An obese patient, not diabetic, treated with metformin for some weeks, was referred to us with severe inferior digestive hemorrhage, diagnosed with Meckel's diverticulum. Metformin is described as a glucose‐lowering agent for treatment of type 2 diabetes mellitus and as antiobesity drug, though results achieved with this last indication are not conclusive. But metformin has fibrinolytic features by means of diminished plasminogen activator inhibitor 1 activity. Although no coagulation study was done and the Meckel's diverticulum is normally associated with bleeding, the particular intensity of the following hemorrhage may have been favored by metformin.
