Milky breast discharge, also known as galactorrhea, can be a surprising and sometimes worrying symptom—especially if you're not breastfeeding or pregnant. But while it's often harmless, it's essential to understand what might be going on in your body.
What Is Milky Breast Discharge?
Milky discharge refers to a whitish fluid that leaks from one or both nipples. It may occur spontaneously or only when the breasts are squeezed. Though it's common among women, it can also occur in men and children, and it’s usually linked to hormonal imbalances or certain medications.
Common Causes of Milky Discharge
- Hormonal Imbalance – High Prolactin Levels
The most common cause is an elevated level of prolactin, the hormone responsible for milk production. High prolactin can result from:- A non-cancerous pituitary tumor (prolactinoma)
- Thyroid problems (especially hypothyroidism)
- Stress or poor sleep habits
- Certain medications (especially antidepressants, antipsychotics, and blood pressure drugs)
- Nipple or Breast Stimulation
Frequent breast stimulation—either from tight clothing, sexual activity, or habitual touching—can cause your body to release prolactin. - Pregnancy or Recent Childbirth
Even if you are not currently breastfeeding, a recent pregnancy can result in lingering breast milk discharge. - Medications and Herbal Products
Some medications and even herbs like fenugreek, fennel, and anise may increase prolactin and cause discharge. - Pituitary or Brain Conditions
Tumors or lesions in the pituitary gland (located at the base of the brain) may disturb the hormonal control center and increase prolactin secretion. - Chronic Medical Conditions
Conditions such as kidney disease or liver disease may also interfere with hormone breakdown, causing elevated prolactin levels.
When Should You Be Concerned?
You should seek medical attention if:
- You’re not pregnant or breastfeeding and the discharge is persistent.
- It’s coming from only one breast or is spontaneous (comes out without squeezing).
- The discharge is bloody, clear (not milky), or foul-smelling.
- You experience changes in your menstrual cycle or vision.
- You feel a lump in the breast or underarm area.
