Vaginal flora shift is a disruption of the vaginal ecosystem that changes the vaginal flora from a balanced state to the presence of one or more dominant bacteria, resulting in vaginal flora imbalance. Under normal circumstances, a certain number of bacteria are present in the vagina. However, these bacteria will restrain each other and maintain a state of balance. If the internal vaginal environment is damaged, such as too much sex, excessive vaginal douching or irregular vaginal drug administration, etc., it will kill the normal vaginal flora and lead to the overgrowth of harmful bacteria, resulting in dysbiosis. The phenomenon of the vaginal flora changing from a relatively balanced state to an overgrowth of one or several dominant flora is the vaginal flora transition. Vaginal flora shift can lead to bacterial vaginitis, moldy vaginitis, fungal vaginitis and other vaginal inflammatory diseases. If you experience vulvar itching and increased vaginal discharge, it is recommended that you consult a doctor in a timely manner to clarify the cause and then proceed with targeted treatment and management.
