Women with serious lower body odor are mostly caused by vaginal inflammation or vulvovaginal inflammation, and may also be caused by mycoplasma or chlamydia infection. If there is chronic cervicitis, cervical precancer, or even cervical cancer, there may also be odor. In addition, if you have endometrial cancer or ovarian cancer, you may also have vaginal discharge odor or even bad smell. It is better to come to the hospital for routine white belt and gynecological examination, and cervical cancer examination if necessary. If it is really inconvenient to come to the hospital, you can use the medicine empirically for a short period of time. If you are not a virgin and do not intend to get pregnant in the near future, you can take one oral metronidazole tablet in the morning and one in the evening for one week, and use metronidazole suppositories to plug the vagina for one week. If the symptoms do not improve significantly or worsen after a week of medication, it is best to come to the hospital in time.
