The Sleeve Gastrectomy works by two different mechanisms, the first is restriction and the second is a “chemical/hormonal” effect. The Sleeve Gastrectomy reduces the size of the stomach from about 32 ounces (a quart) to about 4 ounces (the size of a banana). This restricts the amount of food a person can consume (similar to a band); however the surgery has an additional effect. This additional effect (what we call the “chemical/hormonal” effect) is to significantly reduce a person’s appetite for a prolonged period of time after the surgery, anywhere from one to three years.

The reduction in appetite supports ongoing weight loss as it is much easier to keep food intake to a minimum when a person doesn’t feel hungry. Bariatric patients (who have struggled with their weight and appetite, in many cases, for their entire lives) are often amazed by this aspect of the surgery. This reduction in appetite is one of the main differences between the sleeve and the band.

The Sleeve Gastrectomy is a permanent procedure; once the portion of your stomach is removed, it cannot be ‘undone’. The gastric sleeve has been around since the 1970s and was originally part of a 2-part surgery called the duodenal switch. Patients were having provocative results in rapid weight loss on part ‘1’ of the duodenal switch and were not going back for the 2nd part of the surgery. After years of study and validating the sustained weight loss results, the gastric sleeve was approved as a stand-alone bariatric procedure. The advent of the gastric sleeve, as an insurance-approved procedure for weight loss surgery, took place in early 2010. Our office has offered the gastric sleeve since being approved by COE for use in weight loss surgery in 2010.
