###Human: My stool is often covered with bright red blood, and I feel fatigued. Why? ###Assistant: Hello dear, hope you are fine. The presentation you described is likely to be a hemorrhoids (biles), that causing blood in the stool. The fatigue you described maybe due to loss of blood, that caused anemia. I recommend that to confirm the diagnosis, to be examined by a surgeon, so to make sure it's only hemorrhoid, and no other masses there causing your symptoms. I also recommend to have blood test, CBC , so to check your hemoglobin. once diagnosis is confirmed, we will discuss the management (which mostly include having high fiber diet and oral laxatives).
