Some surgeries are performed using traditional method (a large incision is made in the abdomen), whereas, most are performed laparoscopically (instruments are inserted through multiple incisions in the abdomen) After making the incisions, the surgeon cuts the top of your stomach, closing it off from the rest of your stomach. The newly made pouch is walnut sized and can hold about an ounce of food.
The surgeon will then cut the small intestine and sew part of it directly onto the newly created pouch. Then, the food will go into the newly created small pouch of the stomach and then directly into the small intestine. The food consumed by you bypasses the first section of your small intestine and most of your stomach and enters directly into the centre of your small intestine.
