The PCOS Thyroid Connection - Erica Armstrong
Introduction
I wrote this book for women who have struggled with symptoms for months or years without understanding why they were experiencing them and without explanations from health care professionals. Many of these women began to think that the way they feel is just how life is going to be. Maybe I just need to learn to live with it,
they would tell me when we first met at my functional medicine practice.
I’m a medical doctor who spent 8 years as a primary care physician in family medicine. Over the years, women would tell me they are just so exhausted, that their memory isn’t as sharp, that their hair is falling out, and that suddenly their skin looked like they were a teenager again. I listened and I saw the pattern. I knew they were telling the truth. All of these women couldn’t have possibly been experiencing such a similar constellation of symptoms without reason.
As a conventional doctor, I didn’t have as many tools in my tool box as I do now after studying and practicing functional medicine and nutrition. Back then, I would do all the labs I could think of to run, knowing at the time I was ordering them that they would probably come back normal.
Then, my option would be the same option that is often correct on medical board exams: reassurance.
Unfortunately, these women didn’t just want reassurance. They wanted answers. They wanted to feel energy to thrive in their professional and personal lives.
As I learned more in functional medicine, the more everything made sense. Hormone imbalances are very real. Thyroid function can still be a significant factor in how people feel even though labs are in normal ranges (We’ll explain more here in this book!). Symptoms like acne and bloating and diarrhea and fatigue are in fact all connected by root causes. Often those root causes are found in the gut and the transformation that happens when the gut heals is remarkable.
I left conventional medicine and went out on my own because I could not ignore the power of functional medicine any longer. I needed to practice this way because it worked and people felt better and it just makes sense to me. I started a small practice and partnered with a dietitian, knowing the power of food and nutrition on health.
The two of us had a passion for PCOS and thyroid at the outset and we’ve been tracking our members progress, successes in restored hormone balance, fertility, symptom reduction in cravings, fatigue, and even mood over the last three years.
We work in a doctor and dietitian team and the protocols we’ve developed and refined after treating hundreds of women with PCOS and Thyroid conditions are doable, realistic, and sustainable. We are so excited to share them with you so that you can also achieve these results using the steps in this book.

PCOS and Hashimoto’s Connection
Throughout my practice as a functional medicine physician specializing in women’s health, I helped many women with similar symptoms. Many of these women were suffering from a wide range of symptoms, like digestive issues, brain fog, acne, fatigue, carb cravings, irregular periods, fertility concerns, trouble with sleep, or hair changes. These women had some or all of these symptoms and had different reasons or goals for seeking treatment. Yet, two hormonal conditions causing these symptoms seemed to pop up together quite frequently: polycystic ovary syndrome (PCOS) and Hashimoto’s thyroid disease.
While seemingly affecting very different parts of the body, these two conditions continue to show up in pairs in many of the women I treat. What is the connection between these two unique disorders?
If you’ve picked up this book, then chances are you are one of the number of women who may have polycystic ovary syndrome, thyroid disease, or both. The first half of this book aims to review the unique connection and similarities between PCOS and Hashimoto’s thyroid disease and break down the root causes so that you can begin to find your own root cause.
The second half of this book will provide you with our proven 3-month system to begin to reverse these conditions. Unlike many other functional medicine books, we did not want to advertise a 30 day cure,
30 day Challenge,
or 30 day Plan.
What you will learn in this book is sustainable for a lifetime, because it is realistic and it works beyond 30 days and the 3 months we have outlined. Resetting hormone balance by treating the root cause issues is a journey and this method will help you take control in a way that you will achieve and continue to achieve. The lifestyle habits developed over the 3 months become easier to follow, and as we have seen in our practice, can completely reverse symptoms.
The 3-month plan described in this book is very similar to the program we use for our individual members of our practice all over the country. It is tried, tested, and backed by evidence-based research. The approach we use is called functional medicine, which simply means that we investigate and optimize the body’s function by respecting that the body works together as an intricate system and not isolated organs or body parts.
What is Functional Medicine?
You are unique. You have your own genetic makeup, health history, and lifestyle. Your treatment plan should be unique to you too. Functional medicine is an approach to treating health conditions and preventing disease by finding the root cause of your health issues. However, instead of stamping you with a diagnosis and only treating your symptoms, functional medicine doctors find out why you have the diagnosis. They will do an in-depth assessment to look at all of your body systems (not just the one causing symptoms), and evaluate how well your body is communicating. Then, functional medicine doctors will recommend interventions to help restore balance by addressing factors such as nutrition, movement, stress, sleep, and gut health.
Functional nutrition is a powerful cornerstone to functional medicine. It uses food as a natural medicine to help restore balance, replete nutrient deficiencies, heal the gut, and more.
Personalization is the main difference between functional and conventional nutrition.
Functional nutrition focuses on the patient instead of the disease. It is a personalized method of optimizing your health based on your individual genetics, lab values, lifestyle, and more. There are no generic meal plans or handouts, because each individual person is different! Functional nutrition honors the fact that food is not only fuel for your body, but also an extremely useful tool to help us address the underlying cause of your condition. A functional medicine dietitian may recommend certain anti-inflammatory foods, gut-healing compounds like glutamine or probiotics, or targeted supplements to replete any nutrient deficiencies based on lab testing.
When you identify and treat the root causes of your hormonal imbalances, you will find that your body works like a beautiful symphony. This book will show you how to start loving your body and working with it, not against it.
What is PCOS?
Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders affecting women of reproductive age and is the leading cause of female infertility in the United States. Depending on the criteria for diagnosis, PCOS may affect up to 20 percent of all women, although an estimated 70 percent of women with PCOS may be undiagnosed (1). As suggested in the name, polycystic ovary syndrome is a reproductive disorder that involves enlarged ovaries that may house multiple cysts. For women in their reproductive years (typically ages 15-49), the ovaries produce and release an egg into the reproductive tract at the midpoint of the menstrual cycle each month. This is known as ovulation. The ovaries are also responsible for producing reproductive hormones like estrogen, progesterone, and to a much smaller degree, testosterone.
Female anatomy: The egg starts in the ovary, travels down the fallopian tube, and if fertilized, implants in the uterus.
While the name may lead you to believe that PCOS only affects the ovaries, it actually involves your whole endocrine (hormone) system as well. In fact, the main hormones involved in PCOS are insulin, which is made in the pancreas, and testosterone. Imbalances in these two hormones can lead to typical PCOS symptoms for which women often seek medical care: irregular periods, acne, facial hair growth or thinning hair on the scalp, and infertility. Some women may also have cysts on their ovaries; however, this is not necessarily required for a PCOS diagnosis.
There are a few significant risk factors that increase your chances of developing PCOS like having a family history of the condition, or a diagnosis of type 1, type 2, or gestational diabetes. Due to hormonal imbalances, a history of weight gain often occurs before developing other signs of PCOS. While weight may increase your risk of PCOS, research shows that the effect is very modest. For example, one study found the risk of PCOS between normal-weight and overweight women—based on body mass index (BMI)—only varied by 0.1 percent (1). Ultimately, there is much more to this complex condition than the number on a scale.
Signs and Symptoms of PCOS
PCOS is classified as a syndrome and not a disease, which is partly why it may seem so confusing. Nonetheless, most women with PCOS will ultimately seek medical care related to four common complaints: irregular periods, acne, facial hair growth or thinning hair on the scalp, or infertility. Yet, PCOS encompasses a broad spectrum of clinical signs and symptoms that many women may not even realize.
Table 1 shows common signs, symptoms, and health conditions that women with PCOS may experience. The estimated percent of women with PCOS affected by these conditions is reported as well (1).
Table 1
*For clarification, in the women reporting infrequent periods, an estimated 85-90 percent of them will have PCOS while 30-40 percent of women with absent periods will have PCOS.
This list is not exhaustive of all possible symptoms seen in PCOS and many of these conditions are intricately connected. For instance, insulin resistance can often lead to weight gain or difficulty losing weight. Consequently, this weight gain can worsen other clinical signs like high blood pressure or high cholesterol.
Diagnosing PCOS
The most common criteria used to diagnose PCOS is the Rotterdam criteria. This is a list of three criteria that have shown to accurately capture the women who have PCOS.
For a definitive PCOS diagnosis, women must meet at least two of the following three criteria:
Clinical and/or biochemical hyperandrogenism (hair loss on head or hair growth on face, hormonal acne)
Infrequent ovulation or absence of ovulation (which leads to irregular or absent periods)
Polycystic ovaries
In order to confirm a PCOS diagnosis, your health provider must exclude any other potential causes of absent ovulation or hyperandrogenism, like thyroid disease, Cushing’s syndrome, hypothalamic amenorrhea, and androgen-producing tumors. Let’s discuss each of the PCOS diagnostic criteria in more detail.
Clinical and/or Biochemical Hyperandrogenism
Androgens are sex hormones present in both men and women but with higher concentrations found in men. The main androgens include testosterone, androstenedione, and dehydroepiandrosterone sulfate (DHEA-S). In women, androgens are produced by the ovaries, adrenal glands, and fat cells.
When a woman’s body produces too many androgens, known as hyperandrogenism, the resulting clinical symptoms are usually dermatological in nature: acne, excessive facial or body hair (hirsutism), or thinning hair on the scalp (alopecia). Hyperandrogenism is present in about 60 to 80 percent of PCOS cases (2).
While clinical symptoms alone often hint at hyperandrogenism, confirming excess androgens with a blood test allows for further investigation. To test for hyperandrogenism, your health provider may order a blood test including total serum testosterone and DHEA-S. In our practice, we often look at additional functional testing, like the DUTCH test, which can also show metabolism of these hormones and additional hormones.
There are no universal reference ranges for these blood tests, so each laboratory may have different cutoffs for what is considered normal. We’ll discuss androgen testing more in chapter four.
Infrequent Ovulation or Absence of Ovulation
The menstrual cycle is a natural hormonal change that occurs monthly in women during their reproductive years. It begins with the onset of bleeding typically referred to as your period or menstruation. We call the first day of menstrual bleeding day one of your monthly cycle. Around the midpoint of your menstrual cycle, an ovary releases an egg into the reproductive tract—this is known as ovulation. If the egg is not fertilized by a sperm cell, the lining of your uterus will eventually shed which triggers bleeding and the beginning of your next menstrual cycle. From beginning to end, a healthy menstrual cycle typically lasts between 24 and 35 days.
