White granules on the areola of pregnant women are small nodules called Montgomery’s nodules. If you are not pregnant, Montserrat’s nodules also exist, but due to the development of the milk ducts after pregnancy, Montserrat’s nodules increase in size with the development of the breast, which is a normal physiological phenomenon and is not something to worry about. If there is nipple discharge, you can wash it with boiling water every night during pregnancy, this is colostrum, a special phenomenon after pregnancy, no need to worry and no need for treatment. You can’t stimulate your nipples for a long time after pregnancy, if you stimulate them, it may cause contractions.
