Bacterial vaginitis is caused by the proliferation of anaerobic bacteria such as Gardnerella, Actinobacillus and others. It is recommended to apply medication under the guidance of a professional doctor. The vagina is an environment with bacteria, when the normal lactobacillus and anaerobic bacteria such as Gardnerella and Campylobacter are in balance, it won’t lead to the occurrence of vaginitis, but if the local balance is broken and the pathogenic bacteria multiply, it will lead to the occurrence of bacterial vaginitis. Meanwhile, for women who have frequent sexual life, do not pay attention to personal hygiene, have bad habits such as smoking, drinking alcohol, or have multiple abortions, removal of the IUD, IUD and other uterine operations, the chances of bacterial vaginitis are higher than the general population. For women with bacterial vaginitis, it is recommended that they go to a regular hospital to complete a leukorrhea test to understand the vaginal environment, and under the guidance of the doctor to actively fight infection, but also pay attention to rest and strengthen exercise to improve resistance.
