Surgical procedures for weight loss can be divided into three categories.

  • Restrictive
  • Malabsorptive
  • Combined

Restrictive procedures are those that limit the amount of food that will fit in the stomach. As a result it takes a smaller amount of food before the stomach feels full, and sends a signal to the brain that you're not hungry. This allows a person to eat less, while not having to experience the hunger pains associated with dieting. The most common restrictive operation done today is the Lap-Band.

Malabsorptive operations work by rerouting the intestines, in an effort to limit the absorption of calories. This is a much bigger operation, but can be very successful in select situations. It is accompanied by a higher complication rate. The most common malabsorptive procedure done today is the Bilopancreatic Diversion. It is done much less commonly in the United States, and is not done by every surgeon. (Dr. Farkas does not generally do this operation in his practice.)

Combined operations, as you can guess, incorporate some of each of the above two methods. That is, they have some degree of restriction, and some degree of malabsorption. The most common of these operations is the Roux-en-Y Gastric Bypass, which is the most common weight loss operation in the United States today.
