Estimated prevalence of non-celiac gluten sensitivity (NCGS) varies between 1% and 13% of the population, and as such may be higher than the prevalence of celiac disease. Unreported cases are likely to be at a similarly high level to celiac disease [1].

Research indicates that NCGS is probably more prevalent than celiac disease. Until now, however, there has been a lack of extensive epidemiological studies to verify estimated prevalence of this condition. Clinic data from the Center for Celiac Research, University of Maryland, showed that 6% of the 9,000 patients treated there between 2004-2010 met the criteria for NCGS and complained of corresponding symptoms, without having celiac disease or wheat allergy [2]. In a recent UK study 13% of a general population sample reported symptoms attributed to gluten [3].
