Your Poop Schedule Could Be Rewriting Your Gut's Microbial Map

A small 3-week study of 20 individuals found that how often people poop is linked to distinct gut microbiome profiles and metabolite production: those who pooped less often had greater microbial diversity and higher levels of bacteria such as Ruminococcus, while daily poopers had more Bacteroides, potentially affecting nutrient processing and health. Diet and gut transit time appear to shape these differences, suggesting a feedback loop between bowel habits and the microbiome. The findings add to the growing evidence that defecation frequency influences health, though larger, multi-omics studies are needed to clarify implications.
