Roughly 37 million more Americans are now eligible for weight loss surgery with the Lap-Band adjustable gastric banding system, Allergan (Irvine, California) reported. The FDA has approved the expanded use of Allergan's Lap-Band system for adults with obesity who have failed more conservative weight reduction alternatives, such as diet and exercise and pharmacotherapy, and have a body mass index (BMI) of 30 to 40 and at least one obesity related co-morbid condition.
