrogen receptors in the breast
    • induced cancer cell apoptosis (programmed cell death that helps control cancer growth)
    • reduced breast cell division and growth
    • and in some studies, progesterone actually arrested human breast cancer cells.

    After looking at nearly 200 independent studies, Dr. Kent Holtorf concluded that “Both physiological and clinical data have indicated that progesterone is associated with a diminished risk for breast cancer, compared with the increased risk associated with synthetic progestins.” Studies have shown that synthetic progestins increase the risk of breast cancer:

    1. by approximately by 25% for each 5 years of use
    2. by triple the risk (67%) of breast cancer when added to estrogen therapy
    3. double the risk to 4% per year when compared to estrogen therapy alone.

    This is in stark contrast to bio-identical progesterone, which reduces the risk of breast cancer by 10%.

    “As far as the east is from the west”—that is how different the effects of progesterone and synthetic progestins are on the breast. Holtorf concludes his article in Postgraduate Medicine with statements like this: “With respect to the risk for breast cancer, heart disease, heart attack, and stroke, substantial scientific and medical evidence demonstrates that bioidentical hormones are safer.”

    In my next post, I’ll look at synthetic premarin versus bioidentical hormone estrogen.

    All Estrogens Are Not Created Equal

    Dr. Nathan Goodyear

    There is a lot of confusion in the medical and non-medical communities regarding estrogens. Many today think there is only one estrogen. Many today think bioidentical estrogens and synthetic estrogens are identical in structure and function. Many today think estrogen production stops after menopause or after a total hysterectomy. However, this couldn’t be further from the truth.

    The body never stops producing estrogens. The body, in fact, produces 3 types of estrogens: estradiol, estrone, and estriol. These are the natural estrogens native to the body and the foundation of bioidentical hormone replacement of estrogen.

    A woman’s body produces estrogens in various places. Most people knows that ovaries produce estrogens. But did you know that the adrenal glands and fat cells produce estrogens, too? Think about that for a minute. This explains why women of all ages continue produce estrogen. Our adrenal glands don’t disappear at menopause. And fat cells certainly don’t. So how do we know if a woman needs estrogen?

    Let’s look more closely at the 3 main estrogens produced in the body.

    • estradiol
    • estrone
    • estriol

    Estriol is a good place to start. Estriol is the weakest of all Estrogens. A woman’s placenta produces very large amounts of estriol during pregnancy. However, estriol is not confined to pregnancy. The liver produces small amounts, too. Estriol primarily affects a woman’s hair, nails, skin, and her vaginal lining. Studies also suggest estriol has potential in breast cancer prevention because estriol binds to specific receptors (beta-receptors) in the breast that inhibit breast cell growth. All other estrogens would be expected to increase breast cell growth (which can lead to cancer) through activity with alpha-receptors.

    Estrone is the second most potent estrogen. Estrone is predominately produced in fat cells after menopause. Overweight women have high circulating estrone levels. Unfortunately, 63% of American women are overweight or obese, so many women have high estrone levels. Estrone levels rise even more after menopause, and estrone has been implicated in breast tumors in animal studies. (Scientists say this because estrone has a 5:1 affinity for alpha breast receptors, but that’s pretty technical.) Just remember that alpha-receptors increase breast cell growth. You could say estrone encourages breast cell growth, and that can lead to uncontrolled breast cell growth. We call that breast cancer.

    Estradiol is the most potent estrogen. Estradiol is produced predominately from the ovaries. This means a woman will have less estriadiol after menopause because her ovaries are producing less. Estradiol is the main stimulus for growth of the lining of the uterus in the first 2 weeks of the monthly cycle, and it helps in triggering ovulation. Like estrone, estradiol has been implicated in breast tumors. It has a 3:1 affinity for alpha-receptors in the breasts, which promote breast cell growth and can lead to cancer.

    That’s a lot of information for one blog post, I know. But remember the overall point. Bioidentical hormone therapy is much more than the use of bioidentical estrogen. It is about which estrogens your body needs to maximize efficacy, reduce side effects, and prevent disease.
