Pediatric endocrinology
Endocrinology deals with disorders of the endocrine glands (the pituitary, thyroid, parathyroid and adrenal glands, ovaries, testicles, and part of the pancreas). Pediatric endocrinological diseases differ from adult diseases in many respects, as the disease processes affect a growing and developing organism. Disorders of the hormonal system also affect the metabolism (disorders of body weight, energy expenditure, etc.) and the functioning of many other organ systems (nervous system, cardiovascular system, immune system, etc.), hence there can be a wide range of consequences.
