The gastric sleeve is a surgical procedure that involves the removal of a large portion of the stomach (usually around 70-85%), leaving a tube-like structure or “sleeve.” This drastically reduces the stomach's capacity, limiting food intake and making the patient feel fuller faster.

• Also known as: Sleeve gastrectomy, vertical sleeve gastrectomy (VSG).

• Type of procedure: Laparoscopic (minimally invasive).

• Purpose: Weight loss by restricting the amount of food the stomach can hold
