Gastric Bypass

Gastric bypass, also known as bariatric surgery, is a surgical method used to treat obesity. The main purpose of this surgery is to help patients with obesity to lose weight. Gastric bypass surgery provides weight loss through two main mechanisms of action:

Stomach Reduction: During the surgery, a large part of the stomach is bypassed, i.e. deactivated. This results in a smaller stomach capacity and the patient eating less food.

Bypassing the Small Intestine: During surgery, part of the small intestine is also bypassed. This reduces the absorption of nutrients and promotes weight loss.

Since gastric bypass is a serious surgical intervention, it is usually recommended for patients who have not been successful in losing weight with methods such as diet and exercise. This surgery not only helps patients lose weight, but also improves other obesity-related health problems.

Gastric bypass surgery

Roux-N-Y Gastric Bypass surgery has decreased with the development of techniques that cause less absorption defects while it was the most common procedure in the 2000’s. It keeps the most commonly used method in Europe.  

Roux-en-Y Gastric Bypass is an operation which both minimizes stomach capacity and restricts absorption. It reduces the amount of foods you eat, and at the same time it ensures some of the nutrients’ disposing without absorbing.

Gastric bypass reduces stomach size by over 90%. The normal stomach may enlarge, sometimes up to 1000 ml. The gastric bypass pouch is 15-30 ml in size. The gastric bypass pouch, that is, the area created for the stomach, is made in the upper part of the stomach, which can stretch very little, and thus, there is no significant increase in the volume of the pouch in the long term.

How is Rny-Gastric Bypass Surgery Performed?

With the planned obesity surgery, your stomach is divided into two main sections, one of which is quite small, using special surgical materials (Laparoscopic). The system is arranged by connecting the small stomach section to be formed to an area approximately 50-70 cm long from the initial part of the small intestine, and reuniting the two intestines that will allow your bile and pancreatic secretions to reach the 100-150 cm area that continues after this level. As a surgical procedure, it is aimed to reduce the volume of food taken due to the newly created small gastric pouch (30-50 cc). Secondly, as a result of the late encounter of the small amount of food eaten with pancreatic and bile fluids, it provides weight control by preventing the intake of all the calories it contains.
