The time for menstruation to resume after cesarean delivery varies from person to person due to the woman’s own physical condition, ovarian recovery and whether she is breastfeeding or not. In general, normal ovulation and menstruation will resume about 4-6 weeks after cesarean delivery if the mother is not breastfeeding and her ovaries are recovering well. If the mother chooses to breastfeed, the time to resume menstruation varies, with most resuming around 18-20 weeks. The longer a woman breastfeeds, the later her menstruation may resume, and some breastfeeding mothers may not have a period during the entire breastfeeding period. When breastfeeding is over, menstruation will resume only after the estrogen and progesterone gradually return to their normal cyclic changes as the body’s lactogen level decreases. In addition, after a cesarean delivery, the mother needs to pay attention to nutritional intake, mainly a light diet with high protein, and at the same time keep her mood happy in order to promote physical recovery.
