Occasionally a teen or adult woman may notice a milky-white discharge from one or both breasts. This condition is called “galactorrhea,” pronounced: gah-lack-toe-ree-ah. This may be a side effect of certain medicines (such as drugs for mood disorders or rarely birth control pills), a hormone imbalance (such as hypothyroidism or low thyroid hormone level) or a problem with the pituitary gland (causing high prolactin levels). Although it is not an emergency, you should make an appointment with your health care provider to get checked so you can find out the cause and get treated.
