Untreated vaginitis may lead to upstream infection, which can lead to endometritis and even uterine adhesions, which can lead to infertility. It may also lead to tubal inflammation, which can lead to blockage of the fallopian tubes and affect conception. It may lead to pelvic inflammatory disease, which may cause pain in the small abdomen and lumbosacral discomfort. If vaginitis is not treated effectively for a long time, it can also lead to chronic cervicitis, such as cervical polyps, cervical erosion, cervical hypertrophy, and cervical sodium sac. Therefore, women with vaginitis should be treated in time, otherwise it will cause serious harm to women physically and mentally.
