Diagnosis & Treatment



celiac disease diagnosis videoAccurately diagnosing celiac disease can be quite difficult largely because the symptoms often mimic those of other diseases, including irritable bowel syndrome (IBS), Crohn's disease, intestinal infections, lactose intolerance and depression.

Blood tests are the first step in a diagnosis of celiac disease. A doctor will order one or more of a series of blood tests to measure your body's response to gluten.

Currently, recommended tests include: 

  • Total IgA
  • IgA-tTG
  • IgA-EMA
  • If IgA is deficient, it is recommended that the IgG/IgA-DGP also be ordered. At the discretion of the doctor, IgG-AGA can also be ordered.

**It is important to continue eating a normal, gluten-containing diet before being tested for celiac. If the blood tests and symptoms indicate celiac, a physician may suggest a biopsy of the lining of the small intestine to confirm the diagnosis.

celiac disease video - gluten-free dietThe only treatment for celiac disease is a lifelong gluten-free diet.  Eating gluten, no matter how small the amount, can damage the intestine.

A gluten-free diet means avoiding all foods that contain wheat (including spelt, triticale and khorasan), rye, and barley.

Despite these restrictions, people with celiac disease can eat a well-balanced diet with a variety of foods, including bread and pasta. Many gluten-free products are now made with potato, rice, soy, or bean flour. In addition, plains meat, fish, fruits and vegetables do not contain gluten, so celiacs can eat as much of these foods as they like. Learn more in NFCA's Printable Guides section.
