Gastric pouch resizing (GPR) for Roux-en-Y gastric bypass (RYGB) failure yields a 53% success rate at 10 years, defined as >50% excess weight loss (%EWL) and/or resolution of comorbidities, despite a 47% failure rate characterized by significant weight regain.
If you have regained weight after a Roux-en-Y gastric bypass, it may be due to your stomach pouch stretching. Gastric pouch resizing is a surgical option that can help restore restriction. However, be aware that nearly half of patients experience significant weight regain within 10 years. This procedure is most effective for those with a specifically dilated pouch and may help resolve other health issues like GERD, but it is not a guaranteed long-term fix for everyone.
This study shows that GPR after RYGB results in a failure rate, defined as %EWL < 50% and/or persistence, recurrence, or de novo development of at least one obesity-related comorbidity of 47% at the 10-year follow-up... Moreover, we found that the resolution of comorbidities is maintained over time despite a significant weight regain.
Why this rating
Single-center, retrospective longitudinal cohort with small sample size (n=20), though long-term follow-up is a strength.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
