The amount of milk secretion can gradually decrease on its own, with individual differences in the duration. After weaning, milk will continue to be secreted and will easily lead to breast swelling and pain, which is called breast milk increase. If the amount of milk secretion is usually low, the duration of milk secretion after weaning will be relatively short, generally lasting about 7 days. If your milk secretion is strong, you will have more obvious symptoms of milk increase after weaning, which usually lasts for more than 10 days before you can withdraw your milk. In this case, we can take a gradual approach to weaning, such as gradually reducing the number of breastfeeding sessions for young children, in addition to using estrogen, fried malt and external application of mannitol under the guidance of a doctor. During the weaning period, women should pay attention to rest, keep a happy mood and minimize the intake of greasy food. If you find redness, swelling and pain in the breast worsening, it is recommended to visit the breast surgery department in time.
