The problem is not a serious threat to health, although it may be annoying. However, the underlying cause of galactorrhea may be a pituitary tumor, which is more serious and may lead to other symptoms. Galactorrhea is uncommon in women and rare in men. It is usually caused by excessive amounts of the female sex hormone estrogen, which can occur during pregnancy or from taking oral contraceptives or some other medications. Another possible cause is excessive production of the hormone prolactin.
Prolactin is made by the pituitary gland and stimulates milk production.
Galactorrhea can also be caused by a disorder of the pituitary gland such as a tumor or may occur for no apparent reason. In women, galactorrhea is often coupled with an Absence of periods. In order to eliminate the possibility of a pituitary tumor or another underlying disorder the Endocrinologist will probably refer you for diagnostic tests, which may include a MRI scan and blood and urine tests. If tests fail to reveal any cause for the condition, you will probably not need any treatment. If the problem is caused by drugs, discontinuing the drugs will clear it up.
