Q. What causes nipple discharge in women who are not pregnant or breastfeeding?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Nipple discharge in women who are not pregnant or breastfeeding can be caused by a variety of factors, and it is often considered abnormal. Here are some of the common causes of nipple discharge in non-pregnant, non-breastfeeding women:
1. Hormonal fluctuations: Hormonal imbalances, such as elevated levels of the hormone prolactin, can lead to nipple discharge. Prolactin is responsible for milk production, and high levels of this hormone in non-pregnant or non-breastfeeding women can result in nipple discharge.
2. Medications: Some medications, including certain antidepressants, antipsychotics, and high blood pressure medications, can cause nipple discharge as a side effect.
3. Infections: Infections of the breast, such as mastitis (an infection of the breast tissue) or a breast abscess, can lead to nipple discharge. These infections are usually associated with other symptoms like breast pain, redness, and swelling.
4. Benign breast conditions: Certain benign (non-cancerous) breast conditions, such as intraductal papillomas or fibrocystic breast changes, can cause nipple discharge. These conditions may lead to the formation of small growths or cysts within the breast ducts.
5. Ductal ectasia: Ductal ectasia is a condition in which the milk ducts beneath the nipple become widened and filled with fluid. This can cause nipple discharge, often with a green or brown color.
6. Trauma or injury: Physical trauma or injury to the breast can sometimes result in nipple discharge.
7. Hormone replacement therapy (HRT): Women taking hormone replacement therapy, particularly with estrogen and progesterone, may experience nipple discharge as a side effect.
8. Breast cancer: Although less common, nipple discharge can be associated with breast cancer. If the discharge is bloody, persistent, and occurs spontaneously, it should be evaluated by a healthcare provider to rule out malignancy.
It's essential for women who experience nipple discharge outside of pregnancy and breastfeeding to consult a healthcare professional for a proper evaluation and diagnosis. The underlying cause of the discharge can vary, and appropriate treatment or further testing may be necessary to determine the exact reason and address any underlying medical conditions.
