Gastric sleeve

Now that’s a good looking gastric sleeve! Sleeve gastrectomy is a surgical weight-loss procedure in which the stomach is reduced to about 30% of its original size, by laparoscopic surgical removal of a large portion of the stomach, following the major curve. The open edges are then attached together (often with surgical staples) to form a sleeve or tube with a banana shape. The procedure permanently reduces the size of the stomach. The remaining stomach is restricted in size and volume, hence, limits the amount of food that can be eaten at one time. The stomach fills up with less food, which results in weight loss. The second mechanisms by which a sleeve gastrectomy works is hormonal. By removing the gastric fundus, there is a deceased production of the “hunger hormone” called Ghrelin. This hormone is produced in the stomach and its main function is to regulate hunger and induce it. Once the hormone is produced in the stomach, it travels through the bloodstream to reach the brain and once there there is the feeling of hunger and anxiety to eat. Decreased levels of ghrelin promotes weight loss by inducing satiety.
