Blood may arise from various diseases of the colon (large intestine) including diverticulosis and diverticulitis, inflammatory bowel disease (IBD), and arteriovenous malformations (AVM). Colon polyps, cancers, and other growths can also cause blood in the stool. When the blood supply to the colon is decreased or cut off, the colon can become inflamed and bleed. This can be caused by ischemic colitis (blood flow to the colon is decreased), intussusception (one section of the colon telescopes into another and volvulus, when the colon twists upon itself). Diverticular bleeds tend to be painless but there can be significant blood loss. Pain is the hallmark of blood loss in the colon.
