Bacterial vaginosis may heal without medication in some women.

This is because bacterial vaginosis is a mixed infection caused by the imbalance of the normal vaginal flora. It is generally considered an endogenous infection. When a woman's immune system is strengthened, the vaginal flora can return to its normal environment, maintaining the balance and potentially healing without medication.

However, treatment is generally necessary if bacterial vaginosis presents with clear symptoms, such as a significant increase in vaginal discharge, accompanied by itching or a burning sensation in the vulva.
