THURSDAY, Aug. 2 HealthDay News)--new research suggests that the 1.4 million Americans have celiac disease, but do not know, while 1.6 million people are on a gluten-free diet for celiac disease--treatment--even though they may not be necessary.
The results, which estimates that 1.8 million Americans have celiac disease--autoimmune condition--indicate that the percentage of 78 patients do not always realize that they have the condition.
"This is proof that the disease is common in the United States," said co-author Dr. Joseph Murray, a gastroenterologist at the Mayo Clinic in the news release. "If you have one person to detect every five or six [who] are not very good job we're doing, celiac disease detection."
People with celiac disease have trouble sample of wheat, rye and barley. Gluten-free diet can help, but around 80% of the people on such a diet not recognized in celiac disease.
"There are many people on a gluten-free Diet and not clear what is the medical need for that," said Murray. "This important if someone thinks that they have celiac disease, that they be tested first before they go on a diet."
The researchers came to their conclusions by examining the results of tests of blood and establish a national test.
Celiac disease seems to be particularly common in the white race.
"Virtually all of the people we were non-Hispanic Caucasians," said co-author Dr. Alberto Rubio-Tapia, Mayo Clinic gastroenterologist, release news. But, he said, the results are head scratching because studies in Mexico had suggested that the disease celiac is common.
Research was partially funded by the U.S. National Institutes of Health and the Centre for disease prevention and control.
Study appears in the American Journal of Gastroenterology, July 31.
