Acromegaly is a condition in which the body produces too much growth hormone, resulting in excessive growth of certain parts of the body, such as the face, feet, hands, heart, and bones. It is a condition affecting middle-aged adults.

The most common cause of acromegaly is a benign tumors of the pituitary gland, but tumors in other areas, such as the pancreas, liver or brain may also result in high levels of the growth hormone.
