The process of pregnancy and childbirth has both beneficial and negative effects on women’s health. The benefits are: 1) changes in the endocrine function of the body during pregnancy and childbirth, which may lead to the disappearance or relief of primary dysmenorrhea; 2) breastfeeding after childbirth, which can reduce women’s risk of breast cancer, breast enlargement and other diseases. The disadvantages are that during the process of pregnancy, it can easily lead to some specific diseases in pregnant women, such as osteoporosis, gestational diabetes, gestational hypertension, etc. The process of delivery may also lead to damage to the woman’s birth canal and increase the incidence of infectious diseases of the reproductive system.
