Gastric sleeve surgery, also known as laparoscopic sleeve gastrectomy it is a very popular weight loss procedure and reduces the size of the stomach from about 32 ounces (a quart) to about 8-10 ounces (the size of a banana).

The Sleeve Gastrectomy works by two different mechanisms, the first is restriction; which decreases the amount of solid food intake and the second is a “chemical/hormonal” effect. Which can significantly reduces a person’s appetite for a prolonged period of time after the surgery. The reduction in appetite supports ongoing weight loss; it’s much easier to reduce food intake when a person doesn’t feel hungry. Bariatric patients are often amazed by this aspect of the surgery. The reduction in appetite is one of the factors that makes the sleeve a very impactful bariatric option for obesity.

The Gastric Sleeve is non reversible as it permanently reduces the stomach size,  because it is designed to help our patients to feel  fuller, thus eliminating the desire to eat as much, ultimately lose weight and achieving a healthy BMI.
