What Is Angiodysplasia?
Angiodysplasia is an issue in which tiny blood vessels leading to the lining of the colon or small intestine weaken and therefore, can easily bleed. Most chronic bleeds often result in iron deficiency and anemia in the absence of the early symptoms.
Common Causes and Risk Factors
Age over 60.
Chronic kidney disease.
Diseases of heart valves (e.g. aortic stenosis).
History — gastrointestinal bleeding.
The use of blood thinners or NSAIDs (ibuprofen, etc.).
Signs and Symptoms
Stool contains red blood — dark or bright.
Feeling tired or weak.
Painful breathing as a result of iron deficiency.
Lightheadedness or fainting.
Discomfort in the belly or stomach.
How Dr. Scott Diagnoses This Condition?
Dr. Scott uses a step-by-step approach:
Medical History and Exam
He reviews your case of GI bleeding periods, history of symptoms, medications (blood thinners/NSAIDs) and risk factors such as age, kidney disease or heart valve issues.
Blood Tests
The extent of anemia is ascertained by full blood count and iron analysis and other blood-bleeding conditions are eliminated by coagulation samples.
Imaging Studies
Colonoscopic observation of the large intestine in angiodysplasia.
Detailed examination of small bowels: Capsule endoscopy.
CT angiography to determine the locations of active bleeding and vascular mapping.
Advanced Testing (if needed)
Before intervention, mesenteric angiography or tagged red blood cell scan can be used to localise intermittent bleeding.

Frequently Asked Questions
Which is the difference between colon and small bowel angiodysplasia?
Colon angiodysplasia is a disorder that affects the large intestine, while small bowel angiodysplasia affects the small intestine. Both conditions can cause internal bleeding and may require multiple diagnostic tests.
Which symptoms should one be aware of?
Be aware of black or bright red stools, dizziness, fatigue, or breathlessness — these may indicate internal bleeding.
How long does treatment take?
Endoscopic therapies typically take less than an hour. Recovery usually takes only a few days, depending on the procedure.
Can diet stop the bleeding?
Diet alone cannot prevent bleeding, but consuming iron-rich foods and avoiding gastrointestinal irritants helps improve healing and manage anemia.
Is angiodysplasia serious?
Unmanaged angiodysplasia can lead to severe anemia and complications, but with proper medical care, it can be effectively controlled.
There is a referral to Dr. Scott?
No referral is needed. You can schedule an appointment directly at our Houston clinic.
