Sponsor's own description

The aim of this observational study is to investigate the potential effects of metformin on postoperative nausea and vomiting (PONV) in patients undergoing surgery under general anesthesia. The primary research question is: Does preoperative metformin exposure influence the incidence or severity of PONV in patients undergoing general anesthesia? Patients who are already prescribed metformin as part of their routine medical management will be compared with those not taking metformin. Data on PONV occurrence, severity, and recovery outcomes will be collected through structured postoperative surveys administered after surgery.
