How Long Poop Stays in Your Body May Impact Your Health, Study Finds - ScienceAlert

A recent study finds that how long stool stays in the gut — the transit time — is linked to differences in the gut microbiome, markers of inflammation, and measures of metabolic and intestinal health. Faster or slower transit may change microbial composition and the exposure of gut tissues to microbial products, with potential implications for disease risk and overall wellbeing. These findings connect to practical bowel‑health advice about diet and toilet habits, to research on colorectal disease mechanisms, and to work on the gut's influence on brain function.
