A sudden increase in leukorrhea is usually seen in physiological leukorrhea, such as in women in the periovulatory period, and may also be caused by vaginal inflammation. If the increase is physiological, manifested as increased leucorrhea, no odor, no vulvar itching, no vaginal or vulvar pain, and a stretched discharge, this situation is considered to be related to the rise of estrogen level in the body, and no special treatment or therapy is needed. If there is an increase in leucorrhea with vulvovaginal itching and odor and yellow, beanbag-like or foamy discharge, further laboratory tests of vaginal discharge are needed. Based on the results of the vaginal discharge test, the next step of treatment will be decided.
