Gastric Bypass (Roux-en-Y gastric bypass) is a surgical procedure that aims to achieve significant weight loss by reducing the size of the stomach and the absorption of food. The procedure involves creating a new, smaller stomach pouch and bypassing part of the small intestine to limit food intake and calorie absorption.
Gastric bypass can lead to significant and rapid weight loss. The surgery can also help treat obesity-related diseases such as type 2 diabetes, heart disease, high blood pressure or high cholesterol.
Gastric Bypass is one of the most common types of bariatric surgery, combining restrictive and malabsorptive procedures.
How does gastric bypass work?
In Roux-en-Y gastric bypass a new, smaller stomach pouch is created and part of the small intestine is bypassed. This limits how much you eat and how many calories you absorb.
