If a woman has bloody leukorrhea, there are two kinds of cases: physiological and pathological. Physiological leukorrhea with blood, common in the ovulation period, due to the decline in the level of estrogen caused by the endometrium part of the shedding of vaginal bleeding, accompanied by leukorrhea discharge and the presentation of leukorrhea, which lasts for two or three days after the disappearance of their own, can not be special treatment. Pathological hematochezia is common in severe cervical erosion, if not timely diagnosis and treatment, there will be a small amount of blood oozing from the surface of the erosion, and there will be contact bleeding during coitus, so there will be hematochezia, which requires timely specialist consultation and medication or physical therapy. Pathological blood is also seen in cervical cancer, endometrial cancer and other malignant lesions, the earliest clinical manifestation is blood in the leukorrhea, therefore, once women find blood, we should pay attention to, as soon as possible, leukorrhea routine, colposcopy, hysteroscopy and other examinations, to clarify the cause of the disease and then symptomatic treatment.
