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

Key Points:

• A 2023 review analyzing data from multiple studies found significant differences in gut microbiomes between individuals with fast ("speeders") and slow ("slowpokes") gut transit times, which may impact overall health.
• Slow gut transit and constipation have been linked to metabolic, inflammatory, and neurological disorders, including Parkinson's disease, highlighting the importance of understanding microbiome profiles associated with transit times.
• The study showed that gut transit time influences microbiome composition and diversity, with fast transit favoring carbohydrate-utilizing species and slow transit favoring protein-utilizing species, both exhibiting lower diversity than average transit times.
• Measuring gut transit time, using tools like the Bristol Stool Scale or sensor-equipped capsules, could improve predictions of gut microbiota and help personalize dietary and treatment strategies, including probiotic effectiveness.
• Researchers emphasize that incorporating gut transit time into microbiome studies may enhance prevention, diagnosis, and treatment of various diseases by providing a clearer understanding of gut-diet-microbiome interactions.
