A woman who has given birth by caesarean section will be in labor for about 42 to 56 days. The term “menstruation” refers to the medical term “puerperium”, which is the period of time between the delivery of the placenta and the return of the body to its non-pregnant state (except for the breasts), which is usually about 6 weeks. The uterus returns to its normal size about 6 weeks after delivery, the blood system recovers in about 3 to 4 weeks, the digestive system recovers in 1 to 2 weeks, the urinary system recovers in about 2 to 8 weeks, and the abdominal muscle tone recovers in about 6 to 8 weeks. During the puerperium, the body and mind undergo drastic changes. Most women recover well during the puerperium, while a few may develop puerperium diseases, such as puerperium infections, late postpartum hemorrhage, and postpartum depression. During puerperium, it is important to pay attention to reasonable diet, appropriate exercise, regular postnatal visits and health checkups to prevent puerperal diseases. Most of the puerperal period is characterized by physiological changes, so if there are any abnormalities, it is necessary to consult a doctor in time and give appropriate treatment under the doctor’s guidance.
