If the uterus prolapses in the first degree, it will only get more and more serious and will not retract on its own. However, if a patient with first-degree prolapse of the uterus can actively perform pelvic floor exercises under the guidance of a doctor, there is still a high possibility that the uterus will return to its original position. If the uterus is only a degree I prolapse, it means that the degree of uterine prolapse is not too serious. If the ectocervix is generally less than 4 cm from the hymenal edge, it is called mild first-degree prolapse. If the cervix has reached the hymenal edge and the cervix is visible at the vaginal opening, it is called heavy first-degree prolapse of the uterus. These two types of uterine prolapse are treated by pelvic floor muscle exercise and assisted biofeedback training, and the cure rate is very high with the usual exercise.
