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.
– During the laparoscopic sleeve gastrectomy the nerves of the stomach and pylorus are not altered, preserving the function of the stomach.
– The rest of the gastrointestinal tract anatomy is not altered, so the food ingested follows the normal course. This results in less chance of developing lack of vitamins and minerals and dumping syndrome.
– The procedure decreases significantly the hunger by removing the part of the stomach that produces the main stimulating hormones.
– Fewer clinic follow-ups than the laparoscopic stomach band, since there is no need for band size adjustments.
