Abstract
At 12 months, RYGB patients lost an average of 40.7 kg, significantly more than those undergoing SG or LAGB.
- Roux-en-Y gastric bypass (RYGB) led to a weight loss of 40.7±14.5 kg compared to 24.4±22.1 kg for sleeve gastrectomy (SG) and 15.3±15.7 kg for laparoscopic adjustable gastric band (LAGB).
- Body mass index (BMI) reduction was 13.4±4.1 kg/m² for RYGB, while it was 7.9±7.3 kg/m² for SG and 5.0±5.0 kg/m² for LAGB.
- Percentage weight loss (%WL) was 31.5±8.5% for RYGB, compared to 20.2±21.5% for SG and 12.0±11.7% for LAGB.
- Percentage excess weight loss (%EWL) for RYGB was 41.4±11.6%, while SG and LAGB showed 26.7±27.6% and 16.1±15.9%, respectively.
- RYGB also resulted in a significant reduction in the number of medications and improvements in total cholesterol and low-density lipoprotein (LDL) levels.
