Galactorrhea refers to a condition in which the breast produces milk flow when a woman is not nursing. Women who have had multiple pregnancies may express small amounts of milk at times, and this is not abnormal. Milk production occurs because a hormone called Prolactin is released
by the pituitary gland. A variety of factors may play
a role in abnormal milk
production.
