Postpartum vaginal laxity is caused by overstretching or damage to the pelvic floor tissues during delivery. Generally, it can be partially recovered about three months after delivery, but it is difficult to fully recover to the pre-pregnancy state. Recovery methods: First, pelvic floor muscle rehabilitation training, twice a day, fifteen minutes each time, to carry out the exercise of anal lifting. Take the action of holding your bowels, lift your breath upward, and during the process of urination, take the initiative to terminate urination and continue urinating after a short while. You can also have planned rehabilitation exercises, or yoga training. Secondly, many obstetrics and gynecology hospitals and maternal and child health centers have started postpartum pelvic floor rehabilitation programs, which can be assessed and followed by electrophysiological treatment to help recovery. Thirdly, in more severe cases of postpartum vaginal laxity, tension incontinence, anterior vaginal wall bulge and uterine prolapse are often combined and require surgical treatment.
