Why could you have blood in your poop?

ANSWER

You may easily see it as red blood or black tar-like bowel movements, or it may be microscopic so you can’t see it. Blood may show up in your poop because of:

  • Growths or polyps of the colon
  • Hemorrhoids
  • Anal fissures
  • Intestinal infections that cause inflammation
  • Ulcers
  • Ulcerative colitis
  • Crohn's disease
  • Diverticular disease
  • Problems in the blood vessels in the large intestine
