Testing for Specific Conditions

Your pediatrician will refer you to a Catholic Health pediatric gastroenterologist if your child has trouble with constipation, diarrhea, poor weight gain or other gastrointestinal issues that require specialized care. Our pediatric surgeons also offer clinical excellence in gastroenterology surgery, using minimally invasive procedures whenever possible.

Our pediatric gastroenterologists work alongside pediatric anesthesiologists to ensure a child is comfortable during testing to diagnose gastrointestinal issues. Diagnostic procedures include upper endoscopy and lower endoscopy.
