The sleeve gastrectomy, also known as gastric sleeve surgery, is a restrictive procedure that limits the amount of food you eat by reducing the size of your stomach. This procedure is performed using the laproscopic or robotic-assisted technique.
During the gastric sleeve procedure, a thin vertical sleeve of stomach is created using a stapling device. This sleeve typically holds between 50-100 ml, about the size of a banana. The remainder of the stomach is removed.
By creating a smaller stomach pouch, a sleeve gastrectomy limits the amount of food that can be eaten at one time, so you feel full sooner and stay full longer. As you eat less food, your body will stop storing excess calories and start using its fat supply for energy.
