Gastric Bypass vs Lap Band

Despite the common goal of long-term weight loss between gastric bypass vs lap band, both types of bariatric surgery procedures are significantly different. The most notable difference between the surgical weight loss options is that gastric bypass is a more invasive surgery that reroutes your digestive tract to reduce food intake and absorption of calories (nutrients).

In contrast, lap band surgery is a purely restrictive procedure that doesn’t surgically alter your digestive tract. Instead, the lap band procedure promotes weight loss by wrapping an inflatable gastric band around the top part of your stomach, which creates a small pouch (1-2 oz).

Difference Between Gastric Bypass vs Lap Band

Although both procedures are highly effective at achieving weight loss, gastric bypass remains the most commonly performed type of bariatric surgery worldwide. About 160,000 gastric bypass surgeries are performed each year in the United States, alone.
