What are the symptoms of bacterial vaginitis?

Symptoms of bacterial vaginosis typically include an abnormal increase in vaginal discharge, which may appear grayish-white or pale yellow in color and have a thin consistency, accompanied by a fishy odor. This unpleasant smell may worsen after sexual intercourse or physical activity, causing significant discomfort to the patient. Patients may also experience itching and a burning sensation in the external genitalia, and sometimes mild vaginal pain. These symptoms not only affect the patient's quality of life but may also cause difficulties during sexual activity. During diagnosis, physicians will also consider whether the patient has urinary symptoms such as frequent urination or urgency, as well as clinical signs like vulvar eczema caused by irritation from vaginal discharge—these are common clinical manifestations of bacterial vaginosis.
