What You Should Know About Celiac Disease and Gluten

What Is Celiac Disease?

Celiac disease is an autoimmune condition. When someone with celiac disease eats gluten (found in foods like bread, pasta, cereals, and many processed foods), their immune system mistakenly attacks the lining of their small intestine.

Over time, this damages the intestinal wall, making it harder for the body to absorb nutrients from food. If left untreated, this can lead to nutritional deficiencies, growth delays, and other health complications.

For children with Down syndrome, who may already have unique growth patterns or digestive sensitivities, early detection and management of celiac disease can make a big difference.

🧬 Why Are Children With Down Syndrome at Higher Risk?

Children with Down syndrome have a higher tendency toward autoimmune conditions because of differences in how their immune systems function. Research suggests that anywhere from 5% to 10% of individuals with Down syndrome may develop celiac disease which is several times higher than the general population.

This increased risk doesn’t mean gluten should automatically be removed from your child’s diet. It does, however, mean that screening for celiac disease should be a normal part of their ongoing health check-ups.

🔎 Symptoms to Watch For

Celiac disease can look very different from one child to another. Some children have clear digestive symptoms, while others show more subtle or non-digestive signs.

Here are some common symptoms to look out for:

Digestive symptoms:

• Frequent bloating or gas
• Diarrhoea or constipation
• Abdominal pain
• Pale, bulky, or foul-smelling stools
• Vomiting

Non-digestive symptoms:

• Poor weight gain or slow growth
• Fatigue or low energy
• Irritability or changes in mood
• Dental enamel defects
• Anaemia (low iron levels) that doesn’t improve with supplements
• Delayed puberty or missed milestones

 In some children with Down syndrome, these signs might be mild or easily mistaken for other conditions, which is why regular testing is so important, even if your child seems healthy. 

When and How to Test for Celiac Disease

Because of the increased risk, most experts recommend that all children with Down syndrome be screened for celiac disease, even if they have no symptoms.

Testing usually includes:

1. A simple blood test - This test checks for certain antibodies (like tTG-IgA or EMA) that are typically elevated when celiac disease is present.

2. A follow-up biopsy (if needed) - If the blood test results are positive, your child’s doctor may refer you to a gastroenterologist for a small intestinal biopsy to confirm the diagnosis.

💡 Important note: If your child is already eating a gluten-free diet before testing, the results may be inaccurate. Always speak to your doctor before making any major dietary changes.

Screening schedule recommendations:

• At diagnosis of Down syndrome (baseline testing)
• Every 2–3 years thereafter, or sooner if symptoms appear

    🍞 What Happens After a Diagnosis?

If your child is diagnosed with celiac disease, the main treatment is a strict, lifelong gluten-free diet. This means avoiding foods that contain wheat, barley, rye, and any products made from them.

At first, this can feel overwhelming — but with time and support, most families find that managing a gluten-free diet becomes second nature.

Practical tips for getting started:

• Learn to read labels carefully — Gluten can hide in sauces, soups, snacks, and even medications.
• Work with a dietitian who understands both Down syndrome and celiac disease — they can help ensure your child gets all the nutrients they need.
• Explore gluten-free alternatives — There are now excellent options for bread, pasta, cereals, and snacks.
• Focus on naturally gluten-free foods like rice, potatoes, fruits, vegetables, meats, eggs, and dairy products.
• Communicate with caregivers and schools so everyone involved in your child’s care understands their dietary needs.

 Within a few weeks of starting a gluten-free diet, many parents notice improvements — their child may have more energy, better digestion, and improved focus and mood.

❤️ Supporting Your Child Emotionally

For children, dietary changes can feel confusing or restrictive.

Try to make the transition positive and inclusive:

• Let your child help choose new gluten-free foods or recipes.
• Keep gluten-free treats available so they never feel left out during celebrations.
• Explain, in simple terms, that these foods help their body stay strong and healthy.

 Building a routine around their diet early on helps make it second nature and just another part of their healthy lifestyle.

👩‍⚕️ Working With Your Healthcare Team

Because celiac disease can affect growth, nutrition, and overall well-being, it’s important to work closely with your child’s healthcare team.

This may include:

• Your paediatrician
• A paediatric gastroenterologist
• A registered dietitian
• Your speech or occupational therapist (to help with any feeding challenges)

Regular monitoring and communication with your child’s care team will help ensure they stay healthy, well-nourished, and thriving.

🌟 Final Thoughts

Celiac disease is more common in children with Down syndrome, but with awareness, testing, and support, it’s completely manageable.

Remember:

• Early screening helps catch celiac disease before complications arise.
• Symptoms can vary — so even subtle changes are worth discussing with your doctor.
• A gluten-free diet can help your child feel better, grow stronger, and live more comfortably.

 With the right care and information, you can help your child enjoy food, stay healthy, and continue to grow with confidence — one meal at a time.
