    Abstract:
    BACKGROUND: Celiac disease and functional intestinal disorders may overlap, yet the natural history of functional symptoms in patients with celiac disease is unknown. AIM: To investigate the prevalence of irritable bowel syndrome (IBS), functional dyspepsia (FD), and functional bloating (FB) symptoms among patients with celiac disease at diagnosis and during the first year of a gluten-free diet. METHODS: Adults with a new diagnosis of celiac disease were surveyed at baseline, 6 months and 1 year using standardized measures for intestinal symptoms [Rome III diagnostic questionnaire and celiac symptom index (CSI)] and gluten-free diet adherence [gluten-free eating assessment tool (GF-EAT) and celiac diet adherence test]. RESULTS: At diagnosis, two-thirds fulfilled Rome III diagnostic questionnaire symptom criteria for IBS (52%), functional dyspepsia (27%), and/or functional bloating (9%). One year post-diagnosis, there was high adherence to a gluten-free diet as 93% reported gluten exposure less than once per month on the GF-EAT and only 8% had ongoing celiac disease symptoms (CSI score >45). The rates of those meeting IBS (22%) and functional dyspepsia (8%) symptom criteria both decreased significantly on a gluten-free diet. The prevalence of functional symptoms (any of IBS, FD or FB) at 1 year was 47%. CONCLUSIONS: Long-term follow-up of patients with celiac disease is necessary because many patients with celiac disease who are adherent to a gluten-free diet have persistent gastrointestinal symptoms.
