Celiac Disease in Children

It needs two things: certain inherited genes (HLA-DQ2 or HLA-DQ8) and exposure to gluten. Many people carry these genes and never develop celiac disease, so the genes alone do not decide it. Nothing a parent did, such as when gluten was introduced, is known to be the cause. It can appear at any age after gluten is eaten, including toddlerhood and school age.

Celiac disease is one of the more common long-term conditions in childhood. Studies from several countries, including Saudi Arabia and the Gulf, suggest that it is more common than once thought, and that many cases go undiagnosed. We do not quote a single national figure here. It is more common in children with type 1 diabetes, autoimmune thyroid disease, Down syndrome, Turner syndrome, Williams syndrome, or selective IgA deficiency, and in close relatives of someone with celiac disease.

Wheat-based foods such as bread, samoon, freekeh, harees, jareesh, kunafa and many sweets are central to Gulf meals and gatherings, so family and school support is especially important. Gluten-free products and trained dietitians are more available in larger cities. Ask your hospital or clinic about dietitian and support services, and what your insurance covers.

IMPORTANT: Do not start a gluten-free diet before testing. Stopping gluten first can make the tests look normal and delay a correct diagnosis. Your child must still be eating gluten normally.

The usual first step is a blood test, tissue transglutaminase IgA antibody (tTG-IgA), with a check of total IgA (some children cannot make IgA, and need different tests). Based on international (ESPGHAN) guidance, a small number of children whose antibody level is very high (about 10 times the upper limit of normal), whose other antibody (anti-endomysial) test is positive on a second blood sample, and whose family agrees, may be diagnosed without a biopsy. Otherwise, the diagnosis is confirmed by upper endoscopy (a camera passed through the mouth, under anaesthesia or sedation) with small samples (biopsies) taken from the first part of the small intestine.

Genetic (HLA) testing is only used in selected situations, for example when the diagnosis is unclear. Your doctor will also usually check blood count, iron, vitamin levels, thyroid and liver tests.

Treating celiac disease is a family effort. Everyone around the child needs to understand that small amounts of gluten can matter.

• Meet a dietitian experienced in celiac disease soon after diagnosis, and review the diet regularly as your child grows.

• Prevent cross-contamination at home: separate toaster, clean surfaces and utensils, and cook the child's food first or separately.

• Tell school staff, the canteen, relatives and carers about the diet; send a safe packed lunch and snacks for parties and trips.

• Help your child understand and own the diet in an age-appropriate way, without blame or fear. Teens may need extra support, as they are more likely to slip.

• Offer testing to brothers, sisters and parents, who are at higher risk; discuss with your doctor when and how.

• Keep up routine vaccinations and regular check-ups.

The treatment is to remove gluten completely, for life. It is not a "reduce gluten" diet.

• Avoid wheat (including durum, semolina, couscous), barley, rye and foods made from them, such as ordinary bread, pasta, biscuits, cakes, and many cereals and sauces. See also our gluten-free diet article for Saudi foods.

• Many foods are naturally gluten-free: rice, corn, potatoes, plain meat, fish, eggs, milk and dairy, fruits, vegetables and legumes.

• Oats are only suitable if labelled gluten-free (ordinary oats are often contaminated), and a few children still react to them. Ask your team before introducing them.

• Read labels every time, because recipes change. Choose products labelled gluten-free where possible.

• Do not give a growing child an overly restricted diet: make sure there is enough energy, fibre, iron, calcium and vitamin D, using fortified or naturally rich foods. Do not use unproven "gluten detox" products.

There is no medicine that treats celiac disease itself; diet is the treatment. Supplements may be used to correct shortages.

• Iron, vitamin D, calcium, B12, folate or other supplements are given only if blood tests show a need, and their dose is chosen by your doctor.

• Check that any medicine or vitamin your child takes is gluten-free; ask the pharmacist.

• Immune-suppressing medicines are rarely needed, and only for unusual cases that do not respond to diet, under a specialist.

Endoscopy may be needed to confirm the diagnosis in many children.

• Upper endoscopy with small intestine biopsies, done under anaesthesia or sedation, confirms the diagnosis when the blood-test-only route is not suitable.

• Repeat endoscopy is not routine; it is only done if symptoms or tests do not improve on the diet.

The outlook is excellent. On a strict gluten-free diet most children feel better within weeks to months, growth and weight catch up, and the intestine usually heals. Antibody levels fall over many months and are used to check progress. Without treatment, the disease can lead to poor growth, anaemia, weak bones, delayed puberty and, in adulthood, other complications, so the diet matters even if a child has few symptoms. Regular follow-up (usually yearly once things are stable) checks growth, blood tests, diet and well-being.

• Is the blood test enough, or does my child need an endoscopy and biopsy?

• Should I keep giving gluten until all tests are finished?

• Which blood tests and supplements does my child need, and how often should they be checked?

• Should my other children and I be tested?

• Can my child eat oats, and how do I handle school and parties?
