Vaginal odor is not normal. Normally, women’s leukorrhea is clear, transparent, odorless and in small amounts. If there is an odor, most of them indicate vaginal inflammation. When there is trichomonas infection, the leucorrhea will be watery, with a fishy odor, and itching will be obvious and will increase at night. If the leucorrhea is yellow, sticky and has an odor, this situation overwhelmingly suggests the possibility of bacterial infection, and the patient can go to the hospital to take a laboratory test of the secretions, which can clarify the diagnosis. Bacterial infections can be treated symptomatically according to bacterial vaginitis. Vaginitis infection has different bacteria, different clinical manifestations, and different medications.
