Diverticular bleeding happens when small pouches (diverticula) in the colon wall start to bleed. These pouches develop over time�often after age 40�and if a blood vessel within one ruptures, you may notice bright red or maroon blood in your stool.
He reviews your bleeding episodes, past colon issues, medications (especially blood thinners or NSAIDs), diet, and family history, then performs a focused abdominal and rectal exam.
Complete blood count to assess hemoglobin/hematocrit for anemia, coagulation studies to check bleeding risk, and basic metabolic panel.
Performs a colonoscopic evaluation to identify and potentially treat the bleeding diverticulum directly with clips or thermal therapy.
Selective mesenteric angiography can pinpoint the bleeding vessel and allow embolization to stop the bleed in severe cases.

It usually stops within 1�2 days. Dr. Chadha will keep a close watch and intervene if needed.
It can be if bleeding is heavy or recurrent. Prompt diagnosis and treatment help prevent complications.
Rest, stick to a clear-liquid or light diet, stay hydrated, and avoid NSAIDs. Seek medical care for heavy bleeding.
Diverticular bleeding is painless and comes from the colon. Hemorrhoids often cause pain, itching, or discomfort around the rectum.
You may see bright red or maroon blood in the toilet or on your stool, often without pain.
Yes. A colonoscopy locates the bleeding diverticulum and allows for treatment such as endoscopic clipping.
Eating a high-fiber diet helps reduce pressure in the colon but doesn�t eliminate all risk.
Endoscopic clipping is very safe. Rare side effects include infection or a small tear; Dr. Chadha's team takes every precaution.
Most patients feel better and return to normal activities within 1�2 days after bleeding stops or is treated.
