Faecal microbiota transplantation (FMT) using autologous stool preserves stimulated C-peptide levels (residual beta-cell function) in patients with new-onset type 1 diabetes over 12 months, whereas allogenic (healthy donor) FMT does not.

For individuals with very recent-onset Type 1 Diabetes, using their own gut bacteria (autologous FMT) may help preserve remaining insulin production, whereas using healthy donor bacteria does not offer this benefit. This is a specialized medical intervention, not a DIY protocol.

ModerateQualifiesMEDIUM confidence
Stimulated C peptide levels were significantly preserved in the autologous FMT group (n=10 subjects) compared with healthy donor FMT group (n=10 subjects) at 12 months.

Why this rating

Randomized controlled trial, but terminated early due to funding (n=20), limiting statistical power and generalizability.
