Size of the stomach is reduced in the way that only 10-15% portion of it remains. A new connection is formed between the downsized stomach and a specific spot of the small intestine.

Thus, with a decrease in the volume of the stomach, weight loss occurs due to a decrease in portions of food. In addition to this, weight loss is targeted by reducing the absorption of other nutrients in the small intestine, especially high-calorie foods, by shortening the distance that nutrients proceed in the small intestine. As with sleeve gastrectomy surgery, the remaining part of the stomach is not removed in gastric bypass surgery, and the connection between this part and the esophagus is severed, resulting in no food intake. But the remaining part of the stomach continues to produce the enzymes essential for digestion. After the operation performed laparoscopically, the time for patients to return to their work and social lives is quite short.

What Are The Benefits of Gastric Bypass Surgery?

Due to the fact that the stomach shrinks with gastric bypass, a decrease in food portions occurs and rapid weight loss occurs in a short time. 

Co-morbid diseases such as diabetes, hypertension that occur due to obesity are also treated and other diseases that may occur are prevented. The treatment of diseases such as gastric hernia and acid reflux also takes place during the operation.

What Are The Types of Gastric Bypass Surgery?

Gastric bypass surgery is divided into two types; Roux-en-Y gastric bypass and mini gastric bypass.

Purpose of these two surgeries can be listed as follows:
