Gastric bypass

What it is

A bariatric surgery that creates a small gastric pouch, about 10 % of the original size of the stomach, and connects it directly to part of the small intestine, forming a Y.

It is done laparoscopically, through small incisions and a camera, without opening the abdomen.

Benefits

• Supports significant, lasting weight loss.
• It can improve obesity-related conditions, such as type 2 diabetes.
• It reverses gastroesophageal reflux.

Important

How the process works

• Initial evaluation: in person or online.
• Preparation: prior tests and consultations with the multidisciplinary team (dietitian and psychologist).
• Surgery day: usually one night in hospital.
• Recovery: post-surgery check-up tests at 6 months and at one year. Check-ups with the multidisciplinary team as indicated.

After surgery

Your team teaches you how to organize your meals, what to eat and when.

Good hydration is essential, and we put special focus on muscle exercise from the 3rd or 4th week after surgery.

You lose between 60 % and 80 % of the excess weight. To reach the goal, patients must follow the instructions they are given and do muscle exercise.
