Gigantism is typically caused by an overproduction of growth hormone, a hormone produced by the pituitary gland. Too much growth hormone can cause the body to grow far larger than average. This can lead to excessive bone and tissue growth, resulting in an individual who is taller and heavier than most.
Dwarfism is typically caused by an underproduction of growth hormone. Too little growth hormone can cause the body to grow far smaller than average. This can lead to inadequate bone and tissue growth, resulting in an individual who is shorter and lighter than most.
