Discharge from your underwear every day is a normal sign if the discharge has no odor and is of normal color. However, if the discharge has a fishy or other odor, or is accompanied by a change in color or character, it may be a condition such as vaginal inflammation. 1. Normal situation: If you find that there is discharge on your underwear every day, but the color of the discharge is normal and there is no smell, and the patient does not have any uncomfortable symptoms, this may be normal. 2. Vaginal inflammation: (1) Vulvovaginal pseudomycosis: If the patient has more discharge, which is white and pea-like, or accompanied by vulvar itching, it may be caused by vulvovaginal pseudomycosis. (2) Bacterial vaginosis: if the patient has increased discharge, the color of the discharge is grey or yellow-green, and there is an abnormal fishy odor, it may be due to bacterial vaginosis. (3) Trichomonas vaginitis: If the patient has increased discharge, which is thin and purulent with foam, it may be trichomonas vaginitis caused by trichomonas infection. If a woman has more secretions on her underwear, accompanied by color changes and abnormal smell, she should go to the hospital in time to improve the relevant examinations, and give targeted treatment after clarifying the cause under the guidance of professional doctors.
