Can a diverticulum bleed?
What is diverticular bleeding? Diverticular bleeding occurs when pouches (diverticula) that have developed in the wall of the large intestine (colon) bleed. If you have these pouches, you have a condition called diverticulosis. Diverticular bleeding causes a large amount of blood to appear in your stool.
What causes a bleeding diverticulum?
Pouches may form when the high pressure pushes against weak spots in the colon. Weak spots are where blood vessels pass through the muscle layer of the bowel wall to supply blood to the inner wall. Bleeding occurs when the blood vessel going to the pouch breaks open.
Can you have internal bleeding with diverticulitis?
Diverticular bleeding — When a small artery located within the diverticulum breaks through the colon lining and bleeds into the colon. This can happen with diverticulosis and diverticulitis. Diverticular bleeding usually causes painless bleeding from the rectum.
How often do diverticula bleed?
Diverticular bleeding occurs in 3 to 5% of patients with diverticulosis, with more than two-thirds of diverticular bleeding proven by demonstrating stigmata of recent bleeding on colonoscopy occurrence at or proximal to splenic flexure of the colon with a significant predilection to the right colon.
How serious is diverticular bleeding?

How is diverticular bleeding treated?
Endoscopic therapeutic maneuvers, such as epinephrine injection or electrocautery therapy, can be used to treat diverticular bleeding. Patients should avoid using aspirin and nonsteroidal anti-inflammatory drugs because of their association with diverticular bleeding.
How long does it take for diverticular bleeding to stop?
The mechanism behind colonic diverticular bleeding is not completely understood. CDH usually stops spontaneously in up to 90% of cases [32]. However, emergent colonoscopy should be considered within 24 h after admission in cases of CDH in order to identify the culprit diverticulum.
How do you stop a diverticula from bleeding?
Can stress cause diverticular bleed?
