Gastric bypass is an older type of surgery than other obesity surgical methods. First, a small stomach with a volume of 30 ml is created. For this, stomach tissue is used near the esophagus stomach junction. The small intestines are connected at a certain distance to this newly created small stomach. There are two types of bypasses.
Obesity Treatment Methods
In one type, the small intestines are connected to the stomach by forming a ring without ever leaving. This is called mini gastric bypass. In the other type, the small intestine is separated and one end is attached to the stomach and the other end to the small intestine. This is called RouxEn-Y gastric bypass.
The mechanism here is that the tube is not only restrictive as in the stomach which the patient can consume more limited food quantity but also the foods encounter in the small intestine sections much more distant from the place where they should be with bile and pancreatic enzymes spilled into the duodenum. Therefore, food breakdown and absorption become difficult and an impurity-destroying mechanism is attached.
Briefly, the patient consumes less nutrient, and benefits less from the consumed nutrient. Here, the change in the hormones of the gastrointestinal system becomes more pronounced than the tube stomach. Therefore, the sense of hunger decreases, the feeling of satiety increases, and the blood glucose is stable, the patient may give 60-80% of the weight. It is a method of limiting food intake.
Surgery is usually performed between the ages of 18-65. Some conditions are necessary for the patient to undergo surgical procedure.
