Prenatal depression, if it occurs in early pregnancy, may lead to fetal malformations. When prenatal depression occurs, some pregnant women may lose their appetite and their absorption and utilization of nutrients may be reduced, which may affect the absorption and utilization of nutrients by the fetus, thus affecting the normal development of the fetus. In addition, prenatal depression can induce disorders of the cortical nervous system, which in turn can induce disorders of the circulatory system, which can induce intrauterine distress of the fetus and placental disease, and in serious cases, affect the life and health of the pregnant woman and the fetus. Therefore, prenatal depression should be fully recognized as an unhealthy psychological factor, and family members, friends, and health care professionals should give full care to such people. Moreover, patients with prenatal depression are more irritable, often in a state of tension, and do not sleep and eat well. Psychological disorders can also appear after the birth of the fetus, and prenatal depression can induce postnatal depression, which is a burden for the family and for the raising of the newborn.
