At what age is celiac disease typically diagnosed?

Celiac disease commonly shows up in children, but it has been diagnosed in people of all ages, mainly because not everyone with celiac disease experiences symptoms right away. (In many cases of undiagnosed celiac disease, there are no symptoms at all.) Celiac disease often occurs in those with another autoimmune disorder, and it is found in 5% to 7% of people who have Type 1 diabetes.
