Bloating: What Your Gut Is Really Trying to Tell You

Bloating is not random. It is the result of a highly active biological system. This episode explains how the large intestine functions as an anaerobic bioreactor, why fermentation produces short-chain fatty acids such as butyrate, acetate and propionate, and how gases like hydrogen, CO₂ and methane reveal the true metabolic state of your microbiome.

You’ll learn how the intestinal H₂-economy works, how methanogens, sulfate reducers and acetogens compete for hydrogen and why the same meal can trigger completely different reactions in different people. The episode also breaks down the key mechanisms behind FODMAPs, polyols, visceral hypersensitivity, SIBO and the migrating motor complex. It highlights why modern eating patterns overwhelm the microbiome and how a sudden increase in fiber can trigger a “fiber shock”.

A clear, scientifically grounded exploration of the biological logic behind bloating, gas formation and food intolerance. Concise, relatable and free of myths.
