A normal leukorrhea is white, milky or clear and odorless. A change in the nature of the leukorrhea is usually associated with gynecological inflammation. When the leukorrhea turns green, it is usually considered to be related to bacterial vaginitis or trichomoniasis. In bacterial vaginitis, the leukorrhea is yellow or yellowish-green with a fishy odor. In trichomoniasis, the leukorrhea may be white or green with a frothy consistency, accompanied by a foul odor and itching of the vulva. Women with cervical disease, such as severe cervical erosion, can also cause changes in the color of the leucorrhea. It is recommended to go to the hospital for a comprehensive gynecological examination and routine leucorrhea, as well as annual cervical cancer screening, according to the results of the examination for symptomatic treatment, and usually pay attention to the cleanliness of the vulva and vagina.
