Fishy vaginal discharge is mainly associated with uterine infections or chronic cervicitis. It usually manifests as increased vaginal discharge, which is purulent, with a fishy odor and sometimes yellow or greenish. This usually means that there are bacteria, viruses, trichomonas, mycoplasma and other special flora in the body. Therefore, anti-inflammatory treatment such as topical metronidazole tablets and oral metronidazole tablets to fight against anaerobic bacteria, as well as antibacterial gel and mycoplasma should be used to control the progress of the disease to prevent the emergence of cervical erosion, cervical cancer and other adverse consequences. Washing the vulva with warm water every night before going to bed can be a good way to avoid the growth of bacteria.
