DRG Epidemiology's coverage of Irritable Bowel Syndrome comprises epidemiological estimates of key patient populations across 45 countries worldwide. We report the prevalence of irritable bowel syndrome for each country as well as annualized case counts projected to the national population.

Most patient populations are forecast over a period of 20 years for the major mature pharmaceutical markets of the United States, Europe, and Japan and 10 years for the other countries covered in this report.

DRG Epidemiology's irritable bowel syndrome forecast will answer the following questions:

  • How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of irritable bowel syndrome over the forecast period?

All forecast data are available on the DRG Insights Platform in tabular format, with options to download to MS Excel. All populations are accompanied by a comprehensive description of the methods and data sources used, with hyperlinks to external sources. A summary evidence table generated as part of our systematic review of the epidemiological literature is also provided for full transparency into research and methods.

In addition to the total number of cases for each forecast year, DRG Epidemiology provides at least ten years of forecast data for the following irritable bowel syndrome subpopulations:

  • IBS prevalent cases by predominant symptom status.

Note: Coverage may vary by country.
