Common Causes and Risk Factors
Age over 50
Low-fiber diet
Straining and chronic constipation
Obesity or tobacco use
Frequent consumption of NSAIDs or anticoagulants
Signs and Symptoms
Sudden, acute, painless, maroon-colored or bright red blood in the stool
Mild abdominal pain and occasional cramping
Lightheadedness or dizziness in cases of heavy bleeding
In severe cases, rapid heartbeat (tachycardia) or low blood pressure (hypotension)
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Physical Exam
He investigates your bleeding history, your bowel movements, your diet, anything you are taking (especially non-steroidal anti-inflammatory drugs) and your risk factors, including age and fiber intake.
Blood Tests
A complete blood count (CBC) is carried out to assess anemia, whereas coagulation studies are carried out to assess the danger of bleeding and additional treatment.
Colonoscopy
Instantly reveals perforations and bleeding spots.
Offers immediate therapeutic options-clips or heat therapy to avoid bleeding.
CT Angiography
This scan is used in the case of excessive bleeding or continued bleeding and helps to locate the bleeding vessel and plan the interventional therapy.
Angiographic Embolization (Advanced Testing)
This is done by inserting a small catheter by a specially trained radiologist through a bleeding artery which delivers embolic substances to halt hemorrhage without open surgery.
Treatment
Our Team offers a full range of care for diverticular bleeding.
1. Diet and Lifestyle Tips
Find out high-fiber diets in fruits, vegetables, and whole grains.
Consume 8–10 liters of water per day to stay hydrated.
Take short walks to help stimulate bowel movements.
Avoid NSAIDs and limit alcohol consumption.
2. Medications
Iron supplements to correct anemia.
Stool softeners to reduce straining.
Other medications as prescribed to stop or prevent bleeding.
3. Minimally Invasive or Advanced Procedures
Endoscopic treatments such as clips or thermal coagulation during colonoscopy.
Angiographic embolization to selectively block the bleeding vessel.
Surgery is rarely required, reserved for severe or recurrent bleeding cases.

Frequently Asked Questions
Is diverticular bleeding dangerous?
In most cases, the bleeding resolves on its own. However, severe or prolonged bleeding can lead to anemia or even hemorrhagic shock. Seek medical attention immediately if heavy bleeding occurs.
Can I stop it at home?
Rest, stay hydrated, and eat light, high-fiber foods. Avoid NSAIDs. If bleeding persists or worsens, contact Dr. Scott for professional evaluation and treatment.
How do I know it’s not just hemorrhoids?
Hemorrhoids usually cause itching or pain around the anus, while diverticular bleeding is painless and occurs in the colon. It often presents as bright red or maroon blood in the stool without discomfort.
What happens during diagnosis?
Your doctor may order blood tests to check for anemia and perform a colonoscopy to locate the bleeding source. In severe cases, CT angiography may be used to detect active bleeding.
Can diet help prevent diverticular bleeding?
Yes. A diet rich in fruits, vegetables, whole grains, and adequate hydration helps maintain bowel health and reduce pressure in the colon, lowering the risk of bleeding.
When should I go to the ER?
Seek emergency care if you experience dizziness, fainting, rapid heartbeat, or low blood pressure — these may indicate significant blood loss.
Are there long-term changes after treatment?
Most patients recover fully by making simple dietary and lifestyle adjustments, along with regular check-ups to monitor colon health.
