The treatment of bacterial vaginitis is mainly to choose anti anaerobic drugs, including metronidazole, tinidazole and clindamycin. Because metronidazole can inhibit the growth of anaerobic bacteria without affecting the growth of lactobacillus, it is an ideal therapeutic drug. However, the specific medication method and dosage should be used under the guidance of the doctor. You should not blindly use the drug yourself, which may not alleviate the disease, but may aggravate it. The clinical manifestations of bacterial vaginitis are mainly the increase of thin vaginal secretions with fishy odor, which can be accompanied by mild vulval pruritus or burning sensation. After sexual life, the symptoms become worse, and the secretion has fishy odor, which is caused by amine substances produced by anaerobic bacteria. The vaginal mucosa was checked for no obvious signs of inflammation such as congestion. The secretion was grayish white, uniform, thin, and often adhered to the vaginal wall.
