Recovery after the gastric bypass procedure usually involves a three-day hospital stay for patients. Gastric bypass patients are typically able to return to work within three weeks of the procedure. Because the gastric bypass procedure shortens the digestive process and reduces the body’s ability to extract calories and nutrients from food, vigilance about nutrition and vitamin supplements will become a lifelong necessity following the gastric bypass weight loss surgery.

Gastric Bypass Results

Gastric bypass surgery patients generally lose 75-80% of their excess body weight within two years of the procedure. The most dramatic weight loss occurs during the first six to eight months after undergoing gastric bypass.
