What if autoimmune disease isn't something you're destined to live with forever, but a signal that your body needs help addressing deeper root causes?
In this episode of Modern Thyroid and Wellness, McCall McPherson welcomes longtime mentor, friend, and functional medicine pioneer Amy Myers. A two-time New York Times bestselling author and internationally recognized functional medicine physician, Dr. Myers shares her personal journey from being diagnosed with Graves' disease during medical school to becoming one of the leading voices in autoimmune and thyroid health.
Together, they explore why autoimmune diseases continue to rise, why women are disproportionately affected, and why many patients spend years searching for answers before receiving a diagnosis. Dr. Myers explains the role of gut health, environmental toxins, infections, stress, trauma, and nutrition in autoimmune disease while sharing practical strategies for supporting immune health and addressing root causes. She also introduces the newly revised edition of The Autoimmune Solution, featuring updated research and expanded guidance for today's changing health landscape.
Whether you're living with Hashimoto's, Graves' disease, or another autoimmune condition, this conversation offers hope, practical tools, and a reminder that healing begins by understanding the "why" behind your symptoms.

🌿 From Graves' Disease to Functional Medicine
Dr. Myers' journey into functional medicine began with her own health crisis.
While attending medical school, she developed severe anxiety, tremors, insomnia, weight loss, and other symptoms that were initially dismissed as stress.
After insisting on additional testing, she was diagnosed with Graves' disease.
Although conventional treatment successfully managed her thyroid, she realized no one had addressed why her immune system attacked her thyroid in the first place.
That experience ultimately led her to discover functional medicine and dedicate her career to helping patients identify and address the root causes of autoimmune disease.
🧬 Why Autoimmune Disease Is Becoming More Common
According to Dr. Myers, autoimmune disease isn't simply being diagnosed more often.
She believes multiple environmental factors are contributing to a true increase in autoimmune conditions.
Among the biggest contributors discussed are:
- Environmental toxins
- Chronic infections
- Processed foods
- Plastic exposure
- Chronic stress
- Gut dysfunction
- Modern lifestyle changes
She explains that while genetics influence susceptibility, environmental exposures often determine whether those genes become active.
👩 Why Women Are More Commonly Affected
Women account for the majority of autoimmune diagnoses.
Dr. Myers explains that significant hormonal transitions often coincide with the development or worsening of autoimmune disease.
Common life stages include:
- Pregnancy
- Postpartum
- Perimenopause
- Menopause
These hormonal shifts can influence immune regulation and may contribute to the onset of autoimmune symptoms in genetically susceptible individuals.
⏳ Autoimmunity Often Begins Years Before Diagnosis
One of the most important messages in this episode is that autoimmune disease develops long before many people receive a diagnosis.
Dr. Myers explains that antibodies may be present for years before symptoms become severe enough to trigger additional testing.
During this time, people often experience symptoms such as:
- Fatigue
- Brain fog
- Hair loss
- Joint pain
- Digestive problems
- Weight changes
Unfortunately, these symptoms are frequently attributed to stress, aging, or hormonal changes rather than early autoimmune disease.
🩺 The Four Pillars of Autoimmune Healing
Dr. Myers describes a comprehensive approach that focuses on identifying and addressing the underlying drivers of immune dysfunction.
Her four pillars include:
Heal the Gut
Supporting digestion and restoring the intestinal barrier through nutrition, digestive support, probiotics, and treatment of underlying gut infections.
Improve Nutrition
Removing inflammatory foods while emphasizing nutrient-dense whole foods that support immune balance.
Reduce Toxic Burden
Minimizing exposure to environmental toxins while supporting the body's natural detoxification pathways through hydration, sweating, regular bowel movements, and targeted nutritional support.
Address Hidden Triggers
Identifying chronic infections, reducing stress, and addressing unresolved trauma that may contribute to persistent immune activation.
Together, these pillars form the foundation of her functional medicine approach to autoimmune health.
🦠 Why Gut Health Comes First
Dr. Myers refers to the gut as "the gateway to health."
She explains that many people with autoimmune disease also experience:
- Leaky gut
- Candida overgrowth
- SIBO
- Parasites
- Poor digestion
Before attempting to rebuild the microbiome, she emphasizes identifying and treating these underlying issues while also removing inflammatory foods that may continue to drive immune dysfunction.
🧪 Monitoring Thyroid Antibodies
For thyroid patients, Dr. Myers emphasizes that antibody testing provides valuable information beyond standard thyroid hormone levels.
She recommends:
- Establishing baseline antibody levels
- Monitoring antibodies more frequently during active treatment
- Periodic long-term monitoring once antibodies remain stable
She also notes that patients who have undergone thyroid ablation or thyroid surgery may still produce thyroid antibodies and should continue monitoring when appropriate.
🌟 Final Takeaway
Autoimmune disease is not simply a matter of bad luck or genetics.
As Dr. Myers explains, our environment, nutrition, gut health, stress, infections, and daily habits all influence how our immune system functions.
While every autoimmune journey is unique, understanding and addressing these root causes can create meaningful opportunities for healing and improved quality of life.
Most importantly, a diagnosis doesn't have to mean giving up hope.
With the right approach, many people can reduce inflammation, improve symptoms, and support long-term immune health.
