The surface of the female vaginal mucosa is squamous epithelium, which is affected by female sex hormones and undergoes periodic shedding, which has a protective effect. At the same time, the squamous epithelium secretes glycogen, which is broken down into lactic acid by the lactobacilli that live in the vagina, thus maintaining an acidic environment in the vagina and inhibiting the growth and reproduction of bacteria. Under normal circumstances, women are not advised to do excessive vaginal douching, which is not beneficial in maintaining the acidic environment of the vagina, but can lead to dysbiosis, which can lead to vaginal inflammation. Celiac disease is not caused by bacterial infection. If you apply antiseptic, antiseptic, anti-itch and anti-inflammatory lotions to douche the vagina, it may destroy the protective barrier of the vagina itself, which is not beneficial to celiac disease and may cause secondary vaginal infections. Therefore, if celiac disease is not accompanied by vaginal inflammation, the application of local vaginal douches is not advocated.
