Diagnosis of Celiac Disease
by Rick Alan
Your doctor will ask about your symptoms and medical history and perform a physical exam. Because the symptoms of celiac disease are often very similar to those of other conditions, it can be difficult to obtain an accurate diagnosis early on. However, early diagnosis of celiac disease is very important because the earlier you start the gluten-free diet, the less likely you are to have advanced damage to your intestinal tract. Maintaining a gluten-free diet is very important to help prevent complications caused by celiac disease.
Your doctor may suspect celiac disease:
If celiac disease is suspected, tests will be done to confirm the diagnosis. Tests include:
Blood Tests —a blood sample is taken to check for:
Endoscopy —a thin, lighted tube inserted down the throat to examine and biopsy the intestine
Biopsy —Performed via an endoscope to confirm the diagnosis of celiac disease. It requires the removal of a small sample of tissue from the small intestine during endoscopy to test for flattened and damaged villi. If the biopsy shows signs of celiac sprue, you may be put on a gluten-free diet for about 3-6 months. After that time, a second biopsy may be done to look for signs of improvement, such as positive changes in the villi of the small intestine.
