Stools with live blood are a sign of bleeding in the lower region of the digestive system (large intestine, rectum and anus). The most frequent causes are due to lesions in the anus (anal fissures) and hemorrhoids, which usually bleed in situations that require effort to evacuate (constipation). Other causes of bleeding include polyps, diverticuloses, worms, infectious and inflammatory bowel diseases (colitis, Crohn's disease, ulcerative colitis) and tumors.
Constipation can be relieved by ingesting more fluids and maintaining a healthy diet with lots of fruits, vegetables and fiber. Regular physical activity, such as walking, stimulates bowel movement, improving constipation.
The gastroenterologist or the proctologist are the medical specialists appointed to perform the diagnosis and treatment of problems of the digestive system, as in the case of blood in the stool.
