What is the gastric sleeve and how does it work?

Gastric sleeve (also called sleeve gastrectomy) is a bariatric surgery in which approximately 75-80 percent of the stomach is removed, giving it a tube-like shape or «sleeve.» The reduced stomach limits the amount of food you can consume and decreases the production of ghrelin, the hunger hormone, which helps you eat less without feeling as much hunger.

Results vary depending on each patient, but on average patients lose between 60% and 70% of their excess weight within the first 18 months. For example, if a person has 40 kg of excess weight, they can expect to lose between 24 and 28 kg. The best results are achieved by combining surgery with lifestyle changes, healthy eating, and physical activity.

Like any surgery, gastric sleeve involves certain risks. The most common include nausea, gastroesophageal reflux, and, in rare cases, leakage at the stapling line.
