If you have been weaned for two years and still have milk is an abnormal phenomenon, it is recommended that you take a blood test for sex hormone six, preferably on the second or third day of menstruation to understand the endocrine situation, and mainly to understand whether the prolactin is abnormally elevated. If prolactin is abnormally elevated, it is also necessary to rule out the possibility of pituitary tumors, because pituitary microadenomas can lead to elevated prolactin, so there is a possibility that the milk is still not completely clean. If there is no pituitary tumor in the examination, and it is purely caused by elevated prolactin, you can take bromocriptine for treatment. In addition, this situation should also exclude the possibility of dilated milk ducts, need to do color ultrasound examination.
