447: Bloating, SIBO + Leaky Gut: What’s Actually Causing Your Symptoms (And How to Fix It) with Dr. Karan Rajan

Dr. Karan Rajan is an NHS surgeon, gut health specialist, founder of LOAM, and host of the Dr. Karan Explores podcast. He joins the show to explain why so many people are constantly bloated, reacting to foods, and being told it’s “normal”—and what’s actually going on in your gut.

We break down the truth about “leaky gut,” the fiber deficiency epidemic, and how your microbiome is directly influencing your hormones, mood, and skin. Dr. Rajan also shares why many gut health trends are overcomplicated or misguided—from over-reliance on probiotics to restrictive protocols like low FODMAP—and what actually moves the needle when it comes to digestion.
