What does yellowish-green vaginal discharge indicate?

Leukorrhea refers to the normal vaginal discharge in women, composed of transudate from the vaginal mucosa and secretions from the cervical glands and endometrial glands. Under normal circumstances, the quantity and consistency of leukorrhea vary throughout the menstrual cycle, and its characteristics can reflect a woman’s overall health status. So, what does yellowish-green leukorrhea indicate? Below, we address this question.

What Causes Yellowish-Green Leukorrhea?

1. Candidal (Yeast) Vaginitis

Yellowish-green leukorrhea is commonly caused by candidal vaginitis. The hallmark symptoms of this condition include yellow or greenish discharge, increased volume, and a curd-like (cheese-like) appearance—typically white or pale green in color. Patients often experience intense vaginal itching, along with redness, swelling, and even ulceration of the vaginal mucosa, primarily due to infection with Candida albicans. Transmission occurs mainly through sexual contact, as well as indirectly via shared bathing facilities or towels. This condition is especially prevalent among women who have undergone prolonged hormone or antibiotic therapy, and among those with diabetes.

2. Trichomoniasis (Trichomonal Vaginitis)

Yellowish-green leukorrhea may also result from trichomoniasis, which is caused by the protozoan parasite Trichomonas vaginalis. Transmission occurs primarily through sexual intercourse or indirectly via contaminated objects. In trichomoniasis, leukorrhea increases markedly in volume and changes in color—from normal, translucent white discharge to grayish-yellow or yellowish-green, thin, frothy, curd-like discharge. Occasionally, blood-tinged streaks may appear within the discharge.

3. Chronic Cervicitis

Yellowish-green leukorrhea can also be associated with chronic cervicitis. This condition may cause small amounts of blood streaking in the discharge and an overall increase in discharge volume. Besides abnormal leukorrhea, patients may experience lower abdominal pain, dysuria (painful or difficult urination), dysmenorrhea (painful menstruation), and menstrual irregularities. Diagnosis is typically confirmed through cervical examination. Therefore, it is advisable to wash underwear separately, minimize use of sanitary pads, and avoid overuse of external genital cleansing solutions—which may disrupt the natural microbial balance of the vulva and predispose to gynecological disorders.

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