    Overview All infants and children experience digestive upsets at some point and in most cases, their primary care physician can help them get better. But when disorders of the digestive system are severe, persistent or complex, families may be referred to a specialist in children's digestive disorders. This kind of specialist is known as a pediatric gastroenterologist. At Stony Brook Children's, the Division of Pediatric Gastroenterology and Nutrition serves Suffolk County as a referral center for complex cases. We specialize in diagnosis and long-term care for children with gastrointestinal, liver, pancreatic and nutritional disorders including including celiac disease at our own Celiac and Gluten Sensitivity Center, the first comprehensive center on Long Island to address celiac and gluten issues for children and teens.

    Committed to delivering comprehensive, collaborative care, our gastroenterology department conducts about 5,000 outpatient visits, and 750 inpatient consults and endoscopies per year. The Division is actively involved in clinical and basic science research in the field of pediatric gastroenterology and nutrition. We also teach medical students, residents and fellows affiliated with the Stony Brook University School of Medicine.

    Our Team Our team of board certified pediatric gastroenterologists is complemented by highly trained nurse practitioners, a registered dietitian, and Inflammatory Bowel Disease (IBD) and celiac educators. We work closely with our state-of-the-art endoscopy unit staff as well as motility laboratory staff. Pediatric anesthesiologists provide anesthesia for all endoscopy patients - a minimally invasive procedure that is used to diagnose a number of gastrointestinal issues including celiac disease. Together, we provide multidisciplinary care drawing upon all the resources and specialists of our academic medical center as needed, including pediatric surgery, pediatric radiology, pediatric anesthesia, pediatric intensive care, and more.
