The main function of Lactobacillus is to regulate the internal environment of the vagina to increase the local resistance and reduce the incidence of vaginal inflammation by reducing pathogenic bacteria. If Lactobacillus decreases, it may cause pathogenic bacteria to multiply and cause anaerobic infections or other bacterial infections that can cause vaginal inflammation. If lactobacillus (++) is tested in the leucorrhea, it is recommended to keep the vulva locally clean in daily life, don’t develop the habit of using pads, there is no pathogenic bacteria infection and no corresponding clinical symptoms, you should not rinse the vagina with the corresponding medicine as a nursing solution, it will change the normal flora in the vagina and make the resistance decrease, washing the vulva with water only is enough.
