Mini Gastric Bypass

What Is Mini Gastric Bypass?

Also known as One-Anastomosis Gastric Bypass, it is a minimally invasive procedure that combines the benefits of gastric sleeve surgery and traditional gastric bypass.

Unlike the Roux-en-Y gastric bypass, which requires two intestinal connections, the mini gastric bypass involves only one connection between the stomach and the small intestine. This simplifies the procedure while maintaining excellent weight-loss and metabolic outcomes.

A larger gastric pouch is created compared to the classic bypass, similar in size to a gastric sleeve, allowing for more comfortable food intake, early satiety, and significant metabolic benefits.

Today, it is a widely used technique in bariatric and metabolic surgery due to its high effectiveness.

Who Can Undergo This Procedure?

Mini Gastric Bypass May Be an Option For:

People with a BMI between 30 and 40.
