Gastric bypass surgery:
It is a surgery through which the size of the stomach is reduced by connecting the upper part of the stomach and diverting its path immediately to the small intestine so that the food goes to the upper section only without the lower section, and therefore when the patient eats a little food he feels full immediately as if his stomach was full of food. The process takes between 2 to 4 hours.
Candidates for gastric bypass surgery:
Gastric bypass cannot be performed on anyone, but these conditions must be availabled, the most important of which are:

Stages of gastric bypass surgery
The gastric bypass process goes through three important stages:
Anesthesia stage:
In this stage, the patient is given general anesthesia, to avoid feeling any pain during the operation.
Gastric banding stage:
At this stage, the doctor ties the upper part of the stomach, which is a relatively small section that can accommodate 28 grams of food, so that the food is directed directly to it, without going through its large lower section, and therefore the patient will be required to eat small amounts of food.
Diversion stage:
In this stage, the doctor transfers the upper part of the stomach (gastric pouch) directly into the small intestine and connects it with it through a small hole through which food moves from the gastric pouch to the small intestine.
