How common is nipple discharge in hyperprolactinaemia?

Nipple Discharge is a common presentation of Hyperprolactinaemia, which means prolactin levels are higher than expected. The fluid is often milky and may occur outside pregnancy or breastfeeding.

Prolactin is a hormone involved in milk production. When its level rises, nipple discharge may occur along with irregular or absent periods, reduced fertility, lower sexual desire, vaginal dryness, or headaches. Some people have discharge without other symptoms.

Possible contributors include medicines, thyroid problems, pregnancy, breastfeeding, and conditions affecting the pituitary gland. A single result may need context because stress, recent nipple stimulation, and the timing of a blood test can influence interpretation.

Arrange a medical review for unexplained milky discharge, especially if you are not pregnant or breastfeeding. Tell the clinician about medicines, supplements, menstrual changes, headaches, and vision symptoms. Testing may include a repeat prolactin measurement, a pregnancy test, thyroid testing, and other checks guided by your history.

Seek prompt care for nipple discharge with a new breast lump, blood-stained fluid, or a change affecting one breast. Contact a clinician promptly for a new severe headache or visual disturbance, because these symptoms need assessment alongside a possible hormone problem.

Ask whether your medicines or thyroid function could affect prolactin, whether the test should be repeated, and what symptoms would require specialist review. If periods have changed, ask how hormone levels may relate to fertility and bone health.
