NCT ID NCT07375797
First seen Jun 27, 2026 · Last updated Jul 15, 2026 · Updated 2 times
Summary
This study tests whether transferring gut bacteria from a healthy donor (fecal transplant) can improve blood sugar control in 16 adults with type 2 diabetes. Participants receive either the transplant or a placebo, and researchers measure insulin sensitivity and blood sugar levels over 7 weeks. The goal is to see if changing gut bacteria can help manage diabetes, but this is an early-stage, small study.
