WASHINGTON — People who think they are sensitive to gluten haven’t been properly tested for celiac disease, according to a new study at the Eastern Health Clinical School at Monash University and Alfred Hospital in Melbourne, Australia.

Celiac disease is a condition where eating gluten – a protein found in grains like rye and wheat – damages the lining of the intestines and leads to digestive complications like diarrhea and cramping.

In other cases, celiac disease could lead to anemia and neurological disorders, says Claire LeBrun, a senior nutritionist at the George Washington University Medical Faculty Associates.

If you have a gluten sensitivity, it’s important to get tested for celiac disease, Lebrun says. Those with celiac disease have to be “vigilant” to avoid gluten altogether.
