The standardized mortality ratio for inflammatory bowel disease (IBD) ranges from approximately 1.4 times the general population (Sweden) to 5 times the general population (Spain). Most of this increase appears to be in the Crohn disease population; the ulcerative colitis population appears to have the same mortality rate as the general population. [38]

The majority of studies indicate a small but significant increase in mortality associated with IBD. [39] A frequent cause of death in persons with IBD is the primary disease [40] ; infections and COPD/respiratory illness are other major causes of death. [41] IBD is not a risk factor for cardiovascular mortality. [42]
