Bacterial vaginitis usually does not heal on its own. It must be treated properly to recover. Bacterial vaginitis is a syndrome of increased vaginal discharge, fishy smelling leukorrhea and itching and burning vulva caused by a mixture of Gatnerella vaginalis and some anaerobic bacteria, resulting in an imbalance of the micro-ecological balance in the vagina. It will not recover without receiving regular treatment. Usually, the diagnosis can be made by testing routine leucorrhoea, which can detect clue cells and increased pH. Treatment is mostly given with medications for anaerobic bacteria, such as: oral metronidazole tablets, or topical metronidazole suppositories administered vaginally. The duration of treatment is at least one week. Sexual intercourse is prohibited during the treatment period. It is recommended to wear loose cotton underwear, change underwear regularly, and wash underwear separately from other clothes. Vaginitis is prone to recurrence. You can continue the medication for one week after menstruation to prevent recurrence. After the symptoms are stable, you can recheck the white belt routine to compare. If you are diagnosed with bacterial vaginitis, you should actively take treatment and follow your doctor’s advice.
