Galactorrhea is Breast milk production when not pregnant or breastfeeding. This is usually due to an elevation of the hormone prolactin. This can be caused by various factors, including medications, hormonal imbalances, certain medical conditions, and sometimes even just increased breast stimulation.
This type of nipple discharge can come from only one nipple, but it typically comes from both. It can flow spontaneously or just be noticed if you pinch the area around your nipple.1
It is usually a light white colour resembling milk, but may also be yellowish or greenish.
While galactorrhea typically involves a milky discharge, other types of nipple discharge can also occur, such as bloody discharge, which may require further investigation.
Possible Causes of Galactorrhea:
-
Hormonal Imbalances:
Elevated prolactin levels, often linked to a pituitary tumour or other hormonal disorders, can trigger milk production.
Hormones can cause normal breast discharge that’s related or unrelated to pregnancy. Common hormonal causes of nipple discharge include:
Normal hormonal shifts (e.g., menstruation, pregnancy, breastfeeding, pregnancy loss)
Hormonal medication side effects (e.g., birth control pills)
Hormone-related health conditions (e.g., pituitary gland problems)

Medications:
Certain medications, like some birth control pills, antidepressants, and blood pressure medications, can also lead to increased prolactin levels.
- Other Medical Conditions:
- Underactive thyroid (hypothyroidism), kidney disease, and certain types of tumours can also cause galactorrhea.
- Breast Stimulation:
Overstimulation of the breasts, either from touching or due to other medical interventions, can also induce milk production.

Stress:
Stress can sometimes lead to the release of prolactin, causing breast milk production.
-
Injury or Trauma:
Injury or trauma to the spinal cord or chest can also trigger galactorrhea.
In some cases, galactorrhea may resolve on its own without treatment, especially if the underlying cause is medication-related.
While galactorrhea typically involves a milky discharge, other types of nipple discharge can also occur, such as bloody discharge, which may require further investigation.
For medical advice or diagnosis, consult a professional.
