Understanding Coeliac Disease

Welcome to The Digestive Health Clinic! I'm Aoife McDonald, leading Irish dietitian and digestive health expert. Today, we're diving into a topic that affects many people worldwide - coeliac disease. Understanding this condition is crucial for maintaining overall health and well-being, especially for those diagnosed with it. Let's explore what coeliac disease is, its symptoms, diagnosis, and how to manage it effectively.

‍

What is Coeliac Disease? 

Coeliac disease is a chronic autoimmune disorder where the ingestion of gluten—a protein found in wheat, barley, and rye—triggers an immune response that damages the small intestine. This damage affects the absorption of nutrients from food, leading to various health issues. It’s important to differentiate coeliac disease from non-coeliac gluten sensitivity and wheat allergy, as the management and implications differ significantly.

‍

The Science Behind Coeliac Disease

When someone with coeliac disease consumes gluten, their immune system mistakenly attacks the villi, small finger-like projections lining the small intestine. Villi are crucial for nutrient absorption. Over time, this immune response can flatten the villi, leading to malabsorption of nutrients and various health complications.

‍

What are the Symptoms of Coeliac Disease? 

Symptoms can vary widely among individuals and may include:

• Digestive issues such as diarrhoea, constipation, bloating, and abdominal pain.
• Fatigue and weakness.
• Weight loss and growth problems in children.
• Anaemia due to iron deficiency.
• Skin rashes like dermatitis herpetiformis.
• Neurological symptoms: headaches, depression, and peripheral neuropathy.

Recognising these symptoms early is vital for proper diagnosis and management.

Diagnosis of Coeliac Disease 

Diagnosing coeliac disease involves a series of tests. Blood tests like tTG-IgA, EMA, and DGP detect specific antibodies. Genetic testing for HLA-DQ2 and HLA-DQ8 genes can indicate a predisposition to the disease. The most definitive test is an endoscopy with a biopsy of the small intestine to check for villi damage. 

If you suspect you have coeliac disease, contact a healthcare professional for proper testing and diagnosis. Only a qualified medical person should perform these tests to ensure accuracy and appropriate management.

‍

Managing Coeliac Disease 

The cornerstone of managing coeliac disease is a strict, lifelong gluten-free diet. This means avoiding all products containing wheat, barley, rye, and oats (unless certified gluten-free). Safe foods include naturally gluten-free items like fruits, vegetables, meat, fish, eggs, and most dairy products. Learning to read labels and identify hidden gluten in processed foods is crucial.

Nutritional considerations are also important, as individuals with coeliac disease may be prone to deficiencies in iron, calcium, fibre, and vitamins. Supplements and fortified foods can help address these gaps.

Tips for Maintaining a Gluten-Free Lifestyle 

Maintaining a gluten-free lifestyle involves more than just dietary changes. When dining out, it's important to communicate clearly with restaurant staff about your needs to avoid cross-contamination. At home, using separate cooking utensils, toasters, and storage for gluten-free foods is essential to prevent accidental gluten ingestion. Joining coeliac disease support groups can provide emotional support and practical advice, making the transition to a gluten-free lifestyle easier.

Living with Coeliac Disease 

Living with coeliac disease involves more than just adhering to a gluten-free diet; it impacts various aspects of daily life, from social interactions to psychological well-being. When dining out, it's important to communicate clearly with restaurant staff about your needs to avoid cross-contamination. At home, using separate cooking utensils, toasters, and storage for gluten-free foods is essential to prevent accidental gluten ingestion. Joining coeliac disease support groups can provide emotional support and practical advice, making the transition to a gluten-free lifestyle easier. Here are a few of my tips on how to live well with coeliac disease:

1. Dietary Management: Sticking to a gluten-free diet is crucial, but it doesn’t mean you have to miss out on delicious foods. Explore gluten-free recipes and products. Many supermarkets now have dedicated gluten-free sections, making it easier to find suitable foods.
   
   
2. Dining Out: Eating out can be challenging but not impossible. Research restaurants in advance, ask about their gluten-free options, and inform the staff about your dietary needs to prevent cross-contamination. Many places now cater specifically to gluten-free diets, providing peace of mind and enjoyable dining experiences.
   
   
3. Social Life: Social events can be tricky to navigate. When attending gatherings, inform the host of your condition and consider bringing your own gluten-free dish to share. This ensures you have something safe to eat and helps others understand your dietary requirements.
   
   
4. Travel: Travelling with coeliac disease requires extra planning. Research your destination for gluten-free dining options, and consider packing some gluten-free snacks for the journey. Apps and online resources can also help you locate gluten-free-friendly places worldwide.
   
   
5. Mental and Emotional Well-being: Living with coeliac disease can sometimes feel isolating, especially if others around you don’t understand the condition. Connecting with support groups, either locally or online, can provide emotional support and practical advice. Sharing experiences with others who have coeliac disease can be incredibly reassuring and empowering.
   
   
6. Monitoring Health: Regular check-ins with your dietitian or healthcare provider are essential to monitor your health and nutritional status. Discuss any persistent symptoms or concerns, as these could indicate accidental gluten ingestion or other health issues.
   
   
7. Education and Advocacy: Educating yourself and those around you about coeliac disease helps in managing the condition. The more people understand the severity of gluten exposure, the better they can support you. Advocacy also plays a crucial role in promoting the availability of gluten-free options in public places and raising awareness.
