Sleeve gastrectomy induces weight loss by restricting food intake. With this procedure, the surgeon removes approximately 75-80 percent of the stomach laparoscopically so that the stomach takes the shape of a tube or “sleeve”.
Studies have shown that Ghrelin, a hunger regulating hormone, is reduced following this operation. This is due to removal of a segment of the stomach which is responsible for Ghrelin production. This results in superior weight loss due to appetite suppression. Most patients lose 60-70% of their excess body weight following sleeve gastrectomy.
Unlike gastric bypass there is no Malabsorptive component to this operation, so the possibility of protein and vitamin malnutrition is much less. The sleeve also does not involve cutting or sewing the small intestine and therefore minimizes potential future complications with the intestines. Some patients with Gastroesophageal reflux disease may have worsening of their symptoms postop.
Sleeve Gastrectomy is Associated with improvement, or full resolution of all of the following:
- High Blood Pressure
- Sleep Apnea
- Arthritic Pain
- Urinary Incontinence
Weight Loss Surgery has also been shown to decrease the risk of developing certain cancers such as Ovarian, Breast, Uterine and Colon Cancer.
There are risks to sleeve gastrectomy including leaks, bleeding, stricture and anesthesia-related risks; however, these risks are low and are weighed against the benefits of the surgery. The benefits are strongly felt to outweigh the risks in the large majority of patients, but surgery is not for everyone. Please attend one of our bariatric seminars for more detailed information.
