Vulvitis generally results in abnormal vaginal discharge, primarily characterized by abnormal secretions causing itching and odor in the vulva. Normally, vaginal discharge in women is clear, transparent, odorless, and minimal, which is considered normal. If the discharge has an odor, it most commonly suggests a bacterial infection or a trichomonas infection. In cases of trichomonas infection, the discharge typically has a fishy smell, is watery, and accompanied by itching, leading to vulvitis reactions. At this point, a secretion test at the hospital can be conducted, followed by targeted treatment based on the test results. Furthermore, bacterial vaginitis can also present with odorous discharge. This condition typically involves yellow, thick, abundant discharge, and vulval itching. Treatment can then be tailored based on examination results, selecting appropriate topical medications. (Medication should be used under the guidance of a doctor.)
