Bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy) is technically feasible and safe for patients with pre-existing ileostomy or colostomy, without causing increased ostomy output or dehydration.
If you have an existing ostomy (ileostomy or colostomy) and are considering bariatric surgery, current preliminary evidence suggests it is feasible and safe, with no increased risk of dehydration or output changes compared to patients without an ostomy. Consult with a bariatric surgeon to evaluate your specific case, as individual factors like the cause of your ostomy and overall health status will determine your candidacy.
Bariatric surgery is technically feasible in selected patients with ileostomy/colostomy with a reasonable short-term safety profile.

- 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
