Patients with bleeding stools with red mucus may have the following causes: First, inflammatory lesions: the above-mentioned symptoms occur when bacterial dysentery, ulcerative colitis, Crohn’s disease, intestinal tuberculosis and other co-infections are present. Second, malignant tumors: such as colon cancer, rectal cancer, etc., usually also accompanied by general wasting, weakness and other symptoms of wasting disease. If you find bleeding stool with red mucus, it is recommended to go to a regular specialized hospital for systematic examination in time to make a clear diagnosis. Be sure to rule out symptoms due to malignant tumors first, because this will be troublesome to treat if delayed.
