- There are about 2 billion cases of diarrheal disease worldwide every year. (World Gastroenterology Organisation 2012)
- Chronic diarrhea is usually related to other digestive disorders such as inflammatory bowel disease (IBD) or irritable bowel syndrome (IBS). Diarrhea can also be a symptom of intestinal infection, celiac disease or lactose intolerance.
- In the Western population, the estimated prevalence of chronic diarrhea is 4 to 5%. (Arasaradnam et al. 2018)
- Acute diarrhea is the second most common reason travellers returning from developing countries seek medical attention. (Hatchette et al. 2011)
- The incidence of travellers’ diarrhea ranges from 20 to 90% among those travelling up to two weeks in high risk regions (low and middle income countries). (The Committee to Advise on Tropical Medicine and Travel 2015)
- A 2017 study in the US demonstrated that on average, each patient with IBS with diarrhea spent US$2,268 more per year, of which 78% were from medical costs and 22% were from prescription costs. (Buono et al. 2017)
- In 2008, Canadians spent $50 million on diarrheal remedies. (Fedorak et al. 2012)
