Gastric sleeve surgery is a type of weight-loss surgery. This surgery restricts your food intake, which leads to weight loss. You may lose from 50 to 90 pounds.
This surgery takes out the part of your stomach that curves outward, called the fundus. After the fundus is taken out, your surgeon will close the rest of your stomach into a tube shape that looks like a banana.
Bariatric surgery is a type of surgery to help you lose weight. It is a choice for some people who have obesity and have not been able to lose weight with other methods.
