Vaginal laxity is clinically caused by the following reasons: first, because during vaginal delivery, the pre-dewlap presses on the pelvic floor for a long time, which decreases the muscle tone of the pelvic floor, so vaginal laxity can occur. It is clinically recommended to do anal lifting exercises after vaginal delivery to prevent vaginal laxity, to prevent anterior and posterior vaginal wall bulge, and to prevent uterine prolapse. Secondly, because the function of organs decreases gradually with age, when women enter menopause the function of ovaries decreases and the level of estrogen decreases, so clinically vulvar laxity can occur. It is recommended to keep the vulva clean after menopause in daily life to avoid infection, and it is also recommended to insist on doing anal lifting exercises.
