Angiodysplasia is a condition in which fragile, dilated blood vessels form in the lining of your digestive tract-most commonly in the right (ascending) colon, small intestine, or stomach. These weakened vessels can rupture and bleed, leading to iron-deficiency anemia or visible blood in the stool. In some cases, angiodysplasia is associated with heart valve disorders such as aortic stenosis (Heyde's syndrome).
Early on, you may have no symptoms. When bleeding occurs, you might experience:
The exact cause of angiodysplasia often remains unclear, but several factors can contribute:

Angiodysplasia most commonly occurs in the right side of the colon (ascending colon), but it can also appear in the small intestine or stomach.
Small bowel angiodysplasia is typically detected using capsule endoscopy or specialized endoscopic scopes that visualize the small intestine.
Yes. While bleeding may be slow and chronic, angiodysplasia can lead to significant blood loss and anemia over time.
Yes. Angiodysplasia is often linked with aortic stenosis (Heyde's syndrome), where a heart valve issue contributes to bleeding in the gut.
During endoscopy, angiodysplasia appears as small, flat or slightly raised red spots or patches that bleed easily when touched.
Iron supplements can help correct anemia caused by chronic bleeding but do not address the underlying vascular lesions.
Most endoscopic treatments-such as argon plasma coagulation or laser therapy-are minimally invasive, well-tolerated, and require little to no recovery time.
The most commonly used ICD-10 codes are K31.82 (angiodysplasia of stomach and duodenum) and K63.5 (angiodysplasia of intestine); your physician will select the appropriate code.
Yes. Regular follow-up endoscopies every 6-12 months-or sooner if bleeding recurs-are recommended to monitor and manage any new lesions.
Recurrence is possible. Ongoing surveillance and prompt treatment of new bleeding sites help prevent complications and maintain iron levels.
