If the increase in discharge is accompanied by vulvar itching and odor, it is caused by inflammation and may be cervical lesion, etc. Vaginal discharge can be examined and colposcopy is also needed to determine if the vaginitis is caused by fungal, trichomonas or bacterial infection. If it is caused by inflammation, topical lotions and suppositories can be used. Cervical lesions need to be treated according to the HPV and TCT results.
