Pediatric Endocrinology is a branch of pediatrics that deals with hormonal problems in infants, children and adolescents. 

Endocrine glands, such as the pituitary gland, release hormones into the bloodstream. Hormones are chemicals that affect how other parts of the body work. For example, hormones decide how a child grows and matures.  

Problems seen by pediatric endocrinologists are often quite different from those commonly seen in adults. Special training in pediatric conditions as they relate to growth and development is important. Hormonal problems are often present for life. Pediatric endocrinologists deal with hormone disorders at all stages of childhood.
