Growth Hormone Deficiency FAQs (cont.)
IN THIS ARTICLE
What causes growth hormone deficiency?
Growth hormone deficiency is caused by low or absent secretion of growth hormone from the pituitary gland. This condition may be present at birth, or it may develop after birth due to trauma, infections, radiation to the head, or other conditions (for example, tumors).
Adults with growth hormone deficiency usually have a history of pituitary tumors that may have been treated with surgery or radiation.
In some cases, no cause can be identified.
