Pediatric endocrinology (British: Paediatric) is a medical subspecialty dealing with variations of physical growth and sexual development in childhood, as well as diabetes and other disorders of the endocrine glands.
By age, pediatric endocrinologists, depending upon the age range of the patients they treat, care for patients from infancy to late adolescence and young adulthood.
By disease, the most common disease of the specialty is type 1 diabetes, which usually accounts for at least 50% of a typical clinical practice. The next most common problem is growth disorders, especially those amenable to growth hormone treatment. Pediatric endocrinologists are usually the primary physicians involved in the medical care of infants and children with intersex disorders. The specialty also deals with hypoglycemia and other forms of hyperglycemia in childhood, variations of puberty, as well other adrenal, thyroid, and pituitary problems. Many pediatric endocrinologists have interests and expertise in bone metabolism, lipid metabolism, adolescent gynecology, or inborn errors of metabolism.
