What is gastric bypass surgery?
Gastric bypass surgery is performed by a surgeon in a hospital or surgery center under general anesthesia. The completion rate of this operation is from 48 hours to 5 days. This surgery is performed on adults and sometimes teenagers. The surgeon creates a small bag, which is about the size of an egg, from the patient's stomach tissue and connects it to the lower part of the small intestine. By doing this, it bypasses the area of the duodenum and the beginning of the small intestine. In this surgery, when the stomach becomes smaller, the person eats less food. Also, by bypassing the upper part of the intestine, fewer calories and nutrients are absorbed by the body. It means that the amount of food eaten decreases and then the amount of absorption of the swallowed food decreases.Who can perform gastric bypass surgery?

Possible risks of gastric bypass operation
A number of risks such as blood clots and bleeding may occur with any surgery. Some risks associated with gastric bypass surgery include:
- Dumping syndrome: the too fast movement of food from the stomach to the small intestine. which can cause nausea, severe diarrhea, lightheadedness and cold sweat. Malnutrition: This surgery reduces the body's ability to absorb nutrients. As a result, a person may suffer from a lack of minerals and vitamins.
- Leakage: Gastrointestinal leakage of digestive juices and partially digested food can occur where the small intestine is connected to the stomach or where it connects to its lower end. Small bowel obstruction: Small bowel obstruction usually occurs due to an internal hernia. This condition occurs when the intestine protrudes through a defect in the abdominal cavity.
- Marginal ulcer formation: It occurs near the junction of the stomach pouch and the small intestine and is similar to a stomach ulcer.
- Gastric Fistula: Gastric fistula refers to the abnormal passage between the new stomach pouch and the rest of the old stomach. Anastomotic stenosis: the small vein is called anastomosis. If the connection between the stomach bag and the small intestine is broken, it will lead to the inability to swallow liquids.
