Some people need a second operation years after a gastric sleeve, most often because of reflux or weight regain. Revision surgery is more complex than a first operation, so the assessment before it matters even more. This guide explains the options.

The two common reasons are reflux that does not settle with medication and significant weight regain. Less often, a narrowing or a problem from the first operation needs correcting. The cause decides the operation.
The options
Converting a sleeve to a gastric bypass is the most common revision and often helps reflux. A mini (one-anastomosis) bypass is another option for weight regain. A re-sleeve is considered only in selected cases. The general surgeon explains which suits you and why.
Tests before surgery
Bring your previous operation report if you have it. A gastroscopy and imaging of the stomach are usually done in Istanbul before the decision, along with blood tests.
Stay and price
Plan 2–3 nights in hospital and about 6–8 days in Istanbul. Because each revision is different, the price is given in a written quote after the free assessment. It includes the operation, hospital stay, hotel, transfers, coordinator and complication insurance; flights are not included.
After you are home
After a bypass, vitamins and blood tests are needed for life. You receive an English discharge summary for your GP and we stay in touch by WhatsApp.
