Dwarfism is a condition of short stature. It is defined by Little People of America (LPA) as an adult height of 4 feet 10 inches or under, because of a medical or genetic condition. Although other groups may say certain forms of dwarfism varies to 5 feet, the average height of an adult with dwarfism is 4 feet. The hormones/glands that's affected by dwarfism would be the pituitary gland because it messes up the amount of growth hormone that needs to be produced. Signs of dwarfism would be short limbs, fat stubby hands, and a big head. Dwarfism is genetic or hereditary. Dwarfism is treated sometimes by surgery, metal plates are injected into the bone to help it grow properly.
