Bariatric Surgery for Weight Loss
If you need to lose more than 100 pounds, and diet and exercise haven’t worked, bariatric surgery can be an effective tool for treating obesity and its related health complications.
At UPMC's Bariatric Surgery Center of Excellence, our surgeons perform a spectrum of weight loss procedures. They'll work with you to develop a personalized weight loss plan and determine the best surgical option for you.

Malabsorptive and Revision Bariatric Procedures
- Reduce the stomach size by two-thirds, but do not severely restrict food intake.
- Reduce the body’s ability to absorb calories and nutrients from food.
- Create much more intestinal bypass and therefore more malabsorption.
- Reduce the size of the stomach to restrict food intake.
- Are for people who have already had bariatric surgery and either had complications or didn't successfully lose weight.
Depending on your health, the type of bariatric procedure you're having, and other factors, surgeons will use one of the following surgical methods:
- Minimally invasive (laparoscopic) surgery — The surgeon inserts a laparoscope through several, 1/4- to 1/2-inch incisions to access the stomach and intestines.
- Traditional open baritric surgery — The surgeon makes a 10- to 12-inch incision to access the stomach and intestines.
- Single-incision techniques — The surgeon uses a single incision, reducing future scarring and potentially accelerating healing.
