Women often experience emotional changes after childbirth, which may be related to mental tension, stress, and physical fatigue postpartum. Clinically, this is mainly manifested as a decline in psychological function or impairment in social functions, presenting as negative emotional states with prolonged duration. Symptoms primarily include feeling low, frequent crying, insomnia, loss of appetite, depression, and intense guilt and feelings of inferiority towards the baby. These are all symptoms of postpartum depression.
