Overview
Common risk factors in the development of lower GI bleeding include advancing age, previous history of gastrointestinal bleeding, chronic constipation, hematologic disorders, medications such as anticoagulants, non-steroidal anti-inflammatory drugs, and human immunodeficiency virus infection.
Risk Factors
Common risk factors in the development of lower GI bleeding include:[1][2][3][4]
- Advancing age
- Previous history of gastrointestinal bleed
- Chronic constipation
- Hematologic disorders
- Anticoagulants
- Non-steroidal anti-inflammatory drugs
- Human immunodeficiency virus infection
| Risk factor | Pathophysiology of bleeding |
| Chronic constipation | Results in colonic diverticula and predispose patients to anal fissures and hemorrhoid formation |
| Hematologic disorders | Deficiencies in clotting factors, such as factor VII and factor VIII, predispose to LGIB |
| Anticoagulants | Patients taking warfarin, heparin, aspirin, and platelet inhibitors are at increased risk of bleeding in general |
| Nonsteroidal anti-inflammatory drugs | NSAIDs cause ulceration in the terminal ileum and proximal colon, and can exacerbate IBD |
| Human immunodeficiency virus | In patients with HIV, bleeding is caused by opportunistic infections, cytomegalovirus colitis, Kaposi sarcoma, or lymphoma |
