First seen Jul 10, 2026 · Last updated Jul 10, 2026
Summary
This study tests whether people with type 2 diabetes who take their usual metformin on the morning of surgery have better blood sugar control and fewer problems like infections. Participants are randomly assigned to receive either metformin or a placebo before their operation. The goal is to see if this simple change can improve recovery and shorten hospital stays.
