Causes of Green Vaginal Discharge
Vaginal discharge (leukorrhea) is one of the normal physiological phenomena in women. Its appearance can directly reflect a woman’s health status. If the discharge appears green or yellow, this indicates an abnormal condition requiring prompt medical attention. Green vaginal discharge is often directly associated with certain gynecological disorders and must never be ignored—doing so may lead to more serious complications. Below, we explore the possible causes of green vaginal discharge, hoping to raise awareness among readers.

Causes of Green Vaginal Discharge
1. Cervicitis
Green discharge may result from cervical disease, most commonly cervicitis or cervical erosion.
2. Bacterial Vaginosis
Bacterial vaginosis—caused by a mixed infection involving Gardnerella vaginalis and various anaerobic bacteria—disrupts the vaginal microbiome, leading to increased vaginal secretions, fishy-smelling discharge, and symptoms such as pruritus and burning sensation of the vulva.
3. Trichomoniasis
Slightly green vaginal discharge may indicate trichomoniasis, which can be effectively treated with topical medications.
4. Chronic Cervicitis or Endometritis
Abnormally green discharge may also signal chronic cervicitis or endometritis. In such cases, discharge is typically increased in volume and appears yellow or yellow-green, purulent, and viscous.
5. Gardnerella Vaginitis
Also known as Haemophilus vaginalis vaginitis, this condition presents with vulvar erythema and swelling, vaginal mucosal hyperemia (grayish-red appearance), mild edema, and abundant homogeneous, thin, gray-white discharge—sometimes yellowish or greenish-tinged, with a foul, fishy odor.
The above outlines the primary causes of green vaginal discharge. We hope this information proves helpful.
