Question

Acromegaly is due to hypersecretion of

  • insulin

  • thyroxine

  • growth hormone

  • None of these

Answer

C.

growth hormone

Growth hormone (GH) is secreted by anterior pituitary gland. It works with thyroid hormone and controls the normal growth. Hypersecretion (over production) of growth hormones in children causes the bones to grow unusually long. This results in a condition known as gigantism. But in adults, hypersecretion of growth hormone causes the bones of hands and face to thicken. This results in a condition called as acromegaly.
