Weight Loss Surgery
Mini Gastric Bypass
Simplified single-anastomosis bypass — comparable weight loss to Roux-en-Y with shorter surgery and potential reversibility.
Is it safe?

Will the price change?
Your price is locked before you book. Surgery, hospital, hotel, transfers, aftercare — one number, no extras.

24/7 WhatsApp with your coordinator. Scheduled video check-ups with your surgeon. 12 months, not 12 days.

Frequently Asked Questions
Mini gastric bypass uses a single intestinal connection instead of two, resulting in a shorter and less complex operation. Weight loss outcomes are comparable, and the simplified anatomy may carry a lower complication rate.
The procedure is potentially reversible due to its simplified anatomy, though reversal is rarely needed. The single anastomosis makes restoration of normal anatomy less complex than reversing a Roux-en-Y bypass.
Bile reflux is a theoretical concern with single-anastomosis procedures. However, the long stomach pouch and appropriate limb length used in modern MGB technique minimise this risk. Your surgeon will evaluate your reflux history during the pre-operative assessment.
Mini gastric bypass typically produces greater weight loss than gastric sleeve (60-75% vs 50-60% excess weight loss) due to its additional malabsorptive component. It is also more effective at resolving metabolic conditions such as type 2 diabetes.
Yes. Lifelong supplementation with vitamins B12, D, iron, calcium, and a daily multivitamin is required. MedProper provides a personalised supplementation protocol and monitors your nutritional status during follow-up.
