During the growth period, release of too much growth hormone can lead to
Gigantism
An excess of growth hormone during the growing period causes gigantism. An excess of growth hormones affects adults and children differently. Excess secretion of growth hormones in children causes gigantism. This excess in growth hormone leads to excessive linear growth, causing the individual to be very tall, with abnormally large hands and feet and coarse facial features including a prominent forehead and jaw. Excess growth hormone in adults causes acromegaly.
