Gastric sleeve surgery, or sleeve gastrectomy, is a type of weight loss surgery that involves the removal of a large part of the stomach. After the surgery, the person feels full after eating a small amount of food.
The surgery also makes people feel less hungry because a smaller stomach will produce lower levels of a hormone called ghrelin, which causes hunger.
Recommended for people who are very obese, or for those who have health problems caused by obesity.
This procedure should only be considered after trying alternatives.The first step is usually to try changes to your diet as well as your daily activity and exercise. Some medications also help people lose weight. Surgery is usually thought about only after these other options have been tried.
Losing weight after gastric sleeve surgery can help reduce problems with type 2 diabetes, asthma episodes, blood pressure, and can help improve heart health.
