Galactorrhea in women is lactation (the production of milk) when the woman is neither pregnant nor breast-feeding a child. Causes of galactorrhea in women include:
• Side effects of certain medications (such as some oral contraceptives, some anti-hypertensive drugs, some opiod drugs, and some drugs to treat mental conditions)
• Abnormally low secretion of the hormone, thyroxin, by the thyroid gland
• Secretion of hormones by tumors of the pituitary gland
• Diseases of the hypothalamus gland
• Other conditions
If you are experiencing galactorrhea, consult your physician for diagnosis and appropriate therapy. Treatment of galactorrhea depends on the underlying cause of the condition. See our Q&A called Treatment of Galactorrhea in Women.
