Gastroenterology / Hepatology / Nutrition

The Pediatric Gastroenterology, Hepatology and Nutrition Section offers diagnosis and treatment of gastrointestinal, liver, and nutritional disorders for infants, children, and adolescents. Among the common disorders we treats are chronic abdominal pain, diarrhea, constipation, and vomiting, or gastroesophageal reflux disease.

We also have broad experience with less common disorders including:

  • Gastrointestinal bleeding
  • Inflammatory bowel disease (Crohn’s Disease and Ulcerative Colitis)
  • Celiac disease and other forms of chronic diarrhea and malabsorption
  • Eosinophil-related gastrointestinal disorders, such as, allergic bowel disease, parasitic infection, eosinophilic gastroenteritis, and eosinophilic esophagitis
  • Acute and chronic liver disease, including viral hepatitis, autoimmune hepatitis, drug-induced hepatitis
  • Biliary tract diseases
  • Short-bowel syndrome due to necrotizing enterocolitis or congenital malformations
  • Complex nutritional problems requiring total parenteral nutrition and specialized tube feedings
  • Inborn errors of metabolism that affect the liver and other parts of the gastrointestinal tract
