The leukorrhea is light green and may be caused by bacterial vaginitis or trichomoniasis, which should be treated with medication according to the specific situation. If it is bacterial vaginitis, you can use metronidazole suppositories or diazoxide suppositories in the vagina. It is also recommended to douche the vagina with cleanser, pay attention to a light diet during treatment and not to eat spicy and stimulating food. If there is an abscess in the pelvic cavity, the leucorrhea may also appear light green. You can check it by ultrasound and take anti-inflammatory drugs such as amoxicillin and cefoxitin under the guidance of a doctor.
