What Is Gastric Bypass Surgery?
Gastric bypass surgery is a type of bariatric surgery designed to help individuals struggling with obesity. This procedure alters the stomach and small intestine, reducing food intake and calorie absorption, leading to significant weight loss from surgery. It is one of the most effective options for people who have not had success with diet and exercise alone.

Gastric bypass surgery is suitable for individuals who:
- Have a BMI of 40 or higher.

How Is Gastric Bypass Surgery Carried Out?
The most common type is Roux-en-Y gastric bypass. The procedure involves:
- Creating a small stomach pouch: A portion of the stomach is separated to form a small pouch.
- Bypassing part of the small intestine: The small intestine is rerouted to connect with the new pouch.
- Altering digestion: This reduces the absorption of calories and nutrients, aiding in weight loss surgeries.
