Gastric Sleeve is a restrictive surgery, which is performed trough laparoscopic surgery or minimally invasive surgery, it is known as restrictive because the size of the stomach is reduced by approximately 70%, this way the stomach no longer has the same capacity. Obesity patients need to fill their stomachs to get a message that allows them to realize that they have already eaten enough.
Gastric Sleeve works apart from the restrictive mechanism, by changes in ghrelin which is a hormone that regulates appetite.
By removing 70% of the stomach, the desire to eat decreases and the patient will feel full with little food, which makes it possible for the patient to take an appropriate nutritional regimen, seeing as weight loss between the next 12 and 18 months
