The darkening of nipples after the birth of a baby is a normal physiological phenomenon and does not require special treatment. After the birth of a baby, pigmentation caused by hormonal disorders in the body can lead to darkening of the nipples and areolas and the phenomenon of black nipples, which can even be accompanied by skin discoloration, such as dark black skin changes on the face and abdomen. When breastfeeding is stopped, the hormones in the body can gradually return to normal, some of the pigmentation can be gradually absorbed, and the skin color can return to normal to some extent. However, if the patient feels that it affects the beauty of the skin, he or she can go to the dermatology or cosmetic surgery department of a regular hospital and decide whether to undergo conservative medication or surgery after a thorough evaluation by a specialist. In daily life, patients should avoid taking drugs that may cause hormonal disorders, eat a light diet, avoid staying up late, sleep early and wake up early.
