Vaginal pH of 4.6 is within the normal range. The pH level in women’s vagina is basically fixed, between 3.8 and 4.8 is the normal range. It is important for women to pay attention to vaginal cleanliness in their daily life and not to use random medications or cleansers to prevent vaginal pH from changing. The vaginal pH has a self-cleaning effect. When the pH balance is disrupted, the self-cleaning ability is weakened and the vaginal pH level is too high or too low, which can lead to inflammation. When the pH level is too high, women may experience increased leucorrhea and odor, and can take metronidazole or use compound red nucleus lotion to cleanse the vulva.
