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.

Expected Results
Gastric bypass is considered one of the most effective bariatric procedures for long-term weight reduction.
Patients may experience:
• Significant excess weight loss

Long-term success requires:
• Dietary compliance
• Regular follow-up
• Lifestyle adaptation
• Psychological readiness
Risks and Considerations
As with all major surgeries, gastric bypass carries risks, including:
• Surgical complications
• Nutritional deficiencies
