How long does it take for the lower body to return to normal after normal delivery depends on the actual situation, there are the following situations: firstly, there are many unexpected situations when women deliver by normal delivery, if there is no vaginal laceration, it will be able to return to normal after one month, the residual material inside the uterus will be almost eliminated after one month, basically it will not affect the body; secondly, if there is perineal and vaginal laceration during normal delivery, the recovery time will be longer, it will take about one month to two months. If the perineal laceration is closed with silk sutures, the sutures will need to be removed after delivery, and the sutures will need to be removed for a period of time to avoid further laceration. One month after the birth, the malodorous fluid is almost gone, but you can not rush to have intercourse, you need to observe the physical symptoms and wound situation, so as not to affect the recovery of the wound.
