The white discharge from the nipples during late pregnancy needs to be observed to see if there is any pain or itching. If there is no discomfort, this is a normal manifestation, because during pregnancy the placenta secretes a lot of estrogen that causes the ducts of the breast to expand and there is milk secretion, this is a physiological manifestation during pregnancy and does not require special treatment. During this period, try to keep the area dry and clean, and pay attention to flushing with water. If there is a painful or itchy sensation and white discharge, it is considered to be caused by bacterial infection and should be disinfected with iodophor and then observed. If the pain is more serious, it means that there is an internal inflammatory infection, which needs to be treated with oral anti-inflammatory drugs, such as cephalosporin or amoxicillin. You should pay attention to a light diet, do not eat spicy and stimulating food, wear loose cotton underwear to reduce the local skin stimulation.
