A few patients with bacterial vaginitis have no clinical symptoms, and those who do have symptoms show an increase in the amount of leukorrhea compared to the usual amount, which is grayish-white, frothy, homogeneous, thin, or paste-like in color, and often adheres to the vaginal wall. Sometimes it is accompanied by mild vulvar itching and burning sensation, some people also have symptoms of urinary discomfort, such as frequent urination, urinary urgency, painful urination. If bacterial vaginitis is combined with other types of vaginitis, such as mycotic vaginitis and trichomonas vaginitis, the characteristics of the leukorrhea are not very obvious, so it is necessary to test the leukorrhea routine to clarify the type of vaginitis, and then symptomatic treatment. Usually pay more attention to wear cotton breathable underwear, change frequently, wash the vulva in time, sexual life should not be too frequent, to prevent the occurrence of bacterial vaginitis.
