Low breast milk may be caused by malnutrition, lack of prolactin, blocked milk ducts, etc. Dietary adjustment, breast massage, nipple stimulation and other methods can be taken to increase breast milk. 1. Malnutrition: If the maternal intake of nutrients is insufficient, it may cause the phenomenon of low breast milk. It is recommended that mothers should pay attention to adjusting the diet structure in their daily life, and they should eat protein-rich foods, such as chicken, fish, and soybean products, which can have the effect of increasing breast milk. In addition, drinking appropriate soup food can also increase breast milk. 2. Mammary duct blockage: mothers can use warm towels to apply hot compresses to the breasts in daily life, or massage the breasts appropriately, which can help keep the ducts open and promote breast milk increase. 3. Lack of prolactin: If there is a lack of hormone in the mother’s body, it will also lead to insufficient milk, in which case the nipples should be stimulated to increase the secretion of prolactin in the pituitary gland through the nerve reflex, so that more milk can be produced. If the mother has the phenomenon of low breast milk, through the adjustment of diet structure, breast milk still does not increase, it is recommended to consult a doctor in time, under the guidance of the doctor to improve the relevant examination, to clarify the cause of the disease, and symptomatic treatment.
