When behavioral, lifestyle and non-surgical medical interventions fail, bariatric surgery can resolve up to 80 percent of obesity-induced medical conditions. Dr. O’Connor’s interest in surgical weight management in teens was sparked by her observations early in her career that many of her patients had medical and surgical problems stemming from obesity.
In addition to bariatric surgery, Dr. O’Connor has surgical expertise in the treatment of a variety of congenital and acquired diseases in the newborn, child and adolescent, including pediatric trauma and injury, congenital malformations, pediatric tumors and others.
Dr. O’Connor’s research focuses on the surgical management and outcomes of adolescents who undergo weight-loss surgery. Learn more about bariatric surgery for adolescents.
