Hyperpituitarism
Hypersecretion of Growth Hormone (GH) or Somatotropin Hormone (STH) from adenohypophysis of pituitary gland causes gigantism in children and acromegaly in adulthood. Gigantism involves excessive growth (lengthening) of bones with enlargement of internal organs as well. Acromegaly causes abnormal thickening of bones (due to ossification of periosteum) especially at face and margins of hand and feet.

Growth Hormone becomes inactive in adults
Epiphyseal plates close after adolescence
Bones loose their sensitivity to Growth Hormone in adults
