Coeliac Disease and the Gluten Free Diet: What You Need to Know
Coeliac disease is a serious autoimmune disorder that affects the small intestine. When people with coeliac disease ingest gluten, a protein found in wheat, barley, and rye, their immune system attacks the small intestine. This attack damages the villi, small finger-like projections that line the small intestine and promote nutrient absorption. Damaged villi can lead to malabsorption, meaning the body cannot properly absorb nutrients from food. Managing coeliac disease requires a lifelong commitment to a strict gluten-free diet. This article provides an overview of coeliac disease and the importance of a gluten-free diet for managing the condition.
1. What is Coeliac Disease?
Coeliac disease is not a food allergy or intolerance; it's an autoimmune condition. In individuals with coeliac disease, gluten triggers an immune response that damages the lining of the small intestine. This damage can lead to a variety of symptoms and long-term health complications if left untreated.
Autoimmune Response: The immune system mistakenly identifies gluten as a threat and attacks the villi in the small intestine.
Villi Damage: The damage to the villi reduces the surface area available for nutrient absorption, leading to malabsorption.
Genetic Predisposition: Coeliac disease has a genetic component, meaning it tends to run in families. However, having the genes associated with coeliac disease does not guarantee that a person will develop the condition.
Prevalence: Coeliac disease affects approximately 1 in 70 Australians, but it is estimated that around 80% of people with the condition remain undiagnosed. This highlights the importance of awareness and proper testing.
Understanding the nature of coeliac disease is crucial for managing it effectively. It's a lifelong condition that requires careful attention to diet and lifestyle.
2. Symptoms and Diagnosis
Coeliac disease can present with a wide range of symptoms, making diagnosis challenging. Symptoms can vary from person to person and may affect different parts of the body. It's important to note that some people with coeliac disease may have no noticeable symptoms at all, while others experience severe symptoms.
Common Symptoms
Gastrointestinal Issues: Diarrhoea, constipation, abdominal pain, bloating, gas, nausea, and vomiting are common gastrointestinal symptoms.
Malabsorption Symptoms: Weight loss, fatigue, anaemia (iron deficiency), and osteoporosis (weak bones) can occur due to malabsorption of nutrients.
Other Symptoms: Skin rashes (dermatitis herpetiformis), mouth ulcers, headaches, joint pain, nerve damage (peripheral neuropathy), and reproductive problems can also be associated with coeliac disease.
Symptoms in Children: Children may experience failure to thrive, delayed growth, irritability, and dental enamel defects.
Diagnosis
Diagnosing coeliac disease typically involves a combination of blood tests and an intestinal biopsy.
- Blood Tests: Blood tests can detect antibodies that are elevated in people with coeliac disease. The most common tests include:
Tissue Transglutaminase Antibody (tTG-IgA)
Endomysial Antibody (EMA-IgA)
Deamidated Gliadin Peptide (DGP IgA and IgG)
It's crucial to be consuming gluten regularly for at least 6 weeks before blood tests are performed, as a gluten-free diet can lead to false negative results.
- Intestinal Biopsy: If blood tests are positive, an intestinal biopsy is usually performed to confirm the diagnosis. During a biopsy, a small sample of tissue is taken from the small intestine and examined under a microscope for damage to the villi.
- Genetic Testing: Genetic testing can identify individuals who are at risk of developing coeliac disease. However, genetic testing alone cannot diagnose coeliac disease, as many people with the genes associated with the condition never develop it.
If you suspect you may have coeliac disease, it's important to consult with a doctor for proper testing and diagnosis. Early diagnosis and treatment can help prevent long-term health complications.

3. The Importance of a Strict Gluten Free Diet
The cornerstone of managing coeliac disease is a strict gluten-free diet. This means completely eliminating all sources of gluten from your diet. Even small amounts of gluten can trigger an immune response and damage the small intestine.
Healing the Intestine: A gluten-free diet allows the small intestine to heal and the villi to regenerate, improving nutrient absorption.Symptom Relief: Eliminating gluten can alleviate symptoms such as diarrhoea, abdominal pain, and fatigue.
Preventing Complications: A strict gluten-free diet can help prevent long-term health complications associated with coeliac disease, such as osteoporosis, anaemia, and certain types of cancer.
Key Considerations for a Gluten-Free Diet
Read Labels Carefully: Always read food labels carefully to check for gluten-containing ingredients. Look for products that are labelled "gluten-free."
Cross-Contamination: Be aware of cross-contamination, which can occur when gluten-free foods come into contact with gluten-containing foods. Use separate cutting boards, utensils, and toasters for gluten-free and gluten-containing foods. When eating out, inform the restaurant staff that you have coeliac disease and need to avoid gluten.
Naturally Gluten-Free Foods: Focus on naturally gluten-free foods such as fruits, vegetables, meat, poultry, fish, beans, lentils, and gluten-free grains like rice, quinoa, and corn.
Gluten-Free Alternatives: Many gluten-free alternatives are available for common gluten-containing foods, such as bread, pasta, and crackers. Glutenfreeflour offers a range of high-quality gluten-free flours and mixes to help you create delicious and nutritious meals.
4. Hidden Sources of Gluten
Gluten can be hidden in unexpected places, making it challenging to maintain a strict gluten-free diet. It's important to be aware of these hidden sources and take precautions to avoid them.
Processed Foods: Gluten can be used as a thickener, stabiliser, or flavour enhancer in processed foods such as sauces, soups, salad dressings, and condiments. Always read labels carefully and choose gluten-free options.
Medications and Supplements: Some medications and supplements may contain gluten as a binding agent. Check with your pharmacist or doctor to ensure that your medications and supplements are gluten-free.
Cosmetics and Personal Care Products: Although less likely to be ingested, some cosmetics and personal care products, such as lipsticks and lip balms, may contain gluten. Consider using gluten-free alternatives.
Communal Food Preparation: Shared cooking oils, toasters, and other kitchen equipment can easily cause cross-contamination. Ensure thorough cleaning or use separate equipment.
Examples of Hidden Gluten Sources:
Soy sauce (most varieties contain wheat)
Modified food starch (can be derived from wheat)
Malt flavouring
Brewer's yeast
Some types of liquorice
Being vigilant about hidden sources of gluten is essential for managing coeliac disease effectively. Don't hesitate to contact manufacturers or research ingredients if you're unsure whether a product contains gluten. If you have any frequently asked questions, please refer to our FAQ section.
5. Living with Coeliac Disease
Living with coeliac disease requires ongoing management and adaptation. However, with proper knowledge and support, people with coeliac disease can lead healthy and fulfilling lives.
Education and Awareness: Educate yourself about coeliac disease and the gluten-free diet. Stay informed about new research and developments in the field.
Support Groups: Join a coeliac disease support group to connect with other people who understand the challenges of living with the condition. Sharing experiences and tips can be helpful.
Registered Dietitian: Consult with a registered dietitian who specialises in coeliac disease and the gluten-free diet. A dietitian can help you develop a personalised meal plan and provide guidance on label reading, cross-contamination prevention, and nutrient deficiencies.
Regular Medical Check-ups: Schedule regular check-ups with your doctor to monitor your health and ensure that your coeliac disease is well-managed.
Advocacy: Advocate for yourself and others with coeliac disease. Raise awareness about the condition and the importance of gluten-free options in restaurants, schools, and other public places.
Living with coeliac disease can be challenging, but it's important to remember that you're not alone. With the right tools and support, you can successfully manage your condition and enjoy a healthy, gluten-free life.
