The most common types of vaginitis are trichomoniasis and bacterial vaginitis. 1. If it is mycotic vaginitis combined with bacterial infection, yellowing of the leucorrhoea will also occur, so it is best to go to the hospital for an interview and to have the leucorrhoea tested. If it is trichomoniasis, it can be treated with metronidazole, which is effective both orally and vaginally. 2. If it is bacterial vaginitis and vulvar itching is not very serious, this vaginitis can be treated with oral clindamycin and lactobacillus can be placed in the vagina. If it is mycosis vaginalis, you can use clotrimazole or dacrynic pessary vaginally, the treatment effect is also very good. You must pay attention to the hygiene of your vulva, wear cotton, breathable underwear and put the sanitary products you use in the sun to reduce the occurrence of vaginitis.
