Prolactin is a hormone secreted by the pituitary gland that is principally responsible for stimulating the lactation process after childbirth. Quantities of prolactin also increase in women during pregnancy and in the weeks that follow in cases of breastfeeding. Nevertheless, an excessive blood level of prolactin outside of these specific contexts is called hyperprolactinaemia, which can be caused by a number of different factors, such as certain medication or a pituitary adenoma or tumor. Hyperprolactinaemia is suspected when two symptoms are observed together: absence or disrupted periods, and secretion from the nipples.
