Angioectasias (also called angiodysplasias) are small, fragile blood vessels that form in the lining of the digestive tract. They most commonly develop in the colon but can appear in the stomach or small intestine. Because these vessels are weak, they may leak blood slowly over time, leading to anemia or visible bleeding.
Many people with angioectasias have no symptoms until bleeding begins. When symptoms do appear, they may include:
Angioectasias develop for reasons that aren't fully understood, but several factors increase your risk:

Angioectasia (also called angiodysplasia) is a small, weakened blood vessel in the gastrointestinal tract-most often the stomach or colon-that can rupture and cause bleeding.
Yes. Chronic, slow bleeding from angioectasias can lead to iron deficiency and anemia, resulting in fatigue, weakness, or dizziness.
Angioectasias are typically detected via endoscopy or colonoscopy. Capsule endoscopy can help locate lesions deeper in the small intestine, and CT scans may be used if needed.
No. Dieulafoy lesions involve a single, large abnormally dilated artery, whereas angioectasias consist of multiple small, fragile vessels.
Yes. Even after successful treatment, angioectasias can recur, which is why regular follow-up and monitoring are important.
Most angioectasias are treated during endoscopy using heat (thermal coagulation), laser therapy, or injection therapy, avoiding the need for surgery in the majority of cases.
While many cases are mild, untreated bleeding can lead to significant blood loss, anemia, and related symptoms. Early detection and treatment minimize risks.
Yes. Although less common than in the stomach or colon, angioectasias can develop anywhere along the gastrointestinal tract, including the esophagus.
Signs may include bright red or dark (tarry) stools and symptoms of anemia such as fatigue and shortness of breath. Only diagnostic tests like endoscopy can confirm their presence.
If you notice any bleeding in your stool, unexplained fatigue, dizziness, or signs of anemia, you should schedule an evaluation with a gastroenterologist promptly.
