Pitt Scientists Demonstrate Positive Effects of Physical Activity in Patients and Identify Predictors of Satisfaction after Bariatric Surgery


THE PHILLY VOICE — In today’s issue of the Annals of Surgery, epidemiologists from the University of Pittsburgh published two separate analyses that could help guide clinicians and policymakers in counseling bariatric surgery patients to improve their quality of life for many years to come.
