EP 13 | IBS & Diet Management

IBS affects up to one in ten people — and dietary advice around it is famously confusing. Here is what the evidence actually says about FODMAPs, fiber, prebiotics, probiotics, and how to manage IBS step by step.

About this episode

Irritable bowel syndrome is one of the most common gut conditions in the world — and one of the most misunderstood. Sufferers are bombarded with conflicting dietary advice: cut this, add that, avoid entire food groups. It is exhausting, and much of it is not backed by evidence.

In this episode, Dr. Kash Gupta brings clarity. He explains what IBS actually is, the different IBS subtypes, the red-flag symptoms that should never be ignored, and the fascinating science of the gut-brain axis — including the surprising role of serotonin in gut function.

From there, it is a practical deep dive into diet: FODMAPs explained, the evidence behind the low FODMAP diet and its three phases, the difference between soluble and insoluble fiber, which prebiotics are low FODMAP friendly, and where probiotics and fermented foods genuinely fit in. It all builds to a clear, stepwise approach to managing IBS you can actually follow.
