Growth hormone fuels childhood growth and helps maintain tissues and organs throughout life. It's produced by the pea-sized pituitary gland located at the base of the brain. Beginning in middle age, however, the pituitary gland slowly reduces the amount of growth hormone it produces. This results in an increase in the linear growth of bones, especially the long bones in the arms and legs. Patients with gigantism usually dies a premature death due to infection, progressive debility or hypopituitarism. Bookshelf The result is an increase in volume and a decrease in the osmolarity of the blood.
