When a woman has fewer PCs in her routine leukorrhea test, it means that she has fewer inflammatory cells in her vagina, which is a normal phenomenon that proves that she has the right amount of lactobacillus bacteria in her vagina, and that the environment in her vagina has a self-purifying and cleansing effect by itself. If the PC cells are more women, there are more bacterial infections in the vagina, need to pay attention to whether there are trichomonas, mold or clue cell growth, need to give lotion and medication for treatment. Women in general should also pay attention to keep the vulva clean, hygiene, daily replacement of underwear, in the sun, due to women’s vulva and urethra, anus proximity, can easily lead to local bacterial infections occur, so be sure to pay attention to their own cleanliness, and do not eat spicy, stimulating food on the diet, appropriate exercise, in favor of reducing bacterial infections.
