Bloating, bowel changes or unexplained tiredness can leave you wondering whether food is the problem. Before cutting out gluten, make time to discuss your symptoms with your GP.
Coeliac disease is an autoimmune condition in which gluten triggers damage to the small bowel. Gluten is found in wheat, rye and barley. Symptoms vary and can include diarrhoea, constipation, bloating or fatigue; some people have few obvious symptoms. Healthdirect — Coeliac disease.
Why does testing come first?
Removing gluten before assessment can make coeliac tests less accurate. If you think coeliac disease may be an issue, speak with your doctor before changing your diet. If you already avoid gluten, tell them so they can plan an appropriate assessment. Healthdirect — Coeliac disease.
Do not attempt a food challenge from an online article. Ask your clinician what the next step involves.
What should you bring?
Write down your symptoms, when they began and any family history of coeliac disease. Include foods you have removed, previous investigations and medicine or supplement names.
Your doctor can decide which tests are appropriate and whether a specialist referral is needed. Concerns about a child's growth or ongoing digestive symptoms also belong with their doctor. Healthdirect — Coeliac disease.
After a diagnosis
Coeliac disease requires a lifelong gluten-free diet, with medical follow-up and support from a dietitian familiar with the condition. A dietitian can help with labels, nutritional adequacy and practical food choices. Healthdirect — Coeliac disease.
Oats need a separate conversation: some people with coeliac disease react to their avenin protein, and contamination can occur. Australian gluten-free labelling excludes oats. Follow individual advice rather than relying on overseas “gluten-free oats” claims. Healthdirect — Coeliac disease.
Take one question at a time
Ask for written information and choose one practical issue to discuss first, such as shopping or eating away from home.
