The bariatric program at Saint Elizabeth offers three different weight loss surgery options: Laparoscopic Gastric Bypass, Laparoscopic Sleeve Gastrectomy, and the Lap-band® (adjustable gastric band). All three are restrictive, which means they reduce the size of the stomach to decrease food intake. The gastric bypass is a Malabsorptive procedure, which means part of the small intestine is bypassed to decrease calories absorbed from foods eaten. This is called a combination surgery since it is both a restrictive and malabsorptive procedure.

Here’s a summary of the three surgeries and some key differences:

Type	Restrictive	Restrictive	Combination

Food passes through band into main stomach.	Creates 1-2 ounce stapled stomach pouch. Bypasses the rest of the stomach plus a section of small intestine.
