Bacterial vaginosis in some women may gradually improve after the end of their menstrual period, but for others, it does not ease and may even worsen. In such cases, medication is generally required. The occurrence of bacterial vaginosis is mostly due to the disruption of the vaginal environment's balance, causing some bacteria in the vagina to become pathogenic, thus leading to bacterial vaginosis.

The disruption of the vaginal environment's balance caused by bacterial vaginosis is mainly due to a significant decline in the body's immunity and resistance, which often drops during menstruation. When the menstruation ends, and the body's immunity and resistance gradually recover, bacterial vaginosis may also gradually ease. This recovery is more likely in cases of bacterial vaginosis that are asymptomatic. However, for those with obvious symptoms and severe discomfort from bacterial vaginosis, relief is hard to achieve after menstruation ends, and medication is generally needed in such cases.
