Bariatric surgery is a widely used intervention for significant weight loss, yet some patients face challenges with insufficient weight loss or weight regain post-surgery. To address this issue, adjunctive treatments like glucagon-like peptide-1 receptor agonists (GLP1-RAs) are being explored for their potential to enhance weight loss outcomes. This meta-analysis was conducted to evaluate the effectiveness of GLP1-RAs in improving weight loss after bariatric surgery compared to a placebo. By systematically reviewing and analyzing data from three randomized controlled trials (RCTs) involving 130 patients, we found that GLP1-RA therapy, particularly liraglutide (1.8-3 mg), significantly reduced mean BMI and body weight percentage at six months. Future studies should explore newer GLP1-RAs with weekly dosing and include longer follow-up periods to assess the durability of these outcomes.
