Gut bacteria swap may tame diabetes and thyroid disease

NCT ID NCT07733232

First seen Jul 29, 2026 · Last updated Jul 30, 2026 · Updated 1 time

Summary

This trial tests whether a one-time dose of fecal microbiota transplantation (FMT) — taking capsules containing processed donor stool — can improve blood sugar control and reduce thyroid antibodies in adults who have both type 2 diabetes and Hashimoto's thyroiditis. All 38 participants will receive the same FMT treatment and be followed for 24 weeks. The study asks whether restoring gut bacteria can help manage these two conditions at once.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
fecal microbiota transplantation (FMT) oral capsules
What this could lead to
If it works, this could point toward a new way to manage both blood sugar and autoimmune thyroid disease by restoring gut bacteria.
What could go wrong
This is a small, single-arm trial with no placebo group, so results may be due to chance. FMT can also carry risks like infection or digestive upset.
