This is the result of my routine leukorrhea test. What type of vaginitis is this exactly?
Is bacterial vaginosis the same as bacterial vaginosis??/

Doctor's answer:

Hello: You have bacterial vaginosis, which is very stubborn. Treatment requires persistence, and it is recommended to continue medication. The occurrence of vaginitis not only affects women's physical health but can also lead to gynecological diseases. Therefore, it is best to visit the gynecology department of a hospital for a vaginal examination. After identifying the cause, symptomatic treatment should be administered. Pay attention to dietary adjustments, consuming light and easily digestible foods, and avoid spicy, stimulating, and cold foods.
