What causes acromegaly?

ANSWER

The most common cause is a pituitary adenoma, a noncancerous tumor that makes growth hormone from your pituitary gland. The pituitary gland is in the skull, just below the brain. It is part of your endocrine, or hormone system. Because of the tumor, your body makes too much growth hormone.

Once in a while, tumors in the pancreas, liver, or parts of the brain can cause high levels of growth hormone. That leads to higher levels of another hormone, called insulin-like growth hormone, which causes the symptoms you see.
