The production of milk does not end immediately after weaning, but rather decreases over a period of time before there is no milk production at all. In the vast majority of cases, milk secretion is gone after about three months of weaning. If there is still milk secretion, the following diseases should be ruled out: 1) dilated milk ducts, there will still be milk secretion. 2) hyperprolactinemia can also lead to milk secretion. It is recommended to go to the hospital to do sex hormone six tests, do color ultrasound examination of the breast, to understand the specific situation, according to the specific situation of the clinical need to give appropriate intervention. It is also recommended that during the initial weaning phase, it is best to eat a diet with less greasy food and less soup, both of which will reduce milk secretion.
