How common are irregular periods in hyperprolactinaemia?

Hyperprolactinaemia means prolactin is higher than expected. The change may be linked with breast milk leakage when not breastfeeding, breast tenderness, reduced sexual desire, or difficulty conceiving, although some people have no obvious symptoms. Medicines, thyroid problems, pregnancy, and conditions affecting the pituitary gland can influence prolactin. One irregular cycle does not establish the cause.

Keep a record of period dates, flow, spotting, headaches, vision changes, and any nipple discharge. Tell your clinician about every medicine and supplement, including medicines for mood or nausea, because some can affect prolactin. A clinician may repeat a blood test under suitable conditions and investigate related hormones or the pituitary when the history calls for it. Do not stop prescribed medicine without advice.

Get urgent medical help for a sudden severe headache, new vision loss, fainting, or severe pelvic pain with bleeding. Arrange prompt assessment for persistent milk discharge when not breastfeeding, repeated missed periods, or headaches with visual symptoms. Heavy bleeding, weakness, or possible pregnancy with pain or bleeding also needs timely care.

Could any of my medicines affect prolactin? Should the prolactin test be repeated? Do my headaches or vision symptoms change the assessment? What other reasons for irregular periods should we consider?
