Weight Loss Research at UPMC Bariatric Surgery Center

Researchers at the UPMC Bariatric Surgery Center of Excellence continually investigate the correlation between excess weight and various health risks.

Studies about the mechanics of metabolism and the emotional components of eating, have important implications for people who are trying to lose weight.

In addition, as bariatric surgery for weight loss continues to increase in popularity, it's important to understand the long-term effects of these procedures.

Our research studies range from laboratory bench science to clinical outcomes. We are pioneers in many areas of obesity research that directly impacts the health and well-being of the community.

Research at Magee-Womens Hospital of UPMC

The popularity of bariatric surgery procedures is on the rise. The American Society of Metabolic and Bariatric Surgery reports that the number of bariatric surgical procedures increased from about 16,000 in the early 1990s to 220,000 in 2008.

As the number of procedures increases, so does the need for research to:

  • Better understand the long-term effects of bariatric surgery
  • Discover the best way to care for patients before, during, and after a bariatric surgery procedure

What we’re doing

The surgeons of the Minimally Invasive Bariatric and General Surgery (MIBGS) Program at Magee-Women’s Hospital of UPMC are currently researching the effects and outcomes of bariatric surgery, as well as the biochemical mechanisms of obesity.

Using the vast research resources within the University of Pittsburgh, MIBGS surgeons are able to participate and excel in numerous national and international research studies and clinical trials.

Our surgeons use a multidisciplinary, clinical approach to research, collaborating with:

  • Pulmonologists
  • Cardiologists
  • Endocrinologists
  • Psychologists
  • Nutritionists
  • Exercise specialists

Our motivation to offer the highest quality and most effective treatments for obesity — and its associated medical conditions — is wonderfully supported by the dedication and participation of our patients.​
