Weight Loss and BMI Effects on Later Surgeries: Comparing GLP-1 Medicines and Weight-Loss Surgery

AI simplified

Abstract

A total of 9,470 individuals underwent general surgery procedures, with metabolic bariatric surgery () leading to a mean reduction of -9.89 compared to glucagon-like peptide-1 receptor agonists ().

  • Patients receiving MBS had a higher initial BMI, with 60.8% having a BMI of 40 or greater compared to 24.5% of those receiving GLP-1RA.
  • Higher BMI at the time of surgery is associated with increased postoperative complications and longer hospital stays.
  • MBS is linked to lower odds of complications compared to GLP-1RA.
  • The findings suggest that preoperative weight loss interventions may improve surgical outcomes for patients with obesity and type 2 diabetes mellitus.
