A biopsy is done in hospital, usually by a gastroenterologist. A biopsy can help confirm a diagnosis of coeliac disease.There's no cure for coeliac disease, but following a gluten-free diet should help control symptoms and prevent the long-term complications of the condition. Coeliac disease is managed by following a gluten free diet. This includes avoiding foods and drinks that contain wheat, gluten, barley, rye and oats. Not everyone with coeliac disease is sensitive to oats, however it is very common.

If you have symptoms of coeliac disease, or if you're at higher risk of developing it, you should see your GP First-degree relatives (parents, brothers, sisters and children) of people with coeliac disease are also at increased risk of developing the condition. Diagnosing coeliac disease Untreated, coeliac disease can lead to long-term complications, including weakening of the bones (osteoporosis), certain kinds of anaemia, and an increased risk of bowel cancer. You should follow a gluten-free diet even if your symptoms are mild to reduce your risk of these complications.If you get a negative test result for coeliac disease and other causes of your symptoms have been ruled out, you might wish to discuss the possibility of non coeliac gluten sensitivity with your healthcare team. If coeliac disease antibodies are found in your blood, the GP will refer you to a doctor who specialises in stomach and bowel conditions (gastroenterologist). The specialist may arrange more blood tests, or a biopsy of your intestine. Non coeliac gluten sensitivity is a condition that is being recognised as a problem in many countries across the world. This is a new area and we need more research to understand the condition and who is at risk. There are no specific diagnostic tests for non coeliac gluten sensitivity.

Some researchers define non coeliac gluten sensitivity as an improvement in symptoms when following agluten free diet. However, it is difficult to rule out the possibility of aplacebo effect.Food intolerances can take some time to diagnose. Although not life threatening, food intolerance can and often does, make the sufferer feel extremely unwell and can have a major impact on working and social life. A food intolerance is caused by your body not being able to digest a certain food or an ingredient in food. There is no specific test for gluten intolerance. You might get diagnosed with gluten intolerance if you are tested for coeliac disease and get a negative result. This means coeliac disease is ruled out. So, when you test negative for coeliac disease, your symptoms may be because of something else. There are many different types of food intolerances which more commonly affect people than a food allergy. It is important to understand that not all reactions to food are because of a food allergy. Common types of food intolerances include reacting to lactose, gluten, food additives and chemicals. Histamine intolerance Gluten intolerance is when your body reacts badly to gluten. It is also called non-coeliac gluten sensitivity. Gluten intolerance symptoms are similar to those of irritable bowel syndrome (IBS) and coeliac disease. If you have gluten intolerance, you may have gastrointestinal symptoms such as:

a special diet where you avoid eating the food you might be intolerant to, to see if your symptoms get better – after a few weeks you start eating the food again to see if your symptoms return Many people feel overwhelmed when they're first diagnosed with coeliac disease. Switching to a gluten-free diet can be confusing, particularly if you've been eating foods that contain gluten for many years. Presently there are no tests for gluten intolerance and diagnosis is made by excluding coeliac disease and wheat allergy and using wheat elimination to see if symptoms resolve followed by wheat reintroduction to determine if symptoms reappear. Patients should be referred to a specialist dietitian who can guide them through the appropriate dietary regimen. Video capsule endoscopy (VCE): VCE has a sensitivity of 89% and specificity of 95% for celiac diagnosis. This method of testing is more sensitive at detecting macroscopic atrophies in comparison with regular upper endoscopy (92% vs. 55%). VCE is also useful in detecting complications linked with celiac disease. Unfortunately tests are unhelpful for this type of reaction so diagnosis is made using a combination of symptoms history and a trial of exclusion and reintroduction.

Nutrients. 2017;9(11):1268. doi:10.3390/nu9111268 We consulted Dr Adam Fox, an allergy specialist from Guy’s and St Thomas’ hospital, on whether any of these tests were useful and worth doing. Home tests for coeliac disease Children with coeliac disease may not grow at the expected rate and may have delayed puberty. Treatment for coeliac disease There's no specific test for gluten intolerance. Your GP may recommend recording what you eat and the symptoms you experience, or cutting out gluten for a specified period of time and seeing if your symptoms improve.
