The Gut–Immune Connection: Why Leaky Gut Drives Autoimmunity & Food Allergies
If you’ve ever wondered why your immune system feels “on edge” — reacting to foods, flaring during stress, or launching autoimmune attacks — this episode breaks it all down. Most people are told their immune system is “broken,” but the truth is simpler: your gut barrier controls your immune behavior.
In this episode of Healthcare Rewritten, Dr. Lena and Dr. Collin unpack how leaky gut, microbial imbalance, and chronic inflammation confuse the immune system — and how repairing the gut barrier can transform autoimmune symptoms, fatigue, food reactions, and chronic congestion.
• Real story: Dr. Collin’s personal autoimmune journey — from IBD flares and elimination diets to uncovering gut permeability, mold exposure, and inflammation at the root.• Patient transformations: How hundreds of patients with Hashimoto’s, IBD, lupus, Grave’s, psoriasis, eczema, and even “mystery ANA positives” have improved by addressing gut barrier damage.• Science simplified: Zonulin, tight junctions, immune confusion, and why 70%+ of the immune system lives in the gut mucosa.• Myth busting: Why probiotics, food allergy panels, and elimination diets aren’t enough to reverse autoimmunity.• Real solutions: Drainage, gut repair nutrients, microbiome diversity, stress modulation, and retesting timelines.• Empowerment: Your body isn’t attacking you — it’s defending you from what’s leaking through the gut wall.
✔️The exact tests we use: GI Map, Genova stool analysis, secretory IgA, zonulin, and calprotectin✔️The 5-step gut repair plan: Remove → Repair → Repopulate → Reduce stress → Re-evaluate✔️Why food allergies are symptoms, not diagnoses✔️How SCFAs (like butyrate) help calm autoimmune activity✔️The mindset shift that changes everything: “Your immune system isn’t broken — it’s confused.”
