Irritable Bowel Syndrome – Epidemiology – Americas
Clarivate Epidemiology’s coverage of IBS comprises epidemiological estimates of key patient populations across 45 countries worldwide. We report the prevalence of IBS 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.
Clarivate Epidemiology’s IBS forecast will answer the following questions:
- How will demographic trends, such as population aging and improving life expectancy, affect the epidemiology of IBS over the forecast period?
All forecast data are available on the Clarivate 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 total, Clarivate Epidemiology forecasts four IBS patient populations, as follows:
- Total prevalent cases.
- Constipation-predominant prevalent cases (IBS-C).
- Diarrhea-predominant prevalent cases (IBS-D).
- Mixed prevalent cases (IBS-M or IBS-A).
Note: Coverage may vary by country.
