The primary treatment for vaginitis involves the use of local vaginal medications to improve the vaginal environment. Some cases also require oral medication for systemic treatment, but the crucial factor is identifying the type of vaginitis. For example, bacterial vaginitis can be treated primarily through oral medications, but local vaginal treatment is also an option. Yeast infections primarily involve local treatment with vaginal medications to alleviate symptoms. If there is no sexual activity and vaginal medication is unsuitable, oral medication can be used for systemic treatment. Trichomoniasis is mainly treated with oral medication for systemic treatment and should not be treated with local vaginal medications. Some types of vaginitis in elderly women can also be treated with local applications of estrogen cream or oral medication to supplement systemic estrogen therapy. Therefore, the main treatment methods for vaginitis depend on the specific type of infection.
