What Is Angiodysplasia?

Angiodysplasia refers to fragile, dilated blood vessels in the lining of the digestive tract - most often in the colon, small intestine, or stomach. These weakened vessels can rupture and bleed, leading to dark or bright red stool, fatigue, and anemia.

Common Causes and Risk Factors

  • Age : Most patients are over 60
  • Chronic illnesses : Such as heart, liver, or kidney disease
  • Bleeding disorders : Clotting problems raise bleeding risk
  • Medications : NSAIDs and blood thinners can trigger bleeding
  • Aging bowel : The colon wall weakens and vessels become more fragile over time

Signs and Symptoms

  • Blood in stool (bright red or tarry black)
  • Persistent tiredness or weakness
  • Abdominal pain or cramping
  • Shortness of breath during activity
  • Low blood pressure or dizziness if bleeding is heavy

How Dr. Rishi Diagnoses Angiodysplasia?

Dr. Rishi uses a step-by-step approach:

Medical History & Exam

He reviews your symptoms, medical history, medications (like blood thinners), and risk factors.

Blood Tests

We check for anemia, low red blood cell counts, and clotting issues.

Endoscopy or Colonoscopy

A flexible scope examines your stomach, small bowel, or colon to spot fragile, bleeding vessels.

Capsule Endoscopy

A tiny camera pill travels through the small intestine, capturing images of areas a standard scope can't reach.

Imaging Tests

  • CT Angiography pinpoints active bleeding sites in your digestive tract.
  • Mesenteric Angiography locates and assesses small vessel leaks.
  • Technetium-labeled Red Blood Cell Scan detects slow, intermittent bleeding.

Treatment

Our Houston team offers a full range of care for angiodysplasia.

1. Lifestyle and Diet Tips

  • Eat more iron-rich foods like spinach and lean meats
  • Drink plenty of water to stay hydrated
  • Avoid NSAIDs (e.g., ibuprofen) that can worsen bleeding
  • Incorporate light activities such as daily walking

2. Medications

  • Iron supplements to boost red blood cell production
  • Hormone therapy to help control bleeding episodes
  • Octreotide to slow blood flow to fragile vessels

3. Minimally Invasive or Advanced Procedures

  • Endoscopic coagulation using heat or laser to stop bleeding
  • Argon plasma coagulation with ionized gas and electricity
  • Angiographic embolization to block the bleeding vessel
  • Surgical intervention only if other methods are unsuccessful

Frequently Asked Questions

What causes angiodysplasia in the colon?

Aging weakens the lining of the colon, leading to the formation of fragile blood vessels.

Can it affect the small intestine?

Yes. Angiodysplasia can occur in the small intestine and often leads to slow, chronic bleeding and anemia.

What are signs of stomach angiodysplasia?

Black or tarry stool and pain or discomfort in the upper abdomen are common signs.

Is it dangerous?

Not usually. Most bleeding is slow. Prompt diagnosis and treatment keep it safe and manageable.

How long is the endoscopy?

The procedure typically takes about 30 to 60 minutes, and you can usually go home the same day.

Will I need surgery?

Surgery is rare and reserved for cases where less invasive treatments have not been effective.

When can I return to daily life?

Most people feel back to normal within one to two days after endoscopic treatment.

Are there side effects from iron pills?

Some patients experience an upset stomach or constipation. Dr. Chadha can adjust your dosage or recommend alternatives.

How often are follow-up visits?

Follow-up intervals vary but are generally scheduled every three to twelve months based on your individual needs.

Is this condition genetic?

No. Angiodysplasia is typically related to aging and other health factors rather than inherited genetics.
