What causes Growth Hormone Deficiency?
Growth hormones are produced by the pituitary gland, which is attached to the hypothalamus (a part of the brain that affects the pituitary gland) located at the base of the brain. Sometimes referred to as the master gland of the endocrine system, the pituitary gland controls the functions of the other endocrine glands through the secretion of certain hormones, and also produces human growth hormone. When the pituitary gland or the hypothalamus are malformed or damaged, growth hormone deficiency may result. Damage to the pituitary gland or hypothalamus may occur as a result of abnormal formation of these organs before a child is born (congenital, or present at birth), or as a result of damage that occurred during or after birth (acquired). Researchers have found that growth hormone deficiency may also be part of a genetic syndrome. However, in some cases, the cause of growth hormone deficiency is unknown (idiopathic).
