Hyperprolactinemia - Definition

Ask a question


Hyperprolactinemia defines an excessive production of prolactin in the blood, which is a hormone synthesized in the anterior lobe of the pituitary gland involved in stopping the menstruation and activating breast milk production in women who have given birth. When hyperprolactinemia is caused by an impaired function that requires consultation with an endocrinologist, it is advised to investigate a pituitary adenoma that could be the cause of increased prolactin levels in cases that do not involve a pregnancy. This could also be responsible for amenorrhea (absence of menstruation) and often bilateral galatorrhea (secretion of milk from both breasts). Addison's disease, stress, myxoedema, and the abuse of narcotics, can all also be the cause of hyperprolactinemia.
