What is Gastric Bypass?
Gastric bypass is a metabolic and bariatric surgery that alters the digestive system to reduce food intake and limit calorie absorption.
During the procedure:
• The stomach is divided into a small upper pouch and a larger lower section
• The small intestine is rearranged to connect to the new pouch
• A portion of the digestive tract is bypassed
This reduces:
• The amount of food that can be eaten
• The absorption of calories and nutrients
The most commonly performed technique is the Roux-en-Y gastric bypass.
Who Is a Candidate for Gastric Bypass?
Gastric bypass in Istanbul may be considered for individuals who:
• Have a BMI over 40
• Have a BMI over 35 with obesity-related conditions (such as type 2 diabetes, hypertension, or sleep apnea)
• Have struggled with long-term weight management
• Are medically evaluated as suitable for bariatric surgery
A full metabolic and internal medicine assessment is required before surgery.

How Is Gastric Bypass Performed?
Gastric bypass is performed under general anesthesia.
Procedure overview:
• Several small incisions are made in the abdomen
• A laparoscope (small camera) is inserted
• The stomach is divided to create a small pouch
• The small intestine is rerouted and connected to this pouch
• The digestive pathway is reconstructed
Surgery typically lasts 2–3 hours.
The lower portion of the stomach remains in the body but no longer directly receives food.
