Gastric Bypass Surgery in Turkey
Gastric bypass combines a smaller stomach with a rerouted digestive path — an effective option for significant weight loss and for improving type 2 diabetes and reflux.

Gastric Bypass options we arrange
Roux-en-Y gastric bypass
A small stomach pouch is created and connected directly to the small intestine, reducing both food intake and absorption.
Mini gastric bypass (OAGB)
A single-connection bypass with a longer stomach pouch, often with a shorter operating time.
Revision surgery
Conversion of a previous sleeve or band to a bypass when weight regain or reflux occurs.
Is it right for you?
Gastric Bypass may be suitable if you have:
- Adults generally with a BMI of 35 or more, or 30+ with metabolic conditions
- Patients with type 2 diabetes or significant acid reflux
- Weight regain or reflux after a previous sleeve or band
- Willingness to take lifelong supplements and attend follow-up
The final decision is always made by your doctor after a detailed review of your medical history and, where needed, tests in Istanbul.

Gastric Bypass: frequently asked questions
How is a bypass different from a sleeve?
A sleeve only reduces stomach size. A bypass also reroutes the intestine, which can have a stronger effect on diabetes and reflux, but requires lifelong vitamin supplements.
Will I need vitamins forever?
Yes. Because absorption is reduced, daily vitamin and mineral supplements and regular blood tests are needed for life.
What is dumping syndrome?
Eating sugary or fatty food after a bypass can cause nausea, sweating and dizziness. Following the nutrition plan helps you avoid it.
Can a sleeve be converted to a bypass?
Yes, in many cases. Revision surgery is assessed individually by the surgeon.
