###Human: Could bleeding ulcer be the reason for anal bleeding? ###Assistant: Hello. I can understand your concern on this issue. The photograph which you uploaded indicates fresh blood in minute quantity (attachment removed to protect patient identity). Fresh blood from the anus on the surface of stool or without passing stool indicates a lesion in the lower part of the anal canal. Most common lesion in this area that bleed is anal fissure in which there will be a linear tear on the inner wall of the lower part of the anal canal. Bleeding occurs generally from this tear while straining to pass stool. Constipation is the risk factor for development of a fissure. Bleeding ulcer also produces other symptoms such as mucus discharge, liquid consistency of stool and increased stool frequency. Constipation. Digital rectal examination and proctoscopy. Hemorrhoids. Anal fissure. Treatment for pain and constipation. Local ointment application for active bleeding from a fissure. For further information consult a medical gastroenterologist online.--->
