Full Answer

Gastric sleeve surgery is most appropriate for individuals who are at least 100 pounds over their ideal weight, with a body mass index, or BMI, of 40 or more, according to WebMD. Obese patients who are too heavy for gastric bypass surgery often find the sleeve gastrectomy to be a good alternative. It is also sometimes used as a preliminary weight reduction method for patients who will eventually have duodenal switch surgery once they achieve a lower weight.

The permanent and irreversible gastric sleeve surgery is performed either through a large abdominal incision or laparoscopically, explains WebMD. Over half of the stomach is removed and a tube, or sleeve, the size of a banana remains. Patients can suffer from nutritional deficiencies after the procedure due to malabsorption of vitamins and minerals, leading to anemia or osteoporosis. Surgical risks include infection at the site of the incision or in the abdominal cavity, known as peritonitis. Pulmonary embolisms are possible, and some patients develop gallstones after the procedure.
