Gastric sleeve (also called sleeve gastrectomy) is the most common weight loss procedure. With this operation, the surgeon removes part of the stomach and makes a tube or "sleeve" out of the rest of the stomach. The new, banana-shaped stomach is much smaller than the original stomach.
After the operation, a person will eat less, feel full sooner, and be less hungry. The gastric sleeve operation only changes the stomach. The gastric sleeve procedure is not reversible.
What happens during gastric sleeve surgery?
The keyhole surgery is done while you are under a general anaesthetic. Your surgeon will use a stapling device to create a small tube or 'sleeve' in your stomach, then remove the rest of your stomach. After surgery, your stomach will hold only about a tenth of what it did before.
The Gastric Sleeve Surgery is a Bariatric procedure that removes 75-80% of the stomach. It is now the most commonly performed bariatric procedure in worldwide.
Gastric sleeve surgery is best for people who have a BMI (body mass index) of at least 40. That means you’re 100 pounds or more over your ideal weight. Some people are too heavy for gastric bypass surgery, so it may be a good alternative.
