Patient's question:
I have had nipple discharge for 4.5 years. Two years ago, I went to the hospital for consultation, but the doctor didn't say much and just asked me to get a prolactin test. The prolactin levels were normal, so the doctor prescribed medication for breast hyperplasia, but it didn't help much. I haven't been back to the hospital since then. Now I have a baby. The baby is three and a half months old, and I have been breastfeeding exclusively. I would like to ask the experts, does non-lactating nipple discharge affect the breastfeeding child?History of onset and duration: 4.5 years
Medical history: 3 induced abortions, and nipple discharge started after the second induced abortion.
Previous diagnosis, treatment, and outcomes: Prolactin test was conducted, and the levels were normal.
Doctor's answer:
Nipple discharge is divided into two types: physiological and pathological. Generally, bilateral discharge may be physiological, such as when most women still have a small amount of milk secretion within one year of stopping breastfeeding; during the late stages of pregnancy, some pregnant women may express a small amount of pale colostrum from both breasts; in a few women, post-intense sexual climax may lead to temporary nipple discharge due to highly congested breast blood vessels, breast enlargement, and nipple erection; and during menopause, endocrine disorders may cause some women to secrete a small amount of milk. Additionally, conditions such as breast hyperplasia, duct ectasia, breast trauma, inflammation, various benign and malignant breast tumors, hyperprolactinemia, hypothyroidism, and pituitary tumors can all lead to pathological nipple discharge. The cause of nipple discharge is excessive prolactin secretion in the body. The causes of hyperprolactinemia are complex and include both physiological and pathological factors, which can be either systemic or local. For example, multiple induced abortions after childbirth can elevate prolactin levels; poor sleep, long-term use of sedatives or sleeping pills; long-term treatment for tuberculosis or intestinal tuberculosis with antitubercular drugs; post-marital women who need long-term oral contraceptives due to discomfort with an intrauterine device; as well as hyperpituitarism, pituitary microadenomas, hypothalamic disorders, and antihypertensive medications.Physiological discharge is often due to intense sexual stimulation, which temporarily increases prolactin levels but quickly returns to normal. In non-pregnant women, if lactation occurs alongside amenorrhea, it is referred to as galactorrhea-amenorrhea syndrome, which can lead to infertility. Duct ectasia may also cause a small amount of milky-like discharge, and some women with breast hyperplasia may experience nipple discharge accompanied by breast tenderness, likely due to endocrine disorders. If the discharge contains blood or is entirely bloody, it warrants caution regarding the possibility of breast cancer.
In summary, women with nipple discharge should not take it lightly but should also avoid panic. They should seek timely medical evaluation, such as smear tests of the discharge, fasting blood tests for prolactin, or even mammography, to determine the underlying cause and receive appropriate treatment.
