The most common cause of galactorrhea is nonpuerperal hyperprolactinemia,or excessive amounts of prolactin.A variety of exogenous agents (such as drugs)and disorders can trigger one of these three mechanisms,thereby causing hyperprolactinemia.Hypothyroidism causes increased secretion of hypothalamic thyroid-releasing hormone,which stimulates the release of prolactin from the pituitary.The proliferation of lactiferous breast ducts is not associated with galactorrhea.
