Postpartum wall bulge can be recovered. The fetus is born through the mother’s vagina during natural birth, and the vaginal walls of the mother become bulged during normal labor and compression, which can be recovered through conservative methods and surgery after delivery. The best time to recover the pelvic floor muscles and the vaginal wall is within six months after delivery. For conservative treatment, anal lift training can be performed at home and will show significant improvement after one month. Women whose results do not improve significantly can go to the hospital for a review and recover with pelvic floor rehabilitation equipment. If the symptoms are serious and affect the quality of life, they can be repaired by surgery. During pregnancy, in order to avoid serious postpartum dilatation of the anterior and posterior walls, it is important to pay attention to a scientific diet and a reasonable mix, otherwise it can lead to serious vaginal damage during delivery and even uterine prolapse.
