Mini Gastric Bypass

What a mini gastric bypass involves

The mini gastric bypass — one-anastomosis gastric bypass, OAGB — creates a long, narrow stomach pouch and joins it directly to a loop of small intestine 150–200 cm down, bypassing the rest. There is one join instead of the two of a Roux-en-Y bypass, so the operation is shorter (about an hour), has fewer leak points and a lower rate of internal hernia, with weight loss and diabetes remission that are at least equivalent. It is now one of the most commonly performed bariatric operations in Europe and endorsed by IFSO.

The trade-off is a slightly higher risk of bile reflux and of nutritional deficiency than a sleeve, which is why lifelong vitamin supplementation and annual blood tests are part of the plan, not an option.

Who is eligible

BMI 35 and above, or 30 and above with type 2 diabetes or another obesity-related condition; age 18–65; previous serious attempts at weight loss. Patients with severe pre-existing reflux are usually steered toward a Roux-en-Y bypass instead. Pre-operative blood tests, ultrasound and an anaesthesia review are done on arrival.

Why Istanbul, and why through us

Our bariatric surgeons perform sleeve, bypass and mini bypass every week in a JCI-accredited hospital with a dedicated bariatric unit and intensive care. Private mini bypass costs £9,000–12,000 in the UK and €10,000–14,000 in Germany; here the full package with hotel and dietitian follow-up is a third of that, with a date within weeks.

You deal with one coordinator, one hospital and one medical team from the first message to the last follow-up. Every price is itemised in writing before you pay a deposit, and the written quote does not change unless you change the plan. Flights are never included.

Recovery and follow-up

Two to three nights in hospital with a leak test before discharge, then the recovery hotel; fly home day six or seven. Liquids for two weeks, puree for two, then soft food. Desk work at two weeks, sport at six. The dietitian follows you remotely at one, three, six and twelve months; you take a daily multivitamin, B12, iron and calcium for life.
