Introduction
1. It may be caused by cervical disorders, the most common of which are cervicitis and cervical ectropion (previously termed “cervical erosion”).
2. Greenish vaginal discharge may result from bacterial vaginosis, a mixed infection typically involving *Gardnerella vaginalis* and certain anaerobic bacteria.
3. Trichomonas vaginitis—green-tinged vaginal discharge may also be attributable to trichomoniasis.
Normal vaginal discharge is typically clear or slightly milky white. If the discharge appears greenish, this warrants immediate attention, as it is commonly associated with infection. Prompt medical evaluation and relevant diagnostic tests at a hospital are strongly advised. Below, we address the question: “What causes green vaginal discharge?”
Causes of Green Vaginal Discharge
1. Cervical disorders—such as cervicitis or cervical erosion—may cause greenish discharge.
2. Bacterial vaginosis: This condition results from a mixed infection involving *Gardnerella vaginalis* and certain anaerobic bacteria, disrupting the normal vaginal microbial balance. It leads to increased vaginal secretions, fishy-smelling discharge, and symptoms such as pruritus and burning sensation in the vulva.
3. Trichomoniasis: Green-tinged vaginal discharge may indicate trichomoniasis, which can be effectively treated with topical antimicrobial therapy.
4. Chronic cervicitis or endometritis: Greenish or yellow-green, purulent, thick vaginal discharge may reflect chronic cervicitis or endometritis.
5. *Gardnerella* vaginitis (also known as haemophilus vaginitis): Clinical features include vulvar erythema and swelling, vaginal mucosal hyperemia appearing grayish-red, mild edema, and abundant homogeneous, thin, gray-white discharge—sometimes yellowish or greenish—with a characteristic foul odor.
The above outlines the potential causes of green vaginal discharge. We hope this information is helpful to you.
