How Gastric Sleeve Surgery Helps You Lose Weight?
Gastric sleeve surgery or sleeve gastrectomy is the only bariatric procedure that will reduce your appetite as well as the amount that you need to eat to feel full. If you are considering a sleeve gastrectomy, you should make sure you understand what the procedure involves as it is not reversible.
Gastric sleeve surgery involves the removal of a large section of your stomach. Reducing the size of your stomach will restrict the amount you can eat. It will also reduce your appetite by decreasing the production of appetite stimulating hormones in your stomach.
The sleeve gastrectomy is usually performed as a laparoscopic procedure, through four or five keyhole incisions. The operation will take one to two hours and requires a general anaesthetic. A large part of your stomach will be removed. The remaining section will be shaped into a sleeve or tube about the size of a banana and sealed using staples. You will need to stay in hospital for two to three nights after the procedure and it will be two or three weeks before you are fully recovered.
Pros and Cons
A sleeve gastrectomy can help you to lose weight by restricting the amount you can eat and reducing your appetite. Like a gastric bypass or band, gastric sleeve surgery restricts the amount of food that you can eat by reducing the size of your stomach so that you feel full faster. However, the removal of a large part of your stomach also reduces the amount of appetite stimulating hormones it is producing, which can help you to feel less hungry. Most people who follow the recommended diet will lose 50-60% of their excess weight after the gastric sleeve procedure.
Gastric sleeve surgery does not alter the route that food takes through your digestive system and the remaining part of the stomach retains its ability to start the digestive process, so you will still be able to digest and absorb food normally. Dumping syndrome is less common than with a gastric bypass, but there is still a chance that it could happen as the food will be passing through your small stomach sleeve faster than usual.
The risk of complications during gastric sleeve surgery is slightly lower than for a gastric bypass, but higher than for a gastric band. Potential complications include narrowing of the sleeve and problems with the staples that hold it closed after the surgery. The sleeve gastrectomy is not a reversible procedure since part of the stomach is removed, but there is a chance that the remain section will stretch over time. This will reduce the restriction and increase your appetite, which could make it more difficult to keep your weight down.
