A new study has suggested that celiac disease is far more prevalent in the United States than previously believed.
The illness is a genetic disorder that results in gastrointestinal and other symptoms caused by sensitivity to gluten found in wheat, rye, or barley products. Studies have shown that about 1 in 250 people in Europe has the condition, but it was thought to affect fewer individuals, about 1 in 5000, in the United States.
After screening 1200 children and adolescents aged 6 months to 20 years with serologic tests and, in some cases, small intestine biopsy, researchers reported that the prevalence of celiac disease in these patients ranged between 1 in 57 and 1 in 33. "The condition is not rare in the United States and is as common as in Europe," said Ivor Hill, MD, lead author of the study and a pediatric gastroenterologist at Wake Forest University School of Medicine.
