Hyperprolactinemia corresponds to a condition determined by the excessive production of the hormone prolactin by the pituitary gland (a small neuroendocrine gland found in the center of the brain that mediates communication between the hypothalamus and the rest of the body), resulting in blood values above those considered normal to ensure the proper performance of the processes regulated by the hormone itself, i.e., 25-30 ng/ml.
It is a fairly common endocrine disorder among women, who may suffer from it at various times in their lives, experiencing disturbances in ovulation and milk secretion resulting in the possible onset of amenorrhea and/or galactorrhea (milk leaking from the nipple even in women who have not recently given birth and are not breastfeeding).
More rarely, it can also affect men.
