Gastric bypass surgery, also known as Roux-en-Y gastric bypass, is an effective obesity surgery method that supports weight loss by reducing the size of the stomach and rearranging a part of the small intestine. At NY HEALTH in Istanbul, gastric bypass surgeries are performed to provide safe, controlled and long-term weight loss to patients using advanced surgical techniques. Our goal is to support patients not only in losing weight, but also in improving their overall health and quality of life.


Clinical assessment, travel planning, and follow-up are presented in one clear, patient-friendly flow.
Gastric bypass surgery is the process of creating a small gastric pouch in the upper part of the stomach and connecting this pouch to a further part of the small intestine.
Thanks to this method, both the amount of food consumed decreases and the absorption of nutrients decreases. As a result, calorie intake is restricted, which contributes to significant and sustainable weight loss.
Treatment planning, transfers, accommodation, and clinical checks are coordinated in one patient journey.
