The Root Causes Behind Hormone Imbalance, Gut Issues & HPA Axis Dysfunction | Betsy Stevenson
23.07.2026 | 45 min.What happens when every medical test comes back "normal," yet your body is telling you something is seriously wrong?
In this powerful episode of the Health Detective Podcast, Functional Diagnostic Nutrition Practitioner (FDN Practitioner) Betsy Stevenson shares her remarkable journey through years of unexplained neurological symptoms that mimicked mini-strokes, debilitating fatigue, digestive dysfunction, insomnia, hormone imbalance, and overwhelming burnout. Despite extensive medical testing, including MRIs, heart evaluations, CT scans, blood work, and specialist visits, she was repeatedly told everything looked normal.
Everything changed when Functional Lab Testing revealed profound HPA Axis dysfunction, extremely low cortisol, disrupted hormone health, impaired detox pathways, and deeper physiological imbalances that conventional testing had overlooked. Betsy explains how discovering Functional Diagnostic Nutrition, a true Health Detective approach, helped uncover the hidden stressors driving her chronic health challenges.
Together, Michele and Betsy explore why Root Cause Healing requires more than symptom management. They discuss the importance of Functional Medicine, Functional Diagnostics, personalized healing protocols, metabolic typing, nervous system regulation, lifestyle changes, restorative sleep, stress reduction, and bio-individual nutrition. Betsy also shares how improving Gut Health through comprehensive testing uncovered IBS, colitis, bacterial imbalances, Candida, and digestive dysfunction, allowing her to rebuild health from the inside out.
This conversation highlights why Holistic Health means treating the entire body as an interconnected system rather than focusing on isolated symptoms. If you've been struggling with Chronic Fatigue, Brain Fog, Hormone Issues, Digestive Problems, Food Sensitivities, Bloating, Blood Sugar instability, Metabolic Dysfunction, Burnout, or have been told your labs are "normal" despite feeling unwell, this episode offers hope, education, and practical insight into a different path forward.
Whether you're searching for Natural Healing, considering working with an FDN Practitioner, exploring Functional Nutrition, or looking for answers beyond conventional medicine, Betsy's story demonstrates how identifying hidden dysfunction can create lasting Health Transformation.

16.07.2026 | 1 godz. 30 min.Why do so many women continue battling fatigue, brain fog, weight gain, hormone imbalance, bloating, and food sensitivities, even when their lab results come back “normal”?
In this episode of the Health Detective Podcast, Michele Scarlet sits down with Dr. Stephanie Dunlop, a board-certified emergency medicine physician and founder of RootRX, to explore why conventional medicine often overlooks early dysfunction and how a root cause approach can uncover the hidden patterns behind persistent symptoms.
After experiencing her own unexplained postpartum health crisis and repeatedly being told that everything was "normal," Dr. Dunlop began searching beyond conventional care for real answers. She shares how comprehensive blood work, Functional Lab Testing, and a systems-based approach helped identify overlooked dysfunction involving Hormone Imbalance, Gut Health, Leaky Gut, low stomach acid, adrenal dysfunction, HPA Axis imbalance, chronic inflammation, cortisol, DHEA, Brain Fog, Burnout, Chronic Fatigue, and stress-driven metabolic changes.
Michele and Stephanie discuss why true healing isn't about chasing symptoms or relying on a single solution. Instead, they explain why restoring the body's foundations—including Nervous System regulation, digestive capacity, gut lining integrity, nutrient absorption, quality sleep, and stress resilience creates the conditions for lasting Root Cause Healing and sustainable Health Transformation.
The conversation also explores why "normal" lab ranges don't always reflect optimal health, how Functional Medicine interprets blood work differently, the importance of looking beyond TSH with markers like Free T3, the connection between chronic stress and digestive dysfunction, practical at-home assessments for stomach acid and gut health, and why identifying hidden stressors is essential before symptoms progress into more complex Chronic Health Challenges.
Whether you're a woman searching for answers after being told your labs are "normal," a Functional Health Practitioner, FDN Practitioner, Health Coach, or someone passionate about Functional Medicine, Functional Diagnostic Nutrition, Functional Nutrition, Root Cause Medicine, Holistic Health, Natural Healing, Functional Wellness, and evidence-informed Health Coaching, this episode offers practical insights into understanding the whole body, recognizing dysfunction early, and building a personalized path toward long-term health.

10.07.2026 | 1 godz. 30 min.In this special episode of the Health Detective Podcast, FDN Founder Reed Davis shares the remarkable story behind the creation of Functional Diagnostic Nutrition (FDN) and explains how a passion for helping people evolved into one of the world's leading Functional Health and Health Coaching education programs.
Reed reflects on his transition from environmental law into the wellness field after witnessing firsthand how conventional healthcare often failed to uncover the true causes of chronic health problems. Through years of working alongside chiropractors, nutrition professionals, and medical mentors, he developed a practical, data-driven system focused on identifying Hidden Stressors, restoring foundational health, and helping clients achieve lasting Health Transformation.
The conversation explores how Functional Lab Testing, saliva hormone testing, digestive assessments, detoxification markers, and other Functional Diagnostics shaped the FDN methodology. Reid explains why Root Cause Healing requires looking beyond symptoms to evaluate digestion, detoxification, hormone balance, immune function, energy production, and Nervous System health instead of relying solely on symptom management.
You'll also hear the origin of the FDN philosophy, including the development of the D.R.E.S.S. Protocol (Diet, Rest, Exercise, Stress Reduction, Supplementation), why practitioners focus on identifying Healing Opportunities rather than diagnosing disease, and how personalized lifestyle strategies support Holistic Health, Functional Wellness, and long-term resilience.
Reed also discusses mentorship, practitioner education, business building, and his mission to educate as many people as possible to help others get well and stay well naturally. Whether you're an aspiring FDN Practitioner, Functional Health Practitioner, Health Coach, or simply passionate about Functional Medicine, Root Cause Medicine, Functional Nutrition, and sustainable wellness, this episode provides valuable insight into the philosophy that continues to guide thousands of practitioners worldwide.How to Build a Bulletproof Health Coaching Business | Multiple Income Streams, FDN & Time Freedom

Together, they explore how a woman struggling with severe bloating, recurring H. pylori, parasites, reflux, constipation, dermatitis, fibroids, weight gain, exhaustion, and hormone challenges finally experienced lasting Health Transformation through a layered, whole-body approach. Rather than chasing symptoms or relying on aggressive protocols, Becca explains why supporting Functional Health begins with restoring digestive capacity, improving stomach acid, bile flow, nutrient absorption, and immune resilience before introducing targeted Healing Protocols.
She shares how Functional Lab Testing, blood work, and GI-MAP testing helped uncover hidden stressors driving chronic inflammation and why rebuilding the body's foundations produced long-term results.
The conversation also explores Gut Health, Hormone Health, Functional Medicine, Root Cause Healing, digestive enzymes, HCl, ox bile, immune support, fasting strategies, metabolic flexibility, and the importance of nervous system regulation. Michele and Becca discuss why many women dealing with Chronic Illness, Burnout, bloating, and hormone issues often need less stress, not more exercise, and why personalized care consistently outperforms one-size-fits-all protocols.
