After pregnancy, under the effect of estrogen, the vaginal wall will become abnormally soft, so when the uterus gradually increases in size, due to gravity, it presses on the vaginal fornix, which causes the vaginal wall to bulge out. In the majority of cases, this bulging condition improves naturally after delivery. However, if you have a vaginal delivery, the prenatal part of the vagina will often compress the pelvic floor muscles for a longer period of time, which will cause the pelvic floor muscle tone to decrease, so it is recommended to do pelvic floor rehabilitation therapy as soon as possible after the delivery. Through electrical stimulation, the local muscle tone can be restored, which will also improve the relaxation of the vaginal wall and make the bulging of the vaginal wall recover as soon as possible, and it is recommended to do three courses of treatment to achieve the purpose of healing. It is also recommended that after the pelvic floor rehabilitation treatment, you can also do anal lifting exercises, and adhere to more than half a year, in the clinic will also prevent the expansion of the vaginal wall, and to prevent the prolapse of the uterus.
