Gastric bypass is a surgical procedure used to treat obesity. In this procedure, stomach reduction and bowel rerouting are performed. In this way, both the volume of the stomach is reduced and the absorption of nutrients is reduced.

In gastric bypass surgery, instead of a clamp that separates the stomach to shrink the stomach, the surgeon divides the stomach into smaller parts, making the upper part a smaller bag. In this way, the person can eat less food. Next, the surgeon cuts and redirects part of the intestines. Nutrients are absorbed by passing through these shortened intestines, which reduces the number of calories the body can take in.

Gastric bypass surgery is a very effective method in the treatment of obesity. With this method, about 60 to 80 percent of the person can lose weight. However, this method, like other surgical procedures, involves risks. These can include infection, bleeding, anesthesia problems, and intestinal problems.

Gastric bypass surgery can be considered in cases where other weight loss methods cannot achieve results and for the control of obesity-related diseases. However, before any surgical procedure, the risks and benefits should be carefully evaluated and consulted with a physician.
