Coeliac disease is a common autoimmune condition that affects many Australians, yet it remains widely underdiagnosed. Unlike a food intolerance, coeliac disease involves an immune reaction to gluten — a protein found in wheat, rye and barley — which causes damage to the lining of the small intestine. Without diagnosis and treatment, this damage can lead to ongoing symptoms, nutrient deficiencies and long-term health complications.
Understanding how coeliac disease is diagnosed and managed is essential for protecting gut health and overall wellbeing.
What Is Coeliac Disease?
In people with coeliac disease, gluten triggers an immune response that damages the villi of the small intestine. These villi are responsible for absorbing nutrients from food. When they are damaged, the body struggles to absorb essential vitamins and minerals, even when dietary intake is adequate.
Symptoms vary significantly and may include bloating, diarrhoea, abdominal pain, fatigue, iron deficiency, weight loss, or neurological and skin symptoms. Some people experience few or no digestive symptoms, which is why coeliac disease can go undetected for years.
How Coeliac Disease Is Diagnosed
Accurate diagnosis is critical and must be made before starting a gluten-free diet. Removing gluten too early can interfere with test results and delay confirmation.
At The Centre for Gastrointestinal Health, diagnosis follows a structured and evidence-based process.
Clinical Assessment
Your specialist will take a detailed medical history, review symptoms, assess family risk factors and determine whether further testing is required.
Blood Tests
Initial testing usually involves blood tests that look for specific antibodies associated with coeliac disease. These tests are most accurate when gluten is still being consumed regularly.
Gastroscopy and Biopsy
If blood tests suggest coeliac disease, a gastroscopy with small bowel biopsy is typically recommended. This is the gold standard for diagnosis and allows direct assessment of intestinal damage.
Our team supports patients through each step, ensuring the process is clear, thorough and well coordinated.
Managing Coeliac Disease: The Gluten-Free Diet
There is currently no cure for coeliac disease. The only effective treatment is a strict, lifelong gluten-free diet. Even small amounts of gluten can cause intestinal damage, sometimes without obvious symptoms.
What This Involves
- Avoiding all foods containing wheat, rye and barley
- Reading ingredient labels carefully
- Being aware of hidden gluten in sauces, soups and processed foods
- Preventing cross-contamination at home and when dining out
Naturally gluten-free foods include fresh fruit and vegetables, meat, fish, eggs, legumes, dairy, rice and other gluten-free grains. Packaged foods labelled gluten-free can also be safely included when selected carefully.
Practical Tips for Living Gluten-Free
Adjusting to a gluten-free lifestyle can be challenging, particularly early on. These strategies can help support long-term success:
Educate yourself
Understanding where gluten is commonly found, including less obvious sources, is essential to avoiding accidental exposure.
Plan meals ahead
Preparing meals and snacks in advance reduces reliance on convenience foods and lowers the risk of gluten intake.
Seek professional guidance
Working with experienced Accredited Practising Dietitian’s (APD) helps ensure nutritional needs are met and deficiencies are avoided.
Be mindful when eating out
Clear communication with venues and awareness of food preparation practices are key to maintaining a safe gluten-free diet outside the home.
Allow time for healing
While symptoms may improve quickly, intestinal healing can take longer. Ongoing follow-up is important to monitor recovery.
Why a Confirmed Diagnosis Matters
Self-diagnosing or starting a gluten-free diet without proper testing can complicate future diagnosis and mask other underlying conditions. A confirmed diagnosis allows for appropriate monitoring, nutritional assessment and screening for associated issues such as iron deficiency and bone health concerns.
It also provides clarity, reassurance and a clear management plan.
