The occurrence of vaginal laxity is almost inevitable for women, but there are things we can do to delay and reduce its occurrence. Pregnancy and childbirth and ageing cannot be avoided, but there are some controllable factors that women should actively avoid, such as maintaining a reasonable weight through healthy practices, abstaining from smoking and alcohol, and actively treating chronic diseases such as cough and constipation. Adult women should make kegel exercise a lifelong necessity and perform correct and effective regular exercise. You can also undergo pelvic floor rehabilitation or intimate laser treatment in the hospital, which are usually very effective. If the current level of vaginal laxity is more severe, it can be treated with surgery. Due to the increased life expectancy of women, the occurrence of vaginal laxity in older women is very common. It is recommended that prevention be the main focus and that effective exercises for the pelvic floor muscles be performed throughout life and that such exercises become a part of life.
