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.
