The puerperium is the period of time from the delivery of the placenta to the recovery of all organs of the mother’s body, except the breast, to a non-pregnant state, usually about 6 weeks. During this period, the mother should rest in order to promote the recovery of her body functions. In order to adapt to the development of the fetus and prepare for childbirth, the whole body of the pregnant woman undergoes significant changes during pregnancy, while the delivery will cause damage to the uterus and birth canal of the woman, which will take some time to recover after the delivery. During the puerperium, women experience a series of manifestations, such as the lowering of the uterus into the pelvic cavity, uterine regeneration, discharge of malodorous fluid, and increased sweating and urination to reduce excess blood volume. At the same time, the tone and peristalsis of the gastrointestinal tract are restored, so that the digestive capacity returns to normal. In addition, women who do not breastfeed or partially breastfeed may have a return of menstruation, and at the same time may reflexively cause painful contractions when breastfeeding after delivery. Therefore, it is recommended that women go to the hospital for postpartum review after the puerperium to observe whether there is any abnormal vaginal discharge, whether the uterus is fully restored to its non-pregnant state, whether there is any abnormal pressure pain in the bilateral adnexa, whether there is any postpartum infection, and the recovery of the incision of those who had cesarean section. In addition, women are very fragile during the puerperium and should take good personal care. Women should take sufficient rest, avoid substantial activities, and supplement all kinds of nutrition in time so that their bodies can recover as soon as possible.
