Dwarfism [SEP] Causes
Dwarfism can result from many medical conditions, each with its own separate symptoms and causes. Extreme shortness in humans with proportional body parts usually has a hormonal cause, such as growth-hormone deficiency, once called "pituitary dwarfism". Two disorders, achondroplasia and growth hormone deficiency, are responsible for the majority of human dwarfism cases.
