BACKGROUND: Little is known regarding the dietary behaviors and epidemiology of irritable bowel syndrome (IBS) patients in the USA. METHODS: This was an IRB-approved cross-sectional survey conducted via a secured online server (SurveyMonkey®). A representative sample of the US population was queried regarding demographics, gastrointestinal (GI) symptoms, treatments and dietary practices. Of 1718 respondents, 161 reported IBS. These were compared to 1116 subjects reporting no GI diagnosis (controls). RESULTS: Overall, 9% reported a diagnosis of IBS. When compared to controls, IBS patients were more likely over 45 years (P<0.001) and female (P<0.001). IBS patients more frequently noted abdominal pain, constipation, diarrhea, gas/bloating and GERD/heartburn (all P<0.001) than controls. Regarding therapeutic measures, IBS patients were more likely to cite food avoidance, over-the-counter remedies, probiotics, consultation with doctor/dietitian, and prescriptions (all P<0.001). However, they were less likely to believe their strategies were effective. While the majority of subjects believed food contributed to their symptoms, those with IBS listed more dietary triggers. IBS patients were more likely to follow a dietary 'plan' with 21% citing lactose-free, 17% gluten-free and 9% low-FODMAP (all P<0.001). Nevertheless, 47% with IBS denied following any dietary plans. A minority, (24%), of IBS patients was aware of the low-FODMAP diet. CONCLUSIONS: In this US survey, IBS was reported by 9% of the population, most often females over 45 years. IBS patients were more likely to implement therapeutic strategies and cite food triggers, yet few were aware of the low-FODMAP diet. Outreach programs could improve awareness of this substantiated intervention.
