The main cause of odorous leukorrhea is vaginal inflammation, which requires the use of medication for vaginitis. Normal leukorrhea in women is odorless, but when infected by various bacteria, especially anaerobic bacteria, anaerobic enzymolysis occurs and produces putrid gas. In case of trichomoniasis, yellowish green frothy leucorrhea with fishy odor can be treated with oral metronidazole or with vaginal douching plus metronidazole suppositories. Since trichomoniasis can be transmitted through sexual intercourse, sexual intercourse should be strictly prohibited during the treatment period and oral metronidazole treatment is recommended for sexual partners at the same time. In case of bacterial vaginitis, there will be greyish-white vaginal discharge with fishy odor, which can be treated with medications such as Kang Women’s Gel and Clindamycin Phosphate Vaginal Gel along with vaginal douching. Regardless of the type of vaginitis, the medication should be used continuously for more than one week and the vaginal discharge should be checked after three days of stopping the medication, if there is no abnormality, the vaginal discharge can be judged as cured.
