The Efficacy and Safety of Liraglutide in Patients Remaining Obese 6 Months after Metabolic Surgery

Introduction The safety and efficacy of liraglutide as a weight loss intervention in individuals who remain obese within 1 year post-metabolic surgery remain unclear. This study aimed to evaluate the effects and safety of liraglutide (1.8 mg) in patients with persistent obesity at 6 months postoperatively. Methods This retrospective cohort study included 61 patients who remained obese (body mass index [BMI] ≥ 28.0 kg/m 2 ) at 6 months postoperatively. Among these patients, 27 were treated with 1.8 mg of liraglutide for 12 weeks, whereas 34 served as controls. The primary endpoint was the change in total weight loss (%TWL) after 24 weeks. Changes in weight, BMI, complications, and adverse events were also assessed. Results The liraglutide group showed a greater reduction in %TWL than the control group (11.6% ± 1.1% vs. 4.9% ± 1.0%), with an estimated treatment difference of 6.6% (95% confidence interval [CI], 3.7–9.6%, P
