Bacterial vaginitis is a disease caused by a mixture of bacterial infections and the reduction or disappearance of vaginal lactobacilli, resulting in an increase in pH in the vagina. Bacterial vaginitis can be caused by any factor that can cause dysbiosis in the vagina, such as prolonged unclean sex, prolonged use of vaginal douches, and abuse of lotions. Bacterial vaginitis is usually treated with medication and most patients can be cured in about 7-14 days. However, bacterial vaginitis is prone to recurrence, so patients should adhere to the standard medication as prescribed by the doctor and should not stop taking medication without permission to avoid aggravating the condition. During the treatment period, sexual intercourse should be prohibited to avoid cross-infection. At the same time, spicy and stimulating food is prohibited, and you should eat a light diet, pay attention to personal hygiene and try to keep your vulva clean and dry.
