In general, the best time to repair the pelvic floor muscles after childbirth is usually between 42 days and 3 months after delivery. The pelvic floor muscles are usually stressed and damaged during normal delivery, resulting in postpartum pelvic floor muscle laxity, which can lead to stress urinary incontinence, pelvic organ prolapse or vaginal swelling and discomfort. Such women can go to the pelvic floor clinic for pelvic floor muscle function testing 42 days after delivery and undergo pelvic floor muscle repair treatment according to the test results. It is not recommended to do pelvic floor muscle repair treatment because there is still malignant dew during the 42 days postpartum period, which is the natural recovery period of a woman. After 42 days of postpartum, the dew has been cleared and the natural repair of the mother is basically completed, so it is the best time to do pelvic floor repair. During the pelvic floor repair period, it is necessary to pay attention to rest and avoid strenuous exercise and heavy physical labor to prevent the pelvic floor muscle repair from being ineffective.
