Does vaginal discharge increase before menstruation?

Yes, vaginal discharge often increases before menstruation. This is due to pelvic congestion that occurs in preparation for menstruation. When pelvic congestion intensifies, blood flow to the cervix and vagina increases, leading to greater vaginal discharge. Such premenstrual discharge elevation is generally a normal physiological phenomenon and does not warrant excessive concern. In most cases, no medical evaluation is necessary. Typically, premenstrual discharge is more abundant than usual, appearing colorless, transparent, or white, and may occasionally have a fishy odor—though this odor usually subsides as menstruation begins and discharge volume decreases.

Premenstrual symptoms vary depending on individual physical constitution. Some women experience no symptoms at all, while others may develop premenstrual syndrome (PMS), manifesting as headache, fatigue, irritability, tension, lower back pain, abdominal discomfort, or other symptoms. Overall, premenstrual symptoms differ from person to person and typically resolve spontaneously after menstruation.

Patients should consume light, bland foods and avoid spicy or irritating foods. Smoking and alcohol consumption are strictly prohibited. Increased discharge may also indicate underlying pathological conditions such as vaginitis, cervicitis, pelvic inflammatory disease, cervical cancer, or endometrial cancer. Therefore, patients are advised to seek timely medical evaluation to prevent delays in diagnosis and treatment. We hope this information is helpful. Wishing you good health and happiness!
