Hyperprolactinaemia is a persistently elevated blood prolactin level found outside pregnancy or breastfeeding. In women it commonly causes irregular or absent periods and anovulation, sometimes with breast discharge. In men it can reduce testosterone and sperm counts and lower libido. Evaluation looks for causes including hypothyroidism, a pituitary adenoma (assessed with pituitary imaging if levels are significantly raised), and certain medicines. Treatment addresses the underlying cause and is managed by a specialist; this is not something to self-treat.
Also known as: high prolactin, elevated prolactin, raised prolactin
