Awareness, testing lead to more celiac diagnoses, doctors say

Both the prevalence and the diagnosis rate of celiac disease are up, though millions of Americans have undiagnosed celiac disease, experts say. Gastroenterologist Dr. James Wood of Altru Health System in Grand Forks, N.D., said there likely is a genetic component to celiac disease that combines with environmental factors to trigger a gluten reaction. Celiac symptoms can be attributed to many conditions, and people should avoid self-diagnosis, says Dr. Alberto Rubio-Tapia, an assistant professor of medicine at the Mayo Clinic in Rochester, Minn. http://www.grandforksherald.com/event/article/id/242694/
