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 test for prolactin. The prolactin test results were normal, and then the doctor prescribed medication for breast hyperplasia, but it didn't help much. I haven't been back to the hospital since. 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: Had 3 induced abortions. Nipple discharge started after the second induced abortion.
Previous diagnosis and treatment history and effectiveness: Tested for prolactin, results 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 experience a small amount of milk secretion within one year of stopping breastfeeding; during the late stages of pregnancy, some pregnant women's breasts may secrete a small amount of thin colostrum; in a few women, post-intense sexual climax, due to highly congested breast blood vessels, breast enlargement, and nipple erection, temporary nipple discharge may occur; and during menopause, endocrine disorders can cause some women to secrete a small amount of milk. Additionally, conditions such as breast hyperplasia, mammary duct ectasia, breast trauma, inflammation, various benign and malignant breast tumors, hyperprolactinemia, hypothyroidism, and pituitary tumors, all of which cause endocrine disorders, can lead to pathological nipple discharge. The reason for 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 systemic or localized. For example, multiple induced abortions after childbirth can lead to elevated prolactin levels; poor sleep, long-term use of sedatives or sleeping pills; long-term treatment for tuberculosis or intestinal tuberculosis with antitubercular drugs; married 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, leading to a temporary increase in prolactin, which quickly returns to normal. In women who have not been pregnant, if lactation occurs accompanied by amenorrhea, it is called hyperprolactinemic amenorrhea, which can lead to infertility. Mammary duct ectasia may also cause a small amount of milky-like discharge. Some women with breast hyperplasia may experience nipple discharge accompanied by breast tenderness, likely due to endocrine disorders. If the discharge is bloody or entirely bloody, it should raise suspicion of breast cancer. In summary, women with nipple discharge should not take it lightly but should also avoid panic. They should seek timely medical examination, such as smear tests of the discharge, fasting blood tests for prolactin, or even mammography, to identify the underlying cause and receive appropriate treatment.
