| Let’s break down the real success rates of bariatric surgery—what the research shows, what long-term outcomes look like, and how you can stack the odds in your favor.
Different procedures yield different outcomes, but here are the average success rates after 2 years:
Sleeve Gastrectomy (LSG): 60–70% excess weight loss
Gastric Bypass (RYGB): 65–80% excess weight loss
Biliopancreatic Diversion with Duodenal Switch (BPD/DS): Up to 85% excess weight loss
These results are not just short-term. Studies show that most patients maintain 50–60% of their weight loss at 10 years post-surgery, especially if they adhere to follow-up care and lifestyle guidelines.

Lack of follow-up care or support
Stomach pouch or sleeve stretching over time
The good news? Most regain can be reversed with nutritional guidance, exercise, support groups, or even revision procedures if necessary.
