Leaky Gut, Toxins, and the Truth About Autoimmune Disease

Autoimmune disease isn't your body turning against you — it's your immune system doing exactly what it was designed to do. In this episode, Dr. Brad Montagne breaks down the real mechanism behind autoimmune conditions and why they've become so common.Dr. Brad explains how the immune system responds to only two things — inflammation and antigens — and why nearly 75% of immune activity is centered in the gut. He walks through how a compromised gut lining, often called "leaky gut," allows toxins, undigested particles, and bacterial byproducts to slip into the bloodstream, setting off the very immune response that shows up as autoimmune disease. The conversation also covers how everyday exposures — certain medications, pesticide residue on food (including "organic" produce), and airborne toxins — feed this cycle, and why restoring gut integrity, rather than simply suppressing the immune system, is the piece most conventional approaches miss.This episode is for anyone living with autoimmune symptoms, chronic inflammation, or unexplained health issues who wants to understand what's actually driving them rather than just managing the flare-ups.If you're ready to find out what's really going on beneath your symptoms, book a consult at healthfullyu.com and get your gut and toxic load properly evaluated.Topics:autoimmune disease causesleaky gut syndromegut health and autoimmune diseasefunctional medicine for autoimmune conditionsgut lining repairtoxic load and inflammationCandida overgrowthgut microbiome and immune systempesticide toxicity in foodroot cause of chronic illnesstight junctions and leaky gutenvironmental toxins and brain fogSummary: Dr. Brad Montagne explains how leaky gut and everyday toxin exposure trigger the immune response behind most autoimmune disease, and why restoring gut integrity — not suppressing the immune system — is the key to resolving it.Book a consult at healthfullyu.com to uncover the root cause of your autoimmune symptoms.
