Symptoms of bacterial vaginitis mainly include increased vaginal discharge, itching or burning sensation of the vulva, which is mainly due to the imbalance of the normal flora in the vagina. 1. Increased vaginal discharge: the discharge often has a fishy odor and is thin. The discharge is grayish-white in color and uniform in appearance, and often adheres to the vaginal wall, but it is relatively easy to wipe away from the vaginal wall. 2. Vulvar itching or burning sensation: due to repeated vaginal douching, too much sex leading to mixed bacterial infections, micro-ecological imbalance of the vaginal flora, other microorganisms reproduce in large quantities, stimulating the vaginal wall to produce itching or burning symptoms. This symptom is often mild, but may worsen after sexual intercourse. If the above symptoms occur, it is recommended to go to the hospital in time and follow the doctor’s instructions for standardized treatment.
