Weight loss after laparoscopic adjustable gastric banding is somewhat difficult to quantify because weight loss is not as pronounced as other surgical interventions. With certain procedures, especially malaborption procedures, there is a large and rapid decrease in weight that stops decreasing after a period of time. With adjustable gastric banding, the weight loss is usually about 50% of the excess body weight and BMI decreases about 25 percent. Over time, individuals may actually experience a greater degree of weight loss with more band adjustments. Full benefit may not be realized for up to ten years after the surgery but noticeable weight loss occurs much earlier. Weight loss is, at best, in the same range as a “stomach stapling” approach (vertical banded gastroplasty).
Several obesity-related illnesses may improve or be fully corrected after adjustable gastric banding. As one might expect, the degree to which these diseases improve correlates with the degree of weight loss. In other words, the more weight that is lost, the better off people are in terms of obesity-related diseases. Some studies have shown that half the people undergoing adjustable gastric banding experience a remission of their Type 2 diabetes mellitus. Remission means that the diabetes was fully controlled without the need for medication. Diabetes remission rates for other bariatric procedures are often higher than 50 percent, however.

Other Information
Adjustable gastric banding is a surgical operation intended for weight loss in obese people with a body mass index of at least 35 (obesity starts at BMI 30).
It is best done laparoscopically under general anesthesia. Usually, it takes about one hour. It consists in inserting a hollow plastic band around the stomach. This band is connected by a tubulure to a small box implanted in the abdominal wall. You can constrict the band by filling the box with physiologic serum. Band constriction has a restrictive effect on gastric filling capacity and forces the patient to lower his food intake and it can be modulated by emptying or filling the box with a percutaneous needle. This operation is practised only if the patient is highly motivated for changing his/her eating habits and after a psychiatric assessment.

Average excess weight loss at five years is 48-74 percent after gastric bypass and 50-60 percent after vertical banded gastroplasty -2004
