How common are stopped periods in Hyperprolactinaemia?

Hyperprolactinaemia means prolactin is higher than expected outside pregnancy or breastfeeding. The change may lead to missed or stopped periods, difficulty becoming pregnant, breast milk discharge, lower sexual desire, or vaginal dryness. Some people have no obvious symptom other than a change in their cycle.

Book a medical review when periods stop or become markedly irregular. A clinician may repeat a prolactin test, review medicines and pregnancy status, and check thyroid function or other hormones. If the result remains raised, the next assessment depends on the level, symptoms, and possible causes rather than on the missed periods alone.

Get prompt medical advice for new vision changes, persistent headaches, fainting, or severe weakness alongside stopped periods. Seek urgent help for sudden severe headache or sudden loss of vision. These symptoms can require rapid assessment of the hormone-producing area near the brain.

Ask whether any medicine, thyroid problem, pregnancy, or pituitary condition could explain the result. Clarify whether prolactin should be rechecked, whether testing needs special preparation, and which symptoms should lead you to contact the clinic sooner.
