The procedure is a minimally invasive, and incisionless endoscopic procedure that usually takes less than 30 minutes. While you are sedated, your physician will insert a small camera attached to a thin and flexible tube through your mouth and into your stomach. A suturing device is connected to the tube, enabling stitches to be placed around the outlet and in some cases the stomach pouch itself. When these sutures are placed and pulled, the size of the outlet and gastric pouch will reduce in size, allowing you to restore the feeling of fullness, eat less, and ultimately lose weight again.
