Hospital metformin debate: keep or stop? small study offers few answers.
NCT ID NCT06296836
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether people with type 2 diabetes should continue taking their usual metformin medication while hospitalized. The goal was to see if it helped control blood sugar, caused stomach issues, or affected how long patients stayed. Only 22 people took part before the study was stopped early, so the results are not strong enough to guide treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- metformin
- What this could lead to
- If successful, this could help doctors decide whether to continue metformin during hospital stays, potentially improving blood sugar control and reducing complications.
- What could go wrong
- The study was terminated early with only 22 participants, so results are not reliable. It is a small, single-center trial with limited scope.
