This high bleeding risk is caused by uremic platelet dysfunction, vascular fragility, intradialytic hemodynamic instability, and widespread antithrombotic therapy. Small bowel lesions, especially angiodysplasias, constitute a significant but often overlooked source of recurrent or occult hemorrhage while conventional endoscopy frequently fails to identify these lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>Investigation of small bowel lesions in hemodialysis patients and identification of bleeding risk of this vulnerable population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Design<\/jats:title>\n                    <jats:p>Narrative review.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>English language studies in the last 25\u2009years using PubMed and Google Scholar databases up to November 2025.

Large\u2010scale epidemiological analyses identified hemodialysis as an independent risk factor for gastrointestinal hemorrhage compared to peritoneal dialysis, providing the clinical background for the increased susceptibility of these patients to small bowel\u2010specific lesions. Overall, patients have a higher risk of rebleeding tendency than controls and exhibited a high\u2010risk phenotype characterized by recurrent angiodysplasia\u2010related bleeding and elevated one\u2010year mortality rates following the first bleeding episode.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Small bowel lesions may constitute a major and underrecognized cause of gastrointestinal bleeding in hemodialysis patients. Capsule endoscopy offers the highest diagnostic yield, yet optimal treatment strategies remain undefined, and recurrent bleeding episodes are common.
