Under normal circumstances, bacteria are present in a woman’s vagina, mostly Lactobacillus, such as Lactobacillus curvatus and Lactobacillus jenneri. These bacteria are not densely distributed in the vagina and generally do not cause disease. These bacteria maintain a dynamic balance inside the vagina and work together to maintain a normal pH level inside the vagina. When a woman’s internal environment is changed or her immunity is lowered, it will result in an imbalance of the vaginal flora, and the normal bacteria may be transformed into disease-causing bacteria, leading to the occurrence of inflammation of the vagina. Therefore, women should pay attention to the hygiene of their private parts and clean them regularly to prevent the vaginal flora from being disorganized. If there is any discomfort, you should go to the hospital immediately.
