Summary

Obese patients exhibit considerable heterogeneity and complex comorbidities, making long-term effective management challenging with single therapies. While bariatric surgery remains the most effective weight-loss intervention, postoperative weight regain and metabolic deterioration require attention. GLP-1 RAs offer distinct advantages for weight and metabolic improvement, and their combined application with surgery may yield synergistic benefits. This study investigates the efficacy and safety of bariatric surgery combined with GLP-1 receptor agonist adjuvant therapy for severe obesity.

BS-GLP group

1. Basic Treatment Measures Within 0-30 days after sleeve gastrectomy, all patients received very low-calorie enteral nutrition powder (100 kcal/day). From 30 to 90 days post-surgery, a low-energy diet (400 kcal/day) was provided. Beyond 90 days post-surgery, a calorie-restricted diet was implemented (1,500 kcal/day for men and 1,200 kcal/day for women). 2. In addition to laparoscopic sleeve gastrectomy and postoperative basic nutritional counseling,the intervention group received subcutaneous semaglutide injections from 1 to 6 months postoperatively.The specific protocol was as follows:In the intervention group, semaglutide treatment was initiated at 1 month after LSG. The starting dose was 0.25 mg per week and was subsequently titrated up based on individual patient response to a maximum maintenance dose of 2.4 mg per week. The treatment continued until the completion of the 6-month postoperative period.
