After pregnancy, the areola will increase in size, mainly because after pregnancy, the breasts will increase in size under the effect of estrogen, so the areola will also increase in size accordingly. The most obvious phenomenon is the coloring of the nipples and areolas, which is caused by the action of estrogen and is a normal phenomenon after pregnancy. It is recommended to take good care of your breasts during pregnancy and to wash them with warm water every day. If there is nipple invagination, it is recommended to gently pull the nipple after applying hot compresses, which will help the newborn to breastfeed more smoothly after birth. In addition, if there is a clinical irregularity in the areola, it is important to go to the hospital for examination to rule out the possibility of lesions.
