In most cases, the presence of coffee-colored stool is not considered bleeding and is directly related to the patient’s recent diet, which may have recently eaten dark-colored food, which in turn causes the stool to appear coffee-colored. If bleeding is present, it may be evident after a bowel movement, and this condition is mostly considered to be bleeding due to hemorrhoids. If there is no obvious blood, but simply blood in the stool, this situation is mostly considered to be intestinal lesions, intestinal lesions are mostly accompanied by abdominal distension, abdominal pain, diarrhea and other discomfort or mucus in the stool, increased frequency of defecation, mostly considered to be caused by enteritis or intestinal polyps, or even intestinal malignant tumors. If you have coffee-colored stool for a long time, accompanied by abdominal pain, diarrhea and other symptoms, you need to do a colonoscopy to exclude intestinal lesions. Usually, you should pay attention to a light diet and eat more fresh fruits and vegetables in season.
