If a woman has white fluid coming out of the vagina, consider the presence of secretions, also known as leukorrhea, because leukorrhea can be affected by changes in the menstrual cycle, as well as by the estrogen and progesterone secreted by the ovaries, which can increase or decrease secretion at this time and produce certain changes in color. The leucorrhea is a viscous white liquid, which is a mixture of the vestibular gland, cervical glands, including endometrial secretion and vaginal mucous membrane exudate, as well as shed vaginal epithelial cells, so some women will have physiological leucorrhea with colorless, clear and white liquid, without any odor, without causing vulvar itching or uncomfortable symptoms, which is a normal physiological phenomenon. It is best to wash your vulva and change your underwear every day in your normal life. When there are uncomfortable symptoms, such as itchy vulva and odorous leukorrhea, you need to go to the hospital in time to avoid aggravating the performance of vaginitis.
