Celiac disease can be difficult to diagnose because it affects people differently. There are more than 200 known symptoms of celiac disease, which can appear in the digestive system or other parts of the body. Some people develop celiac disease as children, while others develop it as adults. The cause is still unknown.
Some people with celiac disease have no symptoms but still test positive on a celiac blood test. Others may have a negative blood test but a positive intestinal biopsy. However, all people with celiac disease are at risk for long-term complications, whether they have symptoms or not.
