When a woman has white dirt on her labia majora, it is necessary to determine what causes it depending on the specific situation. In the physiological state of women’s vaginal secretions, the amount and nature of the different stages of the menstrual cycle is not the same. For example, during ovulation the estrogen level in the body rises, and the leukorrhea increases and takes on a strained appearance. If you don’t pay attention to washing the vulva, leukorrhea accumulates in the vulva, and white dirt is formed when the water evaporates. It is usually not accompanied by other symptoms, and is only discovered by chance. Some women may suffer from gynecological inflammation, such as pelvic inflammatory disease, vaginal inflammation with increased vaginal discharge, white dirt appearing on the labia majora, often accompanied by other symptoms, such as discharge with a bad smell, vulvar itching, vulvar congestion, edema, elasticity decreases, and pain caused by intercourse.
