Q: Could white breast discharge from my nipples be a problem?

A: Common causes of galactorrhea include:

• Use of certain psychoactive drugs
• Prolactinoma (high prolactin)
• Hypothyroidism (low thyroid)
If you ovulate regularly, then the galactorrhea is unlikely to be a problem when trying to conceive. If you do not ovulate, then the galactorrhea could be a sign of elevated prolactin (hyperprolactinemia). Either way, you may want to talk to your doctor about this discharge and probably have your prolactin level checked.
