Gastric sleeve surgery commonly known as vertical sleeve gastrectomy involves a removal of large portion of stomach leaving behind a banana-shaped sleeve that is closed with sleeves. This surgery causes favorable changes in gut hormones that suppress hunger, reduce appetite and improve satiety. Surgeons mostly perform this surgery using a laparoscopic method.
In this surgery about 80% of the stomach is removed, leaving the intestines entirely in place. The remaining stomach is formed into a vertical sleeve. Since the intestines are left intact, nutrient absorption is not reduced. It also limits the production of some appetite regulating hormones or other factors, which make you, feel less hungry. After surgery, the stomach will almost resemble a banana shape. Since most of the stomach is permanently removed the surgery cannot be reversed.
After surgery, patient will need to make lifelong changes in eating habits that include eating smaller portions.
Gastric sleeve surgery decreases the size of stomach, limiting the amount of food stomach can hold. Due to which most people feel full faster and continue to feel full for hours. The end result is reduction in the desire to eat and in the frequency of eating.
