The pH of the leukorrhea 5.20 indicates the pH of a woman’s vagina, which should be ≤ 4.5. An acidic environment prevents other bacteria from growing and reproducing in it. pH 5.2 is obviously greater than 4.5, which means that the acidic environment of the vagina is declining, and this environment also tends to cause other bacteria to grow and reproduce in it, especially trichomonas, anaerobic bacteria and Gardnerella, so women should also Look at the white blood test for pathogenic infections. If there are none, but simply an elevated pH, this is the time for women to pay attention and wash their vulva with potassium permanganate drops every night, which can increase the acidity of the vagina. If there are these pathogenic infections, they need to be treated with the appropriate medication.
