    In gastric bypass operation, a pouch is created by cutting the upper part of the stomach with surgical intervention. This formed pouch is approximately the size of a walnut and can only hold up to 30 ml of food. After this stage, the surgeon makes an incision into the small intestine and connects it directly to the newly made pouch. When you start eating again after the operation, the food goes into this small sac of the stomach and directly into the small intestine. The foods taken into the body bypass most of the stomach and the beginning of the small intestine, and at the same time, weight loss is achieved by 2 different mechanisms by reducing the volume of the stomach.
