The vaginal laxity can be caused by the increased pressure of the uterus on the pelvic floor during pregnancy. 2. The vagina is overextended and less elastic because the fetus comes out of the vagina during normal delivery and the pelvic floor muscles and ligaments are damaged. However, it usually does not affect sex life, and after delivery, women can do pelvic floor rehabilitation therapy, such as electrical stimulation biofeedback therapy, to make the vagina return to its previous state as much as possible after exercise. Women themselves can also do anal lift exercises and postpartum gymnastics to tighten the buttocks muscles and increase the vaginal elasticity, or if the result is not good, they can take gynecological plastic surgery. After delivery, women should pay attention to rest, get enough sleep, don’t stand for a long time, keep warm, avoid wind and cold, keep happy, pay attention to nutrition and drink more water.
