Weight-loss surgery is a safe and effective treatment option for those affected by morbid obesity. Morbid obesity is defined as having a BMI of 40 or greater, or weighing more than 100 pounds over ideal body weight. In addition, a patient with a BMI of 35 or greater with one or more obesity-related diseases is considered to be a candidate for weight-loss surgery.

There is a great amount of importance and responsibility associated with choosing a weight-loss treatment option. Choosing which type of weight-loss surgery is right for you can be a difficult task. It is our goal to provide you with the education needed to guide you and your surgeon to make the appropriate treatment selection.

Remember, weight-loss surgery is not the “easy way out.” This treatment option is a tool that patients use to lose weight. Surgery is a resource to help you reduce weight while behavioral, physical and psychological changes are required for you to maintain a healthy quality of life. Continued positive weight-loss relies upon your desire and dedication to change your lifestyle with a proactive approach. The most commonly performed weight-loss surgeries include:

Roux-En-Y Gastric Bypass

Adjustable Gastric Banding (LapBand)

Sleeve Gastrectomy

Note: It is important to note that there are risks involved with weight-loss surgery, as well as any other surgical procedure. Before making a treatment decision, it is important to discuss these risks with your physician and/or surgeon.


You may not be familiar with the terms “Malabsorptive,” "Restrictive," "Laparoscopic" and “Open”. Prior to reading about the different surgeries, we have provided you with a brief description of some of the most commonly used terms when talking about weight-loss surgery.

Open vs. Laparoscopic

Procedures In each section, you will see the surgeries described as being performed “open” or “laparoscopic.” Although the laparoscopic procedure has increasingly gained in popularity and frequency, open procedures are still used in practice today.

"Open" - The open procedure involves a long incision that opens the abdomen, which provides the surgeon access to the abdominal cavity.

"Laparoscopic" - In laparoscopic surgery, a small video camera is inserted into the abdomen allowing the surgeon to conduct and view the procedure on a video monitor. Both camera and surgical instruments are inserted through multiple small incisions (0.5-1.2cm) made in the abdominal wall.

Malabsorptive vs. Restrictive

Throughout this section, the surgeries will be described as “malabsorptive,” “restrictive” or a combination of the two. Depending on the type of procedure that is determined to be best for your needs, each requires different lifestyle changes.

"Malabsorptive" - Malabsorptive procedures alter digestion, thus causing the food to be poorly digested and incompletely absorbed.

"Restrictive" - Restrictive procedures decrease food intake by creating a small upper stomach pouch to limit food intake.
