How Much Weight can I Expect to Lose?

That depends on the procedure and the individual. With the adjustable gastric banding procedure, weight loss progresses steadily over a 2 to 3 year period and then stabilises. The final result could be approximately half of the patient’s excess weight. After four years, studies show the level of weight loss is equal to that achieved by gastric bypass surgery.

After interventional gastric surgery, such as a sleeve gastrectomy, even more excess weight loss could be expected, but it generally levels off in one to two years. A regain of up to 10 percent of your excess body weight is common.
