Natural History

• Small bowel angiodysplasia (SBA) contributes to 50% of obscure GI bleeding.
• SBA tends to re-bleed more than angiodysplasia of the colon and stomach.
• In a retrospective study, re-bleeding occurred after about 11 months of diagnosis in 80% of patients, and 3.5% died as a direct result of bleeding.
• Multiple lesions and valvular heart diseases have been found to increase the risk of re-bleeding.
• Apart from recurrence of bleeding, some other concerns in the natural history of angiodysplasia are transfusion requirements, hospital readmissions, and requirement endoscopic, pharmacological, or surgical therapy.
• In asymptomatic people, the course of angiodysplasia is benign, and the bleeding risk is low. Consequently, treatment is not required for incidentally found lesions.

Complications

• Anemia
• Death from excessive blood loss
• Side effects from treatment
• Severe loss of blood from the GI tract

Prognosis

Patients who have bleeding related to this condition despite having had a colonoscopy, angiography, or surgery are likely to have more bleeding in the future. The outlook remains good if the bleeding is controlled.
