Pediatric endocrinology is the study and treatment of disorders of the endocrine system of infants, children and adolescents. A pediatric endocrinologist is a pediatrician who treats children with diabetes, metabolism disorders, and other hormonal conditions. An endocrinologist treats diseases that result from an abnormality in the endocrine glands (glands which secrete hormones), such as diabetes, growth failure, early or late pubertal development, birth defects and thyroid disorders.
