Coeliac Disease in Children: Understanding Gluten Allergy in Infants and Support in London

Could your child unknowingly be affected by a hidden autoimmune condition? Coeliac disease remains misunderstood despite affecting 1 in 100 children in the UK. Recognising symptoms early can dramatically improve long-term health outcomes, yet confusion between coeliac disease and gluten allergy persists. 

We understand your worries and offer valuable insights and support resources, specifically tailored for managing coeliac disease in children.

What is Coeliac Disease?

Coeliac disease is an autoimmune disorder triggered by gluten, a protein found in wheat, barley, and rye. According to the NHS, when children with coeliac disease consume gluten, their immune system attacks the lining of the small intestine. This immune response damages villi, tiny finger-like projections vital for nutrient absorption, and can severely impact a child’s growth and wellbeing.

Symptoms of Coeliac Disease in Children

Identifying coeliac disease can be challenging due to its varied manifestations. Common symptoms include:

• Digestive issues: Chronic diarrhoea, constipation, abdominal bloating, and pain

• Growth problems: Poor weight gain, delayed growth, or failure to thrive

• Fatigue: Ongoing tiredness due to inadequate nutrient absorption

• Behavioural changes: Irritability or anxiety linked to chronic discomfort

Understanding Gluten Allergy in Infants

Unlike coeliac disease, a gluten allergy (more precisely, an IgE-mediated wheat allergy) in infants results in immediate immune reactions after consuming gluten-containing foods. Symptoms include:

• Skin reactions like hives or rashes

• Facial swelling

• Breathing difficulties or nasal congestion

Specialists may recommend an oral food challenge to confirm gluten or wheat-related allergies under controlled clinical supervision. These symptoms do not cause long-term intestinal damage but require immediate management. The American College of Allergy, Asthma & Immunology (ACAAI) provides helpful information on wheat allergy in children. 

Diagnosing Coeliac Disease in Children

Accurate diagnosis is crucial and usually involves a combination of the following, widely available across London:

• Detailed clinical History

• Blood tests: To identify specific antibodies related to coeliac disease

• Endoscopy and biopsy: To visually confirm intestinal damage

• Genetic testing: To detect predisposition in inconclusive cases

Specialist clinics like London Allergy Consultants offer full diagnostic pathways tailored for paediatric patients. Families can start by booking comprehensive food allergy testing in London, which includes screening for coeliac-related markers. Where needed, we will refer them for GI biopsies.

Managing Coeliac Disease in Children

Managing coeliac disease means committing to a strict gluten-free diet for life. Effective strategies include:

• Dietary education: Helping families learn how to read labels and avoid hidden gluten, with guidance from Coeliac UK.

• Nutritional support: Collaborating with paediatric dietitians to ensure balanced nutrition. We closely moitor growth and elements such as Iron stores and Full Blood Count.

• Monitoring and follow-up: Regular check-ups to track symptoms and nutrient levels.

Support from a qualified paediatric allergy specialist in London ensures children receive the right care and guidance. In some cases, oral food and drug challenges are used to rule out other allergens that might complicate a coeliac diagnosis or present alongside it.

Frequently Asked Questions

• Can infants have coeliac disease?

  Yes, it can develop once gluten is introduced, typically around four to six months of age.

• What's the difference between gluten allergy and coeliac disease?

  A gluten (wheat) allergy causes immediate reactions, and IgE allergy tests will be positive. In contrast, coeliac disease causes long-term gut (and other) symptoms, and specific IgG and IgA antibodies will be positive if gluten is eaten at the time of testing.

• How common is coeliac disease in children?

  Approximately 1 in 100 children in the UK are affected, although many remain undiagnosed (NHS).

• Is coeliac disease hereditary?

  Yes, it runs in families. Testing is advised for first-degree relatives. Negative HLA Gene testing can be very reassuring as the disease is unlikely. Positive testing will require a more detailed assessment to see if the disease is present.

• Is there a cure for coeliac disease?

  There’s no cure, but symptoms and damage can be managed by maintaining a gluten-free diet.
