In adults, excessive growth hormone can lead to which condition?

Excessive growth hormone in adults leads to acromegaly, which is characterized by the abnormal growth of bones and tissues. This condition arises when there is a tumor on the pituitary gland that secretes excess growth hormone. As a result, individuals may experience enlarged hands and feet, facial changes such as protruding jaw or brow, and thickened skin.

Acromegaly differs significantly from dwarfism, which is a condition seen in childhood due to insufficient growth hormone, not an excess. Hypertension can be a consequence or associated condition in individuals with acromegaly, as the increased body mass can lead to higher blood pressure, but it is not a direct result of excess growth hormone alone. Cushing's syndrome, on the other hand, arises from excessive cortisol levels, which is unrelated to growth hormone regulation. Thus, acromegaly is the primary condition associated with excessive growth hormone in adults.
