Celiac disease is a debilitating genetic disorder that affects 1 in 133 Americans, according to a July 2, 2010 article on Celiac.com. Many people may be suffering from celiac disease with no idea what is causing their disruptive symptoms.
Niddk.nih.gov reported that in a sample of people with a child, parent or sibling who has celiac disease, the ratio jumps to 1 in 22 people being afflicted with the disorder.
There seems to be a genetic component affecting who may have celiac disease. Celiac.com stated that Europeans, Northern Europeans in particular, as well as Asian, Black and Hispanic people are at higher risk for celiac than other peoples.
Eating wheat, rye and barley can cause classic celiac symptoms such as diarrhea, malnutrition and weight loss as well as weakness, bone pain and abdominal bloating. Oats may also be bad for some celiac sufferers. It's the gluten in these grains that wreaks havoc.
