Normal leukorrhea is milky white and remains milky white even after it dries on your underwear. If the leukorrhea on the underwear is yellow, bloody or any other color, it is clinically abnormal, often due to vaginal inflammation, cervical inflammation, endometrial inflammation or pelvic inflammation, which may cause leukorrhea to appear abnormal in color. It is recommended to go to the hospital for timely examination to rule out the possibility of the above diseases, and it is best to do routine tests on the leukorrhea to understand the pathogens or causes of the yellowing of leukorrhea, and give active treatment. In addition, it is recommended that women keep the vulva locally clean in their daily life to reduce the infection of pathogenic bacteria, and pay attention to the hygiene of sexual life and menstruation to avoid the possibility of causing inflammation of the reproductive tract.
