resulting in significant weight loss.
Over 200,000 people have bariatric surgery
each year in the United States.

◦ Decreases how food is absorbed
◦ Stomach, duodenum, and upper intestine have no
contact with food


◦ Second most common weight loss surgery
◦ A band restricts the opening from throat to stomach
creating a pouch


switch (BPD)
◦ Accounts for >5% of all weight loss surgery
◦ Removes large part of stomach
◦ Reroutes food away from small intestine
