How Long Poop Stays in Your Body Could Have a Surprisingly Big Impact on Your Disease Risk

A 2023 review in Gut says gut transit time is a major but often overlooked driver of microbiome composition and activity.

Transit time can vary with diet, age, sex, exercise, stress, medication, and genetics.

Too slow or too fast transit may change bile acids, short-chain fatty acids, and other gut signals.

These shifts could be linked to higher risk of IBS, IBD, colon cancer, and some neurological diseases.
