Is weight loss surgery right for me?

Patients who meet certain criteria can benefit greatly from weight loss surgery. Candidates must have a Body Mass Index (BMI) of 40 or greater (about 100 pounds over ideal body weight) or BMI of 35 to 39.9 with a significant obesity-related condition such as diabetes, high blood pressure, heart problems, sleep apnea, or reflux disease. To calculate your BMI, use the calculator below. For a list of other criteria, please see our Frequently Asked Questions.

Bariatric surgery or weight loss surgery is the only option today that effectively treats morbid obesity in people for whom more conservative measures such as diet, exercise, and medications have failed. Bariatric surgery can be malabsorptive and/or restrictive. Our surgeons perform the Roux-en-Y gastric bypass (RGB) procedure and the LAP-BAND® procedure.

What is Roux-en-Y gastric bypass (RYGB) surgery?

The Roux-en-Y gastric bypass (RYGB) is a surgical procedure that alters the process of digestion. This procedure is both malabsorptive and restrictive.

It is malabsorptive because the procedure involves bypassing part of the small bowel resulting in fewer calories and nutrients being absorbed. It is restrictive because it involves creating a small stomach pouch that restricts the amount of food that can be eaten at one time. This surgery can result in two-thirds of extra weight loss within two years. While malabsorptive procedures are more effective in causing excess weight to be lost than procedures that are solely restrictive, they also carry more risk for nutritional deficiencies.

Dr. Vadim Sherman explains the
Roux-en-Y gastric bypass procedure.

What is the gastric sleeve?

The Gastric Sleeve (Sleeve Gastrectomy) surgery promotes weight loss by removing three-quarters of the stomach (the new stomach looks like a tube). The size of the stomach is reduced by 75 percent, and the stomach holds approximately two to five ounces. This promotes a feeling of fullness with smaller amounts of food, allowing reduced overall daily caloric intake. "Dumping Syndrome" is not as common with the Gastric Sleeve, and there is minimal nutrient malabsorption after surgery.

What is gastric banding?

Our surgeons also perform the LAP-BAND® procedure, sometimes called adjustable gastric banding. This procedure is solely restrictive and does not involve any stapling or re-routing of the gastrointestinal tract. This safe and minimally invasive bariatric procedure promotes weight loss through reduced food intake. In addition to the silicone ring, tubing is connected to an access port, which will be placed beneath the skin during surgery. This allows the surgeon to increase or reduce the size of the ring to better promote successful weight loss.
