The reason for the lack of milk production is that the baby is not allowed to suckle the breast in time after delivery, or the lactogen secretion is insufficient. The main reason for insufficient milk secretion is not letting the baby suckle on the breast in time after delivery. When the mother comes out of the maternity ward, she needs to let the baby suckle on the breast in time, so that it can promote milk secretion, encourage the mammary ducts to be smooth, and the milk will increase, etc. If the lactation secretion is insufficient, the mammary glands will produce less milk. If lactogen secretion is insufficient, the mammary glands secrete less milk. Low diet and poor mood after delivery may inhibit the secretion of prolactin, resulting in low milk. If the milk is insufficient and does not rise after delivery, there is a possibility of insufficient lactogen secretion. Low milk and no rise in the month, you need to go to the hospital in time to clarify the diagnosis and standardize the treatment, do not self-medication, to avoid bringing adverse consequences to the body.
