There is no need to express residual milk after weaning from breastfeeding, and generally the body can gradually absorb the residual milk on its own. Residual milk refers to the yellow, sticky substance that remains in the milk ducts after the patient stops breastfeeding. When the body no longer needs the breasts to produce milk, the milk will be absorbed by the breasts themselves, and there is no need to drain the residual milk. Because the milk can circulate in the mammary glands, as the weaning time goes by, the residual milk will be gradually absorbed by the body, so the milk does not need to be discharged, and after a long time, it will be fully absorbed, which is not harmful to the body. After weaning, patients need to reduce the squeeze on the breast, if there is any discomfort, it is recommended to consult a doctor in time to clarify the cause of the disease and then reasonable treatment.
