What is a sleeve gastrectomy?

The sleeve gastrectomy has quickly become the most popular weight-loss surgery performed nationwide. Named after the shape the stomach resembles at the conclusion of the procedure, about 80 to 85 percent off the stomach is permanently removed, leaving patients with 2 to 3 ounces of capacity. Patients usually spend one night in the hospital.

How does the surgery help bariatric patients?

The sleeve's main cause of weight loss is through restriction. Patients become full shortly after eating a small portion. This limits the amount of calories consumed in a given day. There are also metabolic effects of the surgery. The upper part of the stomach that is removed makes a hormone that helps to regulate appetite. After surgery, the quantity of the hormone is significantly lower, reducing appetite. Additionally, the new stomach empties in the intestine much more rapidly. This causes the release of hormones that help to resolve medical problems such as diabetes, high blood pressure and high cholesterol.

How much weight do patients lose with the sleeve gastrectomy?

Overall, patients can expect to lose on average 55 percent of their excess weight. Often times they stop or considerably reduce the amount of medications they are taking, including their diabetes medications.

The effects of weight-loss surgery are enhanced by the effort of the patient. The ability to maintain their weight loss will depend on the dedication to a healthy lifestyle, diet and exercise regimen. As with any surgery, there are potential complications. However, the sleeve has been shown to be safer than other weight-loss surgeries.

Do you recommend the sleeve gastrectomy?

The sleeve gastrectomy is an effective and safe weight-loss surgery. In the past seven years, sleeve procedures have ballooned due to consistent, reproducible weight loss results and long-term, metabolic effects.
