Normal or abnormal secretions from the vagina. Mucus produced by the cervical glands is discharged from the vagina naturally, especially during the childbearing years. Causes of abnormal vaginal discharge include infectious agents (e.g., Neisseria gonorrhea, Chlamydia trachomatis, Trichomonas, and Candida albicans), the presence of foreign bodies, and cervical or vaginal cancer.
