What is Food Allergy Management in Children?

Food allergy in children is an immune-mediated adverse reaction to specific food proteins, distinct from food intolerance which lacks immune mechanism.

IgE-mediated reactions are immediate (minutes to 2 hours): urticaria, angioedema, vomiting, wheezing or anaphylaxis. Non-IgE mediated reactions (FPIES, FPIAP, eosinophilic gastroenteropathy) are delayed and chronic.

The most common food allergens in children are cow's milk, hen's egg, peanut, tree nuts, wheat, soy, fish and shellfish — together accounting for 90% of paediatric food allergies.

Diagnosis is based on detailed history, skin prick tests, specific IgE measurements and oral food challenge as gold standard. Component-resolved diagnostics improve specificity (e.g., Ara h 2 for peanut).

Symptoms

Acute urticaria, angioedema (lip, eye and tongue swelling)
Vomiting, abdominal pain, diarrhoea (with or without blood)
Wheezing, cough, throat tightness, dyspnoea
Anaphylaxis: hypotension, syncope, multi-system involvement
Atopic dermatitis flare after exposure
Failure to thrive, chronic diarrhoea (non-IgE mediated)
Eosinophilic oesophagitis: dysphagia, food impaction, vomiting

Risk Factors

Family history of atopy (asthma, allergic rhinitis, atopic dermatitis)
Atopic dermatitis in infancy (especially severe)
Delayed introduction of allergenic foods (now disproven — early introduction recommended)
Vitamin D deficiency, low fibre diet, microbiome disturbance
Caesarean delivery and lack of breastfeeding
Filaggrin gene mutations (skin barrier defect)
High-risk peanut allergy: severe eczema or egg allergy infants

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Any reaction to food in infancy or childhood requires allergist evaluation
  • Generalised urticaria, angioedema or wheezing after food — immediate medical assessment
  • Anaphylaxis (hypotension, severe respiratory distress) — call 112 and use adrenaline auto-injector
  • Persistent eczema, recurrent vomiting or growth failure may indicate non-IgE allergy
  • High-risk infants (severe eczema) should have peanut introduction at 4–6 months under guidance

Treatment Methods

01
Strict avoidance of identified allergens with thorough food label reading and education
02
Adrenaline auto-injector (EpiPen, Jext) prescription for IgE-mediated allergies — two devices
03
Personalised emergency action plan and training for family, school and caregivers
04
Antihistamines for mild reactions (urticaria, itching) — never substitute for adrenaline
05
Oral immunotherapy for peanut (Palforzia approved for ages 4–17) — desensitisation with controlled doses
06
Cow's milk allergy: extensively hydrolysed or amino-acid based formulas
07
Regular follow-up: many allergies (milk, egg, wheat, soy) resolve by school age; peanut and tree nut persist
