Vaginal cleanliness is clinically more severe if it is IV. In laboratory examination of the leukorrhea, the cleanliness is determined mainly by the amount of leukocytes, i.e. the cleanliness is highest in the case of leukocytosis, and the higher the cleanliness indicates more serious inflammation. Therefore, this condition should be treated clinically, for example, by inserting diazotide suppositories into the vagina or by inserting compound metronidazole suppositories into the vagina. During the treatment period, you should not have sexual intercourse and try not to eat spicy and sour food or stimulating food to avoid aggravating vaginal inflammation. If the cleanliness is still not below degree II, you can continue the treatment with medication.
