The common causes of milk loss in breastfeeding women include malnutrition, inappropriate breastfeeding methods and mental factors, which can be solved by increasing nutrition, changing breastfeeding methods and regulating emotions. 1. Some women have insufficient nutrition during breastfeeding due to reduced food intake, which affects milk secretion and leads to decreased milk production. They should take more nutrition and eat more fish, meat and other foods that can promote milk secretion. 2. Some women do not breastfeed their babies in a proper way for various reasons, or they breastfeed their babies less often due to work, which will affect the secretion of milk and lead to a decrease in milk supply. You should learn the correct way of breastfeeding and increase the frequency of breastfeeding to increase the amount of milk. 3. During breastfeeding, individual women may suffer from nervousness, anxiety, depression, etc., which may affect the function of the hypothalamus-pituitary gland and disrupt the secretion of hormones, leading to a decrease in the secretion of breastmilk.
