There are two types of surgical procedures that can promote weight loss.

  • Restrictive: These procedures limit the amount of food you can eat at one time, either by removing or closing off a portion of the stomach
  • Malabsorptive: These procedures remove or bypass parts of the small intestine, where the majority of calories are absorbed by the body.

Weight loss surgery may incorporate one or both types of procedures to help you lose weight. The risks and long-term effects of weight loss surgery will depend, in part, on which strategies are used. Restrictive procedures, such as lap band surgery, will make it difficult to overeat, but doesn’t drastically limit the types of foods you can eat. Gastric bypass, which is a combination of restrictive and malabsorptive procedures, limits how much you can eat and requires patients to avoid foods that are high in fat or sugar.


Weight loss surgery helps people to change their diet and eating habits, which often results in a dramatic weight loss. Most patients continue to lose weight for up to two years after their surgery and are able to maintain a healthy weight longer than people who lose weight through diet and exercise*.

As a result of losing weight, patients who suffer from obesity-related medical problems will often experience relief from their symptoms after weight loss surgery*. Even patients with chronic conditions, such as diabetes, have seen an improvement in their well being and a reduced need for medication after having surgery.


If you are a man who is 100 or more pounds overweight, or a woman who is 80 or more pounds overweight, you may be a candidate for weight loss surgery. You may also be a candidate if you are less overweight but suffer from at least one obesity-related medical condition, such as diabetes or sleep apnea. As of 2011, the FDA approved the use of lap-band surgery, a restrictive weight loss surgery, for people with a body-mass index of 30 or higher who also have one co-morbdity.

Weight is not the only factor to consider before choosing weight loss surgery. A candidate should also have tried to lose weight in the past without surgery and be able to demonstrate that they are willing and able to make long-term changes to their diet and exercise habits.
