How common is celiac disease?

1:133: Average risk of celiac is 1:133 in the us. If there is a family history of celiac then the risk increases.

Somewhat: Numbers range from 1 in 100 to 1 in 1000.

Pretty common: Gluten-sensitive enteropathy (celiac disease) is much less common than gluten intolerance. Like lactose intolerance, caffeine intolerance, sorbitol intolerance (with regard to needing to restrict each respective substance), people who are gluten intolerant do better to avoid gluten-containing foods. Only about 10% of the population are gluten intolerant--an inflammatory condition of small bowel.
