A gastric bypass is often recommended for people with type 2 diabetes or significant reflux. It is a longer operation than a sleeve and needs careful follow-up. Here is how it works when you travel from the UK to Istanbul.
Sleeve or bypass?
A sleeve reduces the size of the stomach; a bypass also re-routes part of the small intestine, reducing absorption. Bypass is often preferred with type 2 diabetes or reflux. The general surgeon chooses after your tests; you can ask for both options to be explained in writing.
How the price is set
The bypass price depends on the technique (Roux-en-Y or mini bypass), your health and the length of stay, so it is quoted after a free assessment rather than as a fixed number. The package includes the operation at a licensed hospital, hospital stay, hotel, transfers, tests, coordinator and complication insurance; flights are not included.
Your stay
The keyhole operation takes about 2–3 hours, with 2–3 nights in hospital. Most patients fly home on day 6–8.
After you are home
Lifelong vitamins and regular blood tests are part of life after a bypass. We provide an English discharge summary for your GP and remain available by WhatsApp.
Questions to ask any clinic
Who is the surgeon, how many bypasses do they perform, which hospital, what is in writing about complications and follow-up?

Frequently asked questions
Is a mini bypass the same?
No. A mini (one-anastomosis) bypass has one connection instead of two; the surgeon explains which suits you.
Will my diabetes improve?
Many patients see improvement, but results vary and no outcome can be guaranteed.
Can a sleeve be converted to a bypass later?
Yes, this is a common revision operation, decided after assessment.
