Original article Health-related quality of life, work productivity and health care resource use associated with constipation predominant irritable bowel syndrome

Objectives: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder. Prevalence estimates of IBS vary widely, from 10 to 15%, in the U.S. However, few studies have examined constipation predominant IBS (IBS-C), a subtype of IBS. The aim of this study was to assess the effect of IBS-C on health-related quality of life (HRQOL), work productivity and activity impairment, and health care resource use.
