Description of Research Expertise

Diva D. De León, M.D. is an Assistant Professor of Pediatrics and a Pediatric Endocrinologist in the Division of Endocrinology and Diabetes at The Children's Hospital of Philadelphia. Dr. De León research interest focuses on congenital and acquired forms of hyperinsulinemic hypoglycemia. She is particularly interested in the role that alterations of the entero-insular axis may play in the pathophysiology of these disorders.

Description of Clinical Expertise

Dr. De León specializes in the diagnosis and management of monogenic disorders of insulin regulation resulting in diabetes and hypoglycemia, and general endocrinologic problems. Dr. De León predominantly cares for children with congenital and acquired forms of hyperinsulinemic hypoglycemia.
