Gastric bypass surgery restricts the amount of food you can eat and limits the body’s ability to absorb calories. It is the most frequently performed bariatric surgery worldwide.
At the University of Maryland (UM) Center for Weight Management and Wellness, our surgeon has more than 15 years of experience in performing gastric bypass surgeries.
During a gastric bypass, the surgeon:
- Creates a small pouch from the top part of the stomach, with the rest of the stomach sealed off.
- Divides the small intestine and connects the lower end to the newly created small stomach pouch.
The procedure bypasses most of the stomach and the upper small intestine, which is where some calories from food are absorbed. Gastric bypass helps weight loss because:
- The small stomach pouch limits the amount of food that you can eat.
- The shorter digestive path from stomach to small intestine reduces the amount of calories that your body can absorb.
- Rerouting the food stream causes changes in gut hormones to suppress your appetite, control blood sugar and help you feel fuller longer.
Also known as Roux-en-Y, gastric bypass is the gold standard procedure for weight loss surgery. That means that medical experts consider gastric bypass as the most successful surgery for total weight loss and long-term maintenance with the lowest risk of complications.
Advantages of gastric bypass include:
- Average weight loss of 60 to 80 percent of excess body weight within one year after surgery
- Generally higher average excess weight loss than in patients who have had restrictive surgeries such as sleeve gastrectomy and gastric banding
- Less weight regain, an average of 10 to 13 percent after 10 to 14 years, according to medical studies
- According to a study of 500 patients in 2000, improvement or resolution of 96 percent of the associated health conditions that were studied:
- Back pain
- High blood pressure
- Sleep apnea
- Type 2 diabetes

Our surgeon uses only the laparoscopic approach for gastric bypass surgery because of its many advantages. The procedure enables the surgeon to perform many of the same procedures as in traditional, open surgery. The advantages of laparoscopic surgery include:
- Less pain and reduced need for pain medication
- Less risk of wound infection
- Quicker recovery and return to daily activities
- Several small incisions rather than a large one
- Shorter hospital stays
Gastric bypass helps people who cannot lose a large amount of weight and maintain the loss through diet, exercise and other lifestyle changes. It can be a weight loss option for adults who are:
- Either approximately 75 pounds overweight with a major obesity-related health problem such as:
- Heart disease
- Sleep apnea
- Type 2 diabetes
- Or greater than 100 pounds overweight without any other complications
