​Lurie Children’s Pediatric Surgeon First in Illinois Board-Certified in Obesity Medicine


Ann O’Connor, MD, an authority in the surgical care and treatment of obesity and obesity-related disorders in teens, recently became the only pediatric surgeon in Illinois certified by the American Board of Obesity Medicine.

Dr. O’Connor leads Lurie Children’s bariatric surgery program, which is the only program in the State of Illinois with expertise specifically dedicated to the treatment of adolescents and their unique medical, behavioral, nutritional and psychological needs.

Her 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.

When medical and behavioral weight loss programs have proved unsuccessful for severely obese teenagers, bariatric surgery can be an effective treatment, as it can resolve more than 80% of weight-related health issues.

Dr. O’Connor sees patients at Lurie Children’s at Northwestern Medicine Central DuPage Hospital Pediatric Outpatient Center.
