How does a sleeve surgery for weight loss work?

The stapling of stomach is done, determining the formation of a tube. This gastric tube, which becomes the new stomach, has an average capacity of 150 to 200 ml. A normal stomach (not operated) has an average capacity of 1500 to 2000 ml. Besides the reduction of the volume, which causes an early satiety, the sleeve surgery also causes weight loss because it results in the resection of the gastric fund, which is the main producer of ghrelin, a hormone responsible for increasing the appetite.  So, even if the levels of this hormone after the surgery are reduced, the patients lose weight due to a hormonal reduction of the appetite.

How much weight can I expect to lose with the sleeve surgery?

In average, the patients lose 25 to 40% of the total weight with this surgery. Even though these values vary a lot, depending also on the adhesion of the patient to the multidisciplinary treatment, diet, amount of physical activity, control of the anxiety and compulsions.
