Pediatric Gastroenterology and Nutrition Services

Pediatric Gastroenterology and Nutrition Services

If your child has a digestive disorder, a liver condition or a nutritional problem, a pediatric gastroenterologist has the specialized skills needed to provide comprehensive care.

Pediatric gastroenterologists treat children from birth through the teen years. Because childhood digestive, liver and nutrition problems are often quite different from those seen in adults, it's important to see gastroenterologists who have made pediatric care the core of their medical practice.

Our experienced UC Irvine Health pediatric gastroenterology team provides timely, patient-centered care for conditions ranging from acute abdominal pain to food allergies, inflammatory bowel disease, liver disease and more.

To make a priority appointment, call us today at 714-581-4401.


The UC Irvine Health pediatric gastroenterology team is experienced at diagnosing and treating digestive disorders, liver conditions and nutritional problems in children of all ages.

Our team is led by Phyllis Agran, MD, a board-certified, fellowship-trained pediatric gastroenterologist with more than 35 years of experience delivering patient-centered care to Orange County children and their families.

Advanced Care

Children are not small adults. They have unique medical needs and they often express their concerns differently than adults do. It often requires specialized expertise to make an accurate diagnosis.

Our UC Irvine Health team has long experience in the diagnosis and management of gastrointestinal disorders and liver disease. We use specialized equipment such as endoscopes to examine the inside of the digestive tract or gather tissue samples (biopsies).

Coordinated Care

To ensure that your child receives comprehensive care, we work closely with other specialists as needed, including radiologists, anesthesiologists, endocrinologists, neurologists, developmental pediatricians and pediatric cardiologists.

Our team approach also includes good communication with the child’s family members and primary care pediatrician.

In addition, we collaborate with registered pediatric dietitians and occupational and physical therapists. 

We also believe an important part of caring for a child's health is to help address any needs the child and family may have for additional community resources or services.
