When stool becomes dessicated within the diverticulum and forms a fecolith, it can press on the adjacent vessel and erode into it. The natural history of diverticular bleeding is that most episodes stop spontaneously and multiple episodes are common. It is important to document the source early by bleeding scan in case interventional radiology or surgery becomes necessary. Both diverticular bleeding and another source of colonic bleeding – ateriovenous malformation – are statistically more common in the right side of the colon.
