How much weight will I lose? Will the weight loss be quick?

The amount of weight you lose, and how fast you lose it, will depend on which weight-loss surgery is right for you. Patients who have laparoscopic adjustable gastric banding using the REALIZE™ or LAP-BAND® devices or those who have sleeve gastrectomy usually lose weight more slowly the first year than those who have gastric bypass surgery.

However, the total weight loss is comparable with each procedure if patients exercise and follow the recommended diet. A successful patient would be expected to lose up to 50 percent or more of his or her excess weight.
