What does it mean when vaginal discharge is green?
Healthy, normal vaginal discharge is odorless and appears white or creamy white. If the discharge turns greenish, this warrants immediate attention, as it often indicates an infection—commonly vaginitis or pelvic inflammatory disease (PID). Additionally, tubal obstruction accompanied by inflammation may also cause greenish discharge. This is frequently associated with a foul odor. Below, we discuss these conditions in detail.

What Causes Green Vaginal Discharge?
1. Fallopian Tube Obstruction
Fallopian tube obstruction can lead to abnormal vaginal discharge. Prolonged obstruction often triggers tubal inflammation, resulting in yellowish-green discharge accompanied by a fishy odor.
2. Vaginal Infection
Vaginal infections are commonly caused by inadequate personal hygiene. When pathogenic bacteria enter the vagina, they trigger infection, causing inflammatory secretions to mix with vaginal discharge—resulting in yellowish-green discharge. Prompt medical evaluation and treatment are essential to prevent progression to severe vaginitis.
3. Pelvic Inflammatory Disease (PID)
Abnormal vaginal discharge—particularly yellowish-green—is a common symptom of PID. PID typically arises from bacterial spread from the vagina into the pelvic cavity, leading to inflammation of pelvic reproductive organs and consequent changes in discharge color and consistency.
The above outlines potential causes of green vaginal discharge. Any persistent yellowish-green discharge should prompt timely medical consultation. As the condition worsens, the accompanying fishy odor intensifies—potentially causing significant social and occupational embarrassment. Therefore, delays in seeking care are strongly discouraged.
