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

The amount of time stool stays inside your body strongly influences your gut bacteria, short-chain fatty acid production, inflammation levels, and metabolic health Researchers found that slower gut transit shifts bacteria away from carbohydrate fermentation and toward protein fermentation, increasing irritating compounds like ammonia and hydrogen sulfide inside the colon A simple blue stool test revealed that people with slower transit times had poorer blood sugar control after meals, higher visceral fat levels, and less favorable metabolic markers High-fat diets slow intestinal movement and create a gut environment linked to constipation, poorer energy production, and bacterial imbalance Your stool texture acts like a daily gut health report card, and improving movement, hydration, and easier-to-digest foods helps restore healthier bowel transit and a more balanced microbiome
