HCA Talks Health
The Root Mechanism of Chronic Illness
Gluten, Inflammation & Your Brain with Dr. Tom O'Bryan
Published: 31st July 2026
What if the real driver behind so many of your clients' chronic health struggles could be traced back to one root mechanism?
In this eye-opening conversation, internationally recognised functional medicine expert Dr Tom O'Bryan busts a common health myth head-on: "There is no root cause to disease. There are many causes." But there's only one root mechanism driving nearly every chronic condition, and that mechanism is inflammation. For Health Coaches, this shift changes how you can support your clients.
Known as the "Sherlock Holmes of Chronic Illness", Dr O'Bryan reveals how systemic chronic inflammation quietly fuels autoimmune disease and cognitive decline. For any health and Health and Wellness Coach ready to move beyond symptom care and truly investigate root causes, this episode is a genuine game changer.
What you’ll learn in this episode:
Why systemic inflammation sits at the heart of chronic illness & how to help clients spot it
How gluten triggers leaky gut & molecular mimicry in every human
Why standard gluten-free diets can backfire & the Mediterranean Gluten-Free approach
Simple, empowering micro-changes your clients can make to lower inflammation
How to grow from symptom care into a confident Health Coach & true root-cause investigator
