You may lose up to 80 percent of excess body weight within five years. Gastric bypass may also treat acid reflux disorder because the acid-producing part of the stomach is separated from the esophagus.
During laparoscopic gastric bypass surgery:
- Your surgeon forms your stomach into a smaller pouch.
- The surgeon attaches a section of the small intestine directly to the pouch, allowing food to bypass a portion of the small intestine that absorbs calories and nutrients.
