Acromegaly
Acromegaly is a medical condition that happens when the anterior (rear) pituitary gland makes too much growth hormone (GH), after a person has passed puberty. If this happens before puberty it causes a condition known as gigantism. A number of medical conditions may cause the pituitary gland to make too much growth hormone, but the most common cause is a tumor on the pituitary gland called a pituitary adenoma'
