Introduction
In females, excessive vaginal discharge is commonly pathological—for example, chronic cervicitis, vaginitis, or endometritis. Inflammation can stimulate cervical glands, leading to a marked increase in vaginal discharge; in severe cases, the discharge’s color may also change. Additionally, patients often experience pruritus and pain in the external genitalia, necessitating prompt diagnosis and treatment.

Most women experience relatively minimal vaginal discharge. However, it is normal for discharge volume to increase during ovulation or just before menstruation. In contrast, a small number of women may consistently experience excessive vaginal discharge. So, what causes excessive vaginal discharge in women?

What Causes Excessive Vaginal Discharge in Women?

Excessive vaginal discharge in women is commonly due to pathological conditions, such as chronic cervicitis, vaginitis, or endometritis. Inflammation stimulates the cervical glands, leading to markedly increased discharge. In severe cases, the color of the discharge may also change. Additionally, symptoms such as external genital itching and pain often accompany the condition, necessitating prompt medical evaluation and treatment.

Furthermore, increased vaginal discharge commonly occurs during the menstrual cycle. After entering the menstrual phase, discharge volume rises in parallel with increasing estrogen levels. Typically, estrogen levels gradually rise one day prior to ovulation, resulting in progressively increased cervical mucus secretion. Consequently, vaginal discharge peaks just before ovulation.

Sexual activity can also trigger increased vaginal discharge. Since sexual activity is hormonally driven by estrogen, each episode prompts a systemic mobilization of estrogen. As sexual activity progresses and sexual arousal intensifies, estrogen levels transiently rise. This neuroendocrine reflex significantly boosts the production of secretions—a normal physiological response.
