Epidemiology

Incidence

• The incidence of acute UGIB is approximately 50 to 100 per 100,000 individuals worldwide.
• Approximately 100,000 patients are admitted to US hospitals for therapy for UGIB.

Demographics

Age

• Patients of all age groups may develop upper gastrointestinal bleeding.
• The population with UGIB has become progressively older, with a concurrent increase in significant comorbidities that increase mortality.
• Mortality increases with older age (>60 y), in both males and females.
