Two Diseases Resulting from Hyperfunction of the Pituitary Gland Are

Question

Two diseases resulting from hyperfunction of the pituitary gland are:
A) Simple goiter and Hashimoto thyroiditis.
B) Graves disease and Cushing syndrome.
C) Cretinism and myxedema.
D) Gigantism and acromegaly.

Accepted Answer

Gigantism and acromegaly are both caused by an excess of growth hormone produced by the pituitary gland. Gigantism occurs if the excess growth hormone is produced before the epiphyseal plates of the long bones close, leading to excessive growth in height. Acromegaly occurs if the excess growth hormone is produced after the epiphyseal plates close, leading to a thickening of the bones in the face, hands, and feet.
