Due to the presence of lactobacilli in the vagina, the normal pH of leukorrhea in women is around 4-4.5. A high pH is alkaline and indicates a dysbiosis of the vaginal flora. If the pH of the leukorrhea is high, it can be regulated through lifestyle care and the application of appropriate medications. In the first case, a high pH level without vaginal inflammation can be seen in women who have frequent sexual intercourse, vaginal irrigation and abuse of broad-spectrum antibiotics, so we should actively remove the causes, control sexual intercourse, avoid vaginal irrigation and stop using antibiotics. Also pay attention to the hygiene of menstruation and sexual life, use loose underwear, preferably not disposable, non-breathable underwear, and avoid pantyhose as much as possible. If the pH is particularly high, you can apply lactobacillus capsules for vaginal use in moderation to help restore the vaginal environment, or apply bitter ginseng gel in the vagina to regulate it, and the pH may drop after recovery. In the second case, if the pH is very high and there is a combination of vaginitis, the treatment should be based on the classification of vaginitis. If it is bacterial vaginosis, you can take oral metronidazole or tinidazole or apply metronidazole suppositories intravaginally. In the case of mycosis vaginalis, vaginal suppositories for mycobacteria, such as clotrimazole, nifurtimox or mycobacterial suppositories, should be applied. In case of trichomoniasis, both husband and wife should take oral metronidazole or tinidazole at the same time. During the treatment period, it is important to prohibit sexual intercourse and pay attention to the cleanliness of the vulva in daily life and actively cooperate with the doctor in the treatment.
