Acromegaly is a disease
caused by excess
production of human growth hormone
by the pituitary gland
that begins in adulthood
. If the hormonal disorder
begins in childhood, the resulting condition is called gigantism
At adulthood, the bones are no longer able to grow longer, so they grow thicker instead, which is particularly noticeable in the case of small bones in the hands and feet, and in the skull, and the disease is characterized by deformities in these parts of the body.
Acromegaly is often initiated by cancer of the pituitary gland, and treatment consist of radiation therapy or removal of the gland, combined with hormone therapy. Like gigantism, acromegaly is often accompanied by other hormonal disorders that must also be treated.
