A gastric sleeve, also known as laparoscopic sleeve gastrectomy or sleeve gastrectomy, limits the amount of food the stomach can hold at one time. About 75–85% of the stomach is removed.
The remaining part is sewn into a tube shape, and the way your intestines absorb calories and nutrients does not change. The operation is laparoscopic (closed) and minimally invasive: very small incisions are made in your abdomen, and a slim instrument with a tiny camera and light is inserted through them. The surgeon follows the planned surgical steps on a monitor. Because the incisions are so small, scarring is minimal.
The idea is that patients feel full after eating much less. The operation also affects your hormones, so you stay full for longer. This has a direct effect on your eating habits and lifestyle.
