Nut Allergy in Children — Belfast
Private assessment and management of peanut and tree nut allergy in children in Belfast and Northern Ireland. Dr Mugilan Anandarajan, Consultant Paediatrician, offers allergy testing, adrenaline auto-injector prescribing, and personalised management plans.
Emergency: If your child develops throat swelling, difficulty breathing, or collapse after nut exposure — call 999 immediately and use their adrenaline auto-injector if prescribed. Do not wait.
Peanut & Tree Nut Allergy
Nut allergy is one of the most common and potentially serious food allergies in children. It encompasses both peanut allergy (peanuts are legumes) and tree nut allergy (cashew, walnut, almond, hazelnut, pistachio, Brazil nut, pecan, macadamia).
Children can be allergic to one nut or multiple nuts. Cross-reactivity between peanuts and tree nuts, and between different tree nuts, is common. Accurate allergy testing is essential to determine which nuts must be avoided.
Component-Resolved Diagnostics
Testing to specific nut proteins (e.g. Ara h 2 for peanut, Cor a 14 for hazelnut) provides more precise risk assessment than standard IgE testing alone, helping to identify children at highest risk of severe reactions.
Symptoms of Nut Allergy
Mild
- Itching or tingling of the mouth and lips
- Mild hives or skin redness
- Runny nose or sneezing
Moderate
- Widespread urticaria (hives)
- Vomiting and abdominal pain
- Swelling of lips or face (angioedema)
Severe (Anaphylaxis)
- Throat tightening or swelling
- Difficulty breathing or wheezing
- Drop in blood pressure, dizziness, or collapse

Frequently Asked Questions
What is nut allergy in children?
Nut allergy is an immune-mediated reaction to proteins found in nuts. It is divided into peanut allergy (peanuts are legumes, not true tree nuts) and tree nut allergy (cashew, walnut, almond, hazelnut, pistachio, Brazil nut, pecan, macadamia). Children can be allergic to one or multiple nuts. Nut allergy is one of the most common causes of severe allergic reactions (anaphylaxis) in children.
What are the symptoms of nut allergy in children?
Symptoms typically appear within minutes to two hours of exposure and can range from mild to severe. Mild symptoms include itching or tingling of the mouth and lips, hives, and mild swelling. Moderate symptoms include vomiting, abdominal pain, and widespread urticaria. Severe symptoms (anaphylaxis) include throat swelling, difficulty breathing, a drop in blood pressure, and loss of consciousness. Any child with throat swelling or breathing difficulty requires immediate emergency treatment.
How is nut allergy diagnosed?
Diagnosis is based on a detailed clinical history combined with allergy testing. Skin prick testing (SPT) with nut extracts and/or specific IgE blood tests (RAST) to individual nuts are used to confirm sensitisation. Component-resolved diagnostics (CRD) — testing to specific nut proteins such as Ara h 2 for peanut — can help assess the risk of severe reactions. Results are interpreted alongside the clinical history.
Do I need a GP referral to see Dr Anandarajan about my child's nut allergy?
No. You can book directly without a GP referral. Dr Anandarajan sees children aged 0–16 with suspected or confirmed nut allergy at Kingsbridge Private Hospital and Ulster Independent Clinic in Belfast.
Will my child need an adrenaline auto-injector (EpiPen)?
An adrenaline auto-injector (AAI) — such as an EpiPen or Jext — is prescribed for children who have had a previous anaphylactic reaction or who are assessed to be at significant risk of anaphylaxis. Dr Anandarajan will assess your child's risk and prescribe an AAI where appropriate, along with a written anaphylaxis emergency action plan and training on how to use the device.
Can nut allergy be outgrown?
Peanut allergy is outgrown in approximately 20% of children, particularly those with lower levels of specific IgE. Tree nut allergies are less commonly outgrown. Regular allergy review is important to monitor whether tolerance has developed. Oral immunotherapy (OIT) for peanut allergy is an emerging treatment option that may be suitable for some children.
How do I manage nut allergy at school?
Key steps include providing the school with a written anaphylaxis emergency action plan, ensuring two in-date adrenaline auto-injectors are kept at school, educating school staff on recognition and treatment of anaphylaxis, and working with the school to implement appropriate allergen avoidance measures. Dr Anandarajan can provide the necessary documentation and guidance.
What is the difference between a nut allergy and a nut intolerance?
A nut allergy involves an immune response (IgE-mediated) that can cause rapid and potentially life-threatening symptoms. A nut intolerance is a non-immune reaction that typically causes digestive symptoms (bloating, discomfort) but is not life-threatening and does not require an adrenaline auto-injector. True nut allergy must be distinguished from intolerance through proper allergy testing.
