Laparoscopic sleeve gastrectomy has become the most popular weight loss surgery due to its effectiveness and simpler procedure compared to gastric bypass. This surgery reduces the stomach size, leading to an average of 65% excess weight loss. It primarily works by restricting food intake and reducing hunger signals for up to two years. Unlike gastric bypass, it does not affect nutrient absorption, so all calories are absorbed as before. However, weight regain may occur slightly faster compared to gastric bypass.

How it Works
What is Sleeve Gastrectomy?
Sleeve gastrectomy gets its name from the tube-like shape of the remaining stomach after the majority of the organ is removed. The procedure is performed using five small incisions and a laparoscopic camera for precise visualization. Blood vessels along the left curvature of the stomach are sealed and divided, then a surgical stapler removes a large portion, leaving a small “sleeve” connecting the esophagus to the small intestine. This drastically reduces stomach volume, creating a feeling of fullness after just a few bites.
Although irreversible, the sleeve can be revised into a gastric bypass, SADI-S, or duodenal switch if necessary.
