For babies, breast milk is the most nutritious food in the world and the most suitable food for their growth and development, but some new mothers have less milk after giving birth and cannot feed their babies. So what are the causes of low milk for lactating mothers? 1, there is no early opening of milk, the mother can feed the baby half an hour after delivery to stimulate milk secretion, but also to make the secreted milk timely discharge, which can stimulate the pituitary gland to regulate the repeated secretion of milk. If the baby is not allowed to suckle in time when the milk is distended after delivery, the secretion of milk will be reduced because the pituitary gland’s regulatory function is inhibited and milk secretion will be reduced. If mastitis is caused by milk stagnation, it will also stimulate the pituitary gland resulting in reduced milk secretion. 2. Feeding stimulation decreases. Many white-collar mothers leave early and return late due to their work, so the infant’s sucking is not enough, which reduces the breastfeeding stimulation and the milk secretion will decrease accordingly. 3.The capillary fibers in the bra enter the breast tissue, resulting in blockage of the breast ducts and reducing the secretion of milk. As the nipple is pressed by the bra, the friction between the nipple and the bra increases, the fibers on the bra will gradually enter the breast ducts, thus blocking the breast ducts and causing some new mothers to have less milk or no milk. 4.Emotional influence: depression, tension, irritability and other bad emotions will affect the function of the pituitary gland of lactating mothers and inhibit the secretion of prolactin, thus causing a decrease in milk secretion. 5, unreasonable diet structure: due to the modern women’s pursuit of a slim body, many new mothers are afraid of gaining weight after giving birth, reducing the intake of protein and fat, these nutrients will also reduce the secretion of milk if the intake is insufficient. 6, postpartum abuse of contraceptives, the fear of pregnancy again and abuse of contraceptives, affecting the pituitary gland to promote lactation function and lead to a reduction in lactation mastitis, will also stimulate the pituitary gland resulting in reduced lactation.
