Adjustable Gastric Banding (also known as Lap Band) is a purely restrictive surgical procedure in which a small band is placed around the uppermost part of the stomach. This band divides the stomach into two portions: one small and one larger portion. Since the stomach is divided into smaller parts, most of our Las Vegas Lap Band surgery clients feel full faster. As the name indicates, the band is adjustable. So if the rate of weight loss is not acceptable, the band can be adjusted. Food digestion happens through normal digestion.
