Anal bleeding can be a sign of many different problems. Some causes can be serious, which is why it should be checked out by your doctor. Bright red blood may be seen only on toilet paper or in the toilet bowl after a bowel movement — not mixed freely with the bowel motion. This type of bleeding is usually caused by haemorrhoids piles or anal fissure. Blood mixed into the bowel movement usually means trouble further up from the anus: it may indicate an inflamed rectum or colon large intestine or bowel.
Bleeding from the anus
Rectal hemorrhage: Causes, Symptoms and Diagnosis
Rectal bleeding can refer to any blood that passes from your anus, although rectal bleeding is usually assumed to refer to bleeding from your lower colon or rectum. Your rectum makes up the last few inches of your large intestine. Rectal bleeding may show up as blood in your stool, on the toilet paper or in the toilet bowl. Blood that results from rectal bleeding is usually bright red in color, but occasionally can be dark maroon. Mayo Clinic does not endorse companies or products.
Rectal Bleeding: Possible Causes
Minor rectal bleeding refers to the passage of a few drops of bright red fresh blood from the rectum, which may appear on the stool, on the toilet paper or in the toilet bowl. This brochure addresses minor rectal bleeding that occurs from time to time. Continuous passage of significantly greater amounts of blood from the rectum or stools that appear black, tarry or maroon in color can be caused by other diseases that will not be discussed here. Call your doctor immediately if these more serious conditions occur.
