Weight-Loss Surgery
Weight-Loss Surgery Options

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:
