The short explanation
Missed periods together with milky nipple discharge when you are not pregnant or breastfeeding is a pattern doctors recognise. A common reason is a raised level of prolactin, the hormone that normally stimulates milk after childbirth. High prolactin can switch off ovulation, so periods stop. Prolactin can rise for several reasons, including some medicines, an underactive thyroid, stress, and a small non-cancerous growth in the pituitary gland called a prolactinoma. These are treatable. A blood test is usually the first step, and further tests depend on the result.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Tell the doctor about any medicines you take, including those for mood, acidity or nausea, because some can raise prolactin.
- Headaches or changes in your vision are worth mentioning, as they help the doctor decide whether a scan of the pituitary is needed.
- Pregnancy is usually ruled out first with a test, even if you think it is unlikely.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell why your periods have stopped or what is causing the discharge. Blood tests and an examination are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Should my prolactin and thyroid levels be checked?
- Could any of my medicines be causing this?
- Do I need a scan of my pituitary gland?
- How will this affect my chances of pregnancy in future?
