Step-by-step explanation:
Acromegaly is a hormonal disorder that develops when the pituitary gland produces too much growth hormone during adulthood. This condition is characterized by the enlargement of bones in the face, hands, and feet that are still capable of growth. It can cause physical changes like increased size of the hands, feet, and face. One example of gigantism caused by the overproduction of growth hormone in childhood is Martin Van Buren Bates, who grew to a height of 7 feet 9 inches.
