Rate of Celiac Diagnosis Shows Significant Improvement in U.S.
While the number of people with celiac disease in the United States remained relatively stable from 2009 to 2014, the number of those cases going undiagnosed decreased by about half.
Researchers from the Mayo Clinic, who looked at information from National Health and Nutrition Examination Surveys, say the increase in diagnosis is likely from success in detection, an increased awareness of celiac disease or perhaps an increasing preference for a gluten-free diet.
They looked at blood test results of more than 22,000 participants over the age of six.
On that note: while rates of celiac disease remained stable, the number of people following a gluten-free diet without a celiac diagnosis more than tripled, increasing to an estimated 3.1 million people.
