When the vulva smells bad, this is a sign of inflammation of the vagina, including failure to change underwear in a timely manner, with some urine and fecal contamination. Inflammation of the cervix, cervical naevus cysts, or inflammation of the endometrium can cause a bad odor. It is recommended to go to the gynecology department of the hospital for examination of vaginal secretions to exclude which kind of vaginal inflammation is present, and according to the situation, lotions, including vaginal plugs, should be prescribed. If there is cervical congestion or cervical erosion at the time of examination, it is recommended to carry out TCT and HPV cancer prevention examination to rule out the existence of human papillomavirus infection. Avoid the physical effects of persistent viral infections and frequent leukorrhea, which should be treated symptomatically at this time.
