In most cases of growth hormone deficiency, no single cause can be identified. However,
growth hormone deficiency causes can be different in both children and adults.
The pituitary gland makes growth hormone, which stimulates the growth of bone and other tissues.
Children who have too little of it may be very short. Treatment with growth hormone can stimulate growth.
People can also have too much growth hormone. Usually the cause is a pituitary gland tumor,
Too much growth hormone can cause gigantism in children, where their bones and their body grow too much.
In adults, it can cause acromegaly, which makes the hands, feet and face larger than normal.
Possible treatments include surgery to remove the tumor, medicines, and radiation therapy.
