Abstract

Background: Upper gastrointestinal bleeding (UGIB) remains a critical cause of emergency hospitalization globally. Despite advances in diagnostic and therapeutic strategies, UGIB continues to carry significant morbidity and mortality, influenced by etiology, comorbid conditions, and healthcare system factors. This review synthesizes current evidence on UGIB incidence, risk predictors, management strategies, and clinical outcomes.

Methods: A narrative review of contemporary literature was performed, emphasizing epidemiological trends, prognostic scoring systems, comorbidity influences, endoscopic and medical therapies, and outcome determinants. Key data sources included clinical registries, guideline recommendations, prospective cohort studies, and comparative analyses of risk stratification tools.

Results: Incidence of UGIB shows a decline over recent decades, attributed to Helicobacter pylori management and proton pump inhibitor use, while aging populations and antithrombotic medication use pose ongoing challenges [turn0search3] [turn0search14] [turn0search15]. Peptic ulcer disease and erosive lesions remain principal non‑variceal causes, with variceal bleeding significant among cirrhotic patients [turn0search20]. Risk stratification with validated tools (GBS, AIMS65, ABC, Rockall, PNED) guides clinical decisions on intervention urgency and disposition [turn0search9][turn0search8]. Comorbidities such as cardiovascular disease and chronic organ dysfunction substantially elevate mortality risk [4] [turn0search8].

Conclusion: Effective UGIB management integrates accurate early risk assessment, tailored resuscitation, timely endoscopic intervention, and longitudinal care addressing underlying disease. Emerging predictive models and evidence‑based practices aim to optimize outcomes; however, further research is needed to refine stratification tools and guideline implementation in diverse clinical settings.
