If you’ve tested yourself for coeliac disease, sometimes the results can be a little confusing. Let’s go through everything for you here.
Coeliac disease is an autoimmune condition that affects around 1 in 100 people in the UK, with many people being diagnosed in their adult life. In those with coeliac disease, when they eat any foods containing gluten, the body’s immune system attacks its own tissues. This causes the guts lining to be damaged, which hinders the absorption of nutrients from food. Coeliac disease is not an allergy or food intolerance and the only treatment option is a gluten-free diet.
First of all, the tests will only work if you’ve eaten a diet containing at least 2 gluten meals a day for the past 6 weeks. Although this isn’t very nice as it’ll probably make you feel unwell, it’s the only way to make sure the antibodies show up on the tests below. If any of the tests are positive, then the next step is to see a gastroenterologist who will take a biopsy of your gut. We can’t confirm coeliac disease with blood tests alone.
Some people lack IgA antibodies and so this test can sometimes be negative. If you have symptoms, then other tests are advised.
This test looks at the genetics behind coeliac disease. Both these genetic markers are strongly associated with coeliac disease. Rarely there are some people who will have negative tests for the two tests above and these people may benefit from this test. However, these genetic markers are highly variable and present in a lot of people who don’t have coeliac disease as well. Therefore, they should only be used for symptomatic patients who have negative tests to the normal coeliac screens, and even then, the results can only be interpreted reliably by a gastroenterology expert who will want to see you for a biopsy as well. The only exception to this rule are children who may be diagnosed with coeliac disease based blood tests and HLA screens without the need for a biopsy.
Frustratingly the only treatment for coeliac disease is a gluten-free diet. There are no medications or procedures which can cure it. Once you have coeliac disease, you have it for life, so it is incredibly important to try to stick to a gluten-free diet.
Here’s some simple advice for you to get started:
A lot of gluten-free foods can be prescribed by your GP and this can really help both practically and financially. Discuss with your GP what’s available.
