Poop pills from skinny donors: a new weapon against obesity?

NCT ID NCT06268990

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed pilot study tested whether transferring gut bacteria from lean donors or from people who had gastric bypass surgery could improve metabolism in 29 obese adults with prediabetes or diabetes. Participants received fecal transplants, and researchers measured changes in insulin sensitivity and blood sugar. The goal was to see if changing gut bacteria could help manage obesity and related conditions.
