Sleeve gastrectomy is a surgical intervention designed to promote weight loss by restricting food intake. Typically performed using laparoscopic techniques, this procedure involves the removal of approximately 75% of the stomach. As a result, the remaining portion of the stomach assumes a tubular or "sleeve" shape, which significantly reduces its capacity to hold food. This method has become a widely accepted and effective option for weight loss in individuals with a body mass index (BMI) exceeding forty.

Sleeve gastrectomy, also known as gastric sleeve surgery, is a weight loss procedure that entails reducing the stomach's size. In this operation, a significant portion of the stomach is removed, leaving a sleeve-shaped section approximately the size of a banana. This alteration decreases the stomach's capacity to hold food, enabling patients to feel satiated more quickly and consume less. Gastric sleeve surgery in India has proven to be effective in assisting patients with weight loss and enhancing their overall health.
