A white blood cell (++) or less in a routine white blood test is within the normal range, but if it exceeds (++), for example (++++) or (++++), it clinically indicates inflammation of the vagina. Because white blood cells appear to engulf pathogenic bacteria when they are present in the vagina, they will increase when inflammation is present. When inflammation of the vagina is detected, it is important to give active treatment. In addition to vaginal plugs, it is also recommended to keep the vulva clean in daily life and to change underwear regularly, pay attention to the hygiene of menstruation and sexual life, and change sanitary napkins regularly to avoid infection by pathogenic bacteria. It is also recommended that women eat less spicy and acidic foods and stimulating foods in their daily life to avoid vaginal inflammation to some extent.
