Milky or watery discharge from both breasts two years after stopping breastfeeding is not residual milk and should be investigated. The commonest reason is a raised
prolactin level, which can come from a small benign pituitary lesion, an underactive
thyroid, or several medicines including some used for acidity, nausea, blood pressure and mood. Nipple stimulation, including frequent checking, keeps the discharge going. Watery or milky discharge from both sides is generally less concerning than discharge from a single duct or discharge that is blood stained.
Next Steps
Please see a gynaecologist or a breast specialist and ask for serum
prolactin and
thyroid function tests, and take a list of every medicine and supplement you use. A clinical breast examination should be part of the visit.
Health Tips
Stop squeezing or checking the breasts, as that alone sustains the discharge. Discharge from one breast only, blood in it, or a new lump needs prompt assessment.
