What is the name of the condition that affected Robert Wallow?

Robert Wadlow was affected by a condition known as gigantism, which is caused by an overproduction of growth hormone, often due to a benign tumor on the pituitary gland. This condition led to his extraordinary height of 8 feet 11 inches, making him the tallest person in recorded history. Wadlow's height resulted in various health complications and ultimately contributed to his early death at the age of 22.
