What Is the Difference Between Gastric Sleeve and Gastric Bypass?

Both Gastric Sleeve and Gastric Bypass are effective bariatric procedures that help patients achieve significant and long-term weight loss. While both surgeries reduce food intake, they work in different ways.

Gastric Sleeve removes approximately 75–80% of the stomach, creating a smaller stomach pouch that limits food intake and reduces hunger hormones.

Gastric Bypass creates a small stomach pouch and reroutes part of the small intestine. This limits calorie absorption while also reducing food intake.

Your surgeon will recommend the most suitable option based on your BMI, medical history, eating habits, and overall health goals.

Which Procedure Is Better?

There is no single "best" procedure for everyone.

Generally,

• Gastric Sleeve is often preferred for patients with obesity who do not have severe reflux disease.

• Gastric Bypass may be recommended for patients with severe acid reflux, uncontrolled Type 2 Diabetes, or those requiring greater metabolic improvement.

The final decision should always be made after a detailed medical evaluation.

Recovery

Most international patients stay in Turkey for approximately 5–7 days after surgery.

Walking begins on the day of surgery, while normal daily activities usually resume within 2–4 weeks, depending on individual recovery.

Following your nutrition plan and attending follow-up appointments are essential for achieving the best long-term results.
