Gastroenterology (GI)

There’s no place like CHOC Children’s for the diagnosis and treatment of children with gastrointestinal illnesses and diseases. Our gastroenterology team is committed to offering patients the very latest treatments in an environment dedicated to patient- and family-centered care.

Our physicians and other health care professionals are specially trained to treat pediatric gastroenterology patients and work closely with each child’s care team to create the best treatment plan possible. This team includes the patient, parent or guardian, subspecialist and primary care provider. Each patient’s unique treatment plan takes into consideration the child’s present and future medical and emotional needs, the family’s preferences, as well as social and ethnic considerations.

A Team Approach to Hope and Healing

Gastroenterology is the medical specialty dealing with digestive illnesses and diseases, including problems with the esophagus and stomach, liver and pancreas, small intestine and colon (large intestine). Because we specialize in pediatric gastroenterology, we are able to provide our patients with the most innovative, comprehensive and clinically advanced care available. Improving a child’s quality of life and making it possible for them to participate in school and family activities as quickly and as much as possible are always an important goal for our treatment teams.

At CHOC Children’s, we understand that treating painful or worrisome gastrointestinal disorders requires the talents of more than our expert gastroenterologists. We have a dietitian and psychologist who work exclusively with our gastroenterology patients. They provide our patients the dietary, emotional and psychosocial support they need to cope with their symptoms and ultimately find relief.

State-of-the-art Diagnostics

Some patients may need to undergo an extensive diagnostic evaluation beyond a physical examination and medical history. These tests can laboratory tests, imaging tests, and/or endoscopic procedures. At CHOC Children’s we are proud to feature a wide array of some of the most advanced diagnostics available. Learn more about gastrointestinal disorder diagnostics at CHOC.
