What is Gastric Bypass?

Gastric bypass is a type of bariatric surgery aimed at helping individuals achieve significant weight loss. This procedure reduces the size of the stomach and alters the digestive system, limiting food intake and nutrient absorption. Gastric bypass is typically recommended for individuals who have not had success with other weight loss methods such as diet, exercise, and medication.

How is it Performed?

Gastric bypass surgery involves two main steps:

Stomach Reduction:

The surgeon creates a small pouch at the top of the stomach. This pouch significantly reduces the overall stomach capacity, making the patient feel full after consuming a small amount of food.

Bypassing the Intestines:

The newly created stomach pouch is then connected directly to the middle part of the small intestine, bypassing a portion of the stomach and the upper part of the small intestine (duodenum). This alteration reduces the absorption of calories and nutrients.

Benefits
