What does yellow-green vaginal discharge indicate?

Normal vaginal discharge (leukorrhea) is typically milky white or colorless and transparent, with a faint fishy odor or no noticeable odor. When abnormalities occur, its appearance, consistency, and odor may change significantly. Yellowish-green vaginal discharge is a symptom of gynecological disease, generally resulting from infection of vaginal secretions, leading to an abnormal alteration in discharge characteristics. So, what does yellowish-green vaginal discharge indicate? Below, we address this question.

What Does Yellowish-Green Vaginal Discharge Indicate?

1. Trichomoniasis Vaginitis

Yellowish-green vaginal discharge in women often suggests trichomoniasis vaginitis. This condition typically causes increased discharge volume, which may appear greenish-purulent or thin, grayish-white or yellowish, and is usually accompanied by a pronounced foul odor. Patients may also experience itching of the vulva and vagina; in severe cases, burning pain may occur.

2. Fungal (Candidal) Infection

Women with fungal infections may also develop yellowish discharge, often presenting as curd-like (resembling cottage cheese). This is one of the hallmark features of candidal vaginitis. Therefore, when yellowish-green discharge appears alongside a curd-like consistency, a fungal infection should be strongly suspected. We recommend routine vaginal discharge examination, cervical secretion pathogen culture, and pelvic ultrasound to help confirm the diagnosis.

3. Endometritis

Endometritis is another potential cause of purulent greenish-yellow vaginal discharge. Women who have recently given birth or undergone abortion are at higher risk for developing endometritis—a relatively serious infection. Thus, if greenish-yellow discharge occurs shortly after childbirth or abortion, prompt medical evaluation and treatment are essential.

The above outlines possible causes of yellowish-green vaginal discharge. We hope this information is helpful to you.
