Common causes of candidal vulvovaginitis include long-term use of broad-spectrum antibiotics, patients with diabetes, patients who long-term use immunosuppressive drugs, wearing tight underwear, and moisture in sanitary products. All these factors can lead to the occurrence of candidal vulvovaginitis.

Changing unhealthy lifestyles, stopping the use of antibiotics, actively treating diabetes, wearing breathable cotton underwear, and keeping the vulva clean can all reduce the occurrence of candidal vulvovaginitis.
