Young boy aged 11 years old undergoing treatment with a growth hormone, is seen here being measured by his doctor. Growth hormone is synthesized and stored in the anterior pituitary gland. Under normal conditions it promotes growth of the long bones in the limbs and increases protein synthesis. Childhood deficiency of growth hormone results in dwarfism, whereas excess production causes gigantism. Where a deficiency is spotted in childhood injections of growth hormone can be administered.
