Postmenopausal patients with bacterial vaginitis may be asymptomatic, or they may have symptoms such as increased vaginal discharge and vulvar itching. Usually the symptoms of postmenopausal bacterial vaginitis are the same as those of premenopausal bacterial vaginitis, with about 10-40% of patients having no clinical symptoms. In some symptomatic patients, there may be an increase in vaginal discharge, which is usually grayish-white, thin, with a fishy odor, and the symptoms may worsen after sexual intercourse. Some patients may also experience itching or burning of the vulva. If the patient is not actively treated and the condition gradually worsens, complications such as abnormal uterine bleeding may be induced. Endometritis and pelvic inflammatory disease may also be induced, with corresponding symptoms. Therefore, patients should pay more attention to vulvar cleansing and avoid using alkaline substances to wash the vulva and vaginal douche to avoid aggravation of symptoms. During the treatment period, patients should also prohibit sexual intercourse and pelvic baths. It is recommended that postmenopausal patients should be alerted to the possibility of bacterial vaginitis when the symptoms mentioned above occur, and if the diagnosis is clear, active treatment is needed.
