Breast pumps enable a woman to express her breast milk and do not normally lead to weaning. Breast pumps stimulate a woman’s breasts, and when the milk cannot be fed to the baby, it is necessary to use a breast pump to make the milk drain, at this time there is no milk stagnation, which is good for the body and does not lead to the occurrence of weaning. When weaning occurs in women, it is usually caused by a decrease in prolactin after stopping breastfeeding and not being able to express milk. When a breast pump sucks the milk out, the milk can continue to be produced without affecting the level of prolactin, so weaning does not occur. When women use breast pumps, they should master the correct way to use them, and if there are any uncomfortable symptoms, they need to go to the hospital in time, and under the guidance of the doctor to carry out appropriate interventions to protect the health of the breasts.
