Celiac Disease

Also called: Celiac sprue, Gluten-sensitive enteropathy, Nontropical sprue


What is celiac disease?

Celiac disease is a chronic (long-term) digestive and immune disorder that damages your small intestine. The damage may prevent your body from absorbing vitamins, minerals, and other nutrients from the food you eat. This can lead to malnutrition and other serious health problems

Celiac disease is triggered by eating foods that contain gluten. Gluten is a protein found in wheat, barley, rye, and other grains. It may also be in other products like vitamins and supplements, hair and skin products, toothpastes, and lip balm.

Celiac disease is different from gluten sensitivity and wheat allergies. Some of the symptoms may be similar, but those conditions don't damage the small intestine.

What causes celiac disease?

The exact cause of celiac disease is not known. Research suggests that celiac disease only happens in people who have certain genes and eat food that contains gluten. Researchers are studying other factors that may play a role in causing the disease.

Who is more likely to develop celiac disease?

Celiac disease is more common if you:

What are the symptoms of celiac disease?

What other problems can celiac disease cause?

How is celiac disease diagnosed?

If you have symptoms of celiac disease, your health care provider will look for signs that you might have celiac disease. To do this, your provider will get your medical and family history and do a physical exam.

If your provider thinks that you could have celiac disease, you will have some tests. Providers most often use blood tests and biopsies of the small intestine to diagnose celiac disease. The biopsy would be done during an upper gastrointestinal (GI) endoscopy. For this procedure, your provider uses an endoscope (a flexible tube with a camera) to see the lining of your esophagus, stomach, and small intestine. It also allows your provider to take a sample of tissue for a biopsy.

What are the treatments for celiac disease?

The treatment for celiac disease is following a gluten-free diet for the rest of your life. Sticking with a gluten-free diet will treat or prevent many of the symptoms and other health problems caused by celiac disease. In most cases, it can also heal damage in the small intestine and prevent more damage.

Your provider may refer you to a registered dietician (a nutrition expert) who can help you learn how to eat a healthy diet without gluten. You will also need to avoid all hidden sources of gluten, such as certain supplements, cosmetics, toothpaste, etc. Reading product labels can sometimes help you avoid gluten. If a label doesn't tell you what is in a product, check with the company that makes the product for an ingredients list. Don't just assume that a product is gluten-free if it doesn't mention it.
