Ep 207 NIH CFS Study: Advancements in Chronic Fatigue Syndrome Research Part 2
Jun 18, 2025
Dive into groundbreaking research on Chronic Fatigue Syndrome (CFS) that reveals new diagnostic standards and biological abnormalities. Discover how the Hingston Criteria may change clinical trials and the crucial role of the autonomic nervous system. Hear about 'effort preference' and its implications for muscle strength and cognitive effort in patients. Explore insights on chronic stress and its complex relationship with health, along with previews of future findings from functional MRIs in CFS research.

Personal CFS Journey and Hope
A woman with chronic fatigue syndrome shared her exhausting, invisible illness journey starting from a high fever to months of debilitating symptoms.
Her story highlights the struggle for diagnosis and the importance of patient communities for support and hope.
insights INSIGHT
Autonomic Imbalance in CFS
Chronic fatigue syndrome patients show lower heart rate variability, indicating reduced autonomic nervous system flexibility.
This reflects sympathetic nervous system dominance, causing chronic stress symptoms like inflammation and fatigue.
insights INSIGHT
Shared Physiology of Chronic Stress
Functional somatic syndromes and stress-related syndromes share physiological traits like higher resting heart rates and reduced stress response.
This suggests they may have overlapping biological mechanisms linked to chronic sympathetic dominance and stress wear.

Dr. Michael Lenz's "Conquering Your Fibromyalgia" offers a comprehensive approach to understanding and managing fibromyalgia. The book delves into the complexities of the condition, exploring its connection to other chronic pain syndromes and neurodivergence. It provides evidence-based strategies for pain management, emphasizing lifestyle modifications and patient-centered care. The book also addresses common misconceptions and advocates for greater empathy in healthcare. It aims to empower readers with knowledge and tools to improve their quality of life.
In this episode, we delve into the ongoing research and new findings related to Chronic Fatigue Syndrome (CFS). The discussion covers the development of standardized diagnostic criteria known as the Hingston Criteria, as well as the discovery of biological abnormalities in CFS patients. Key areas of focus include the autonomic nervous system, heart rate variability, and muscle strength. The episode also touches on the concept of 'effort preference' and the complex interplay between sympathetic and parasympathetic nervous system activity in chronic conditions like CFS and fibromyalgia. Additionally, the episode previews upcoming discussions on findings from functional MRIs of the brain in CFS patients.

When I started this podcast—and the book that came before it—I had my patients in mind. Office visits are short, but understanding complex, often misunderstood conditions like fibromyalgia takes time. That’s why I created this space: to offer education, validation, and hope. If you’ve been told fibromyalgia “isn’t real” or that it’s “all in your head,” know this—I see you. I believe you. You’re not alone. This podcast aims to affirm your experience and explain the science behind it. Whether you live with fibromyalgia, care for someone who does, or are a healthcare professional looking to better support patients, you’ll find trusted, evidence-based insights here, drawn from my 28+ years as an MD.
Please remember to talk with your doctor about your symptoms and care. This content doesn’t replace personal medical advice.*
