Surgery is usually a last resort for patients who are dangerously obese and have failed other weight reduction strategies.

Liposuction for Obesity
This procedure removes fat cells in specific areas of the body. Most of these procedures are performed on parts of the body that have high concentrations of fat. This includes the buttocks, thighs, knees, and abdomen. Treatment may result in skin folds.

Gastric Stapling for Obesity
This surgical procedure involves stapling a part of the stomach, in order to reduce the size of the stomach. Dumping syndrome is a potential complication.

Gastric Bypass for Obesity
There are several different surgical approaches, but the most common one (Roux-en-Y) involves the creation of a small stomach pouch that bypasses a portion of the upper intestine. When food is swallowed it travels from a smaller than normal stomach directly into the lower intestine. This bypass has the effect of restricting the amount of calories that can be absorbed by the small intestine. Dumping syndrome is a potential complication.
