Hay Fever Belfast

Hay fever (allergic rhinitis) affects around 1 in 5 children in the UK and is a leading cause of poor sleep, reduced concentration and underperformance at school — particularly during exam season. Effective treatment makes a significant difference.

Overview

Hay fever (seasonal allergic rhinitis) is an IgE-mediated allergic reaction to airborne pollen — most commonly grass pollen (May–July), tree pollen (February–May) and weed pollen (June–September). Perennial allergic rhinitis is caused by year-round allergens such as house dust mite, pet dander and mould. Both conditions cause inflammation of the nasal lining (rhinitis) and often the eyes (conjunctivitis). Hay fever is frequently under-treated — many children and parents accept it as an unavoidable seasonal nuisance, when in fact effective treatments are available that can dramatically reduce symptoms. Poorly controlled hay fever significantly impairs sleep, concentration and school performance, and is a major trigger for asthma exacerbations.

Expert paediatric assessment in Belfast — Dr Mugilan Anandarajan (FRCPCH) provides thorough, evidence-based evaluation and management for children aged 0–16. No GP referral required.

Common Symptoms

  • Persistent sneezing — often in bouts, particularly in the morning
  • Runny nose (rhinorrhoea) — clear, watery discharge
  • Blocked nose (nasal congestion) — often worse at night, disrupting sleep
  • Itchy nose, roof of mouth, throat or ears
  • Watery, red, itchy eyes (allergic conjunctivitis)
  • Puffy or swollen eyelids
  • Post-nasal drip — mucus dripping down the back of the throat causing cough
  • Reduced sense of smell (hyposmia)
  • Fatigue and poor concentration — often mistaken for laziness or lack of motivation
  • Worsening of asthma symptoms during pollen season
  • Headache or facial pressure (from nasal congestion)

Causes & Triggers

  • Grass pollen sensitisation — the most common cause of seasonal hay fever in the UK (May–July)
  • Tree pollen sensitisation — birch, alder, hazel (February–May)
  • Weed pollen sensitisation — nettle, plantain, mugwort (June–September)
  • House dust mite — the most common cause of perennial (year-round) allergic rhinitis
  • Pet dander — cat and dog allergens are potent triggers
  • Mould spores — Alternaria and Cladosporium peak in late summer and autumn
  • Genetic predisposition — family history of hay fever, asthma or eczema
  • Air pollution — increases pollen allergenicity and nasal mucosal sensitivity
  • Cross-reactivity between pollens and foods — oral allergy syndrome (e.g. birch pollen and apple, hazelnut)

Diagnosis & Testing

Dr Anandarajan takes a detailed history of the pattern and seasonality of symptoms, triggers, response to previous treatments, and any co-existing conditions (asthma, eczema, food allergy). Skin prick testing with a comprehensive panel of aeroallergens — grass pollen, tree pollens, weed pollens, house dust mite, cat, dog and mould — identifies the specific sensitisations driving symptoms. Specific IgE blood tests are used where skin testing is not possible (e.g. in children with extensive eczema or those taking antihistamines). Nasal endoscopy or imaging is not routinely required but may be recommended if structural causes (nasal polyps, deviated septum) are suspected.

  • Skin prick testing (SPT) — comprehensive aeroallergen panel including grass, tree and weed pollens, house dust mite, cat, dog, mould
  • Specific IgE blood tests (ImmunoCAP) — for individual aeroallergens
  • Component-resolved diagnostics — Phl p 5 (grass), Bet v 1 (birch), Alt a 1 (Alternaria)
  • Nasal provocation testing — for equivocal cases
  • Smell testing — where hyposmia is a significant symptom
  • Assessment of co-existing asthma — spirometry, FeNO where indicated

Management & Treatment

Management of hay fever follows a stepwise approach. Intranasal corticosteroids (INCS — nasal steroid sprays) are the most effective treatment for nasal symptoms and should be started 2 weeks before the expected pollen season. Non-sedating antihistamines (cetirizine, loratadine, fexofenadine) provide additional relief for sneezing, itching and eye symptoms. Topical antihistamine or sodium cromoglicate eye drops are used for allergic conjunctivitis. For children with moderate-to-severe hay fever not adequately controlled by pharmacotherapy, allergen immunotherapy (AIT) — sublingual grass pollen tablets or drops — is a disease-modifying treatment that can provide long-term symptom reduction and reduce the risk of developing asthma. Dr Anandarajan also advises on practical pollen avoidance measures and the importance of treating co-existing asthma.

  • Intranasal corticosteroid spray (INCS) — first-line treatment; started 2 weeks before pollen season
  • Non-sedating oral antihistamine (cetirizine, loratadine, fexofenadine) — for sneezing, itching and eye symptoms
  • Antihistamine or sodium cromoglicate eye drops — for allergic conjunctivitis
  • Leukotriene receptor antagonist (montelukast) — particularly useful when hay fever and asthma co-exist
  • Nasal saline irrigation — adjunct to reduce pollen load and improve nasal clearance
  • Sublingual allergen immunotherapy (SLIT) — grass pollen tablets or drops for disease modification
  • Subcutaneous allergen immunotherapy (SCIT) — for multi-sensitised children or those unsuitable for SLIT
  • Treatment of co-existing asthma — optimised inhaler therapy during pollen season
  • Practical pollen avoidance advice — pollen forecasts, wraparound sunglasses, showering after outdoor activity

When to Seek a Specialist Opinion

Hay fever symptoms are significantly affecting your child's sleep or school performance
Over-the-counter antihistamines are not providing adequate relief
Your child's asthma worsens during pollen season
You want to identify the specific pollens or allergens triggering your child's symptoms
You want to explore allergen immunotherapy as a long-term solution
Your child has hay fever alongside eczema, food allergy or asthma
Symptoms are present year-round (suggesting perennial allergic rhinitis)
Your child has significant eye symptoms alongside nasal symptoms
Hay fever is affecting your child during important school exams

Common Questions

Frequently Asked Questions

Questions parents commonly ask about hay fever in children — answered by Dr Mugilan Anandarajan, Consultant Paediatrician, Belfast.

Intranasal corticosteroid sprays (INCS) — such as fluticasone, mometasone or budesonide nasal spray — are the most effective treatment for nasal symptoms of hay fever. They work best when started 2 weeks before the pollen season begins and used consistently throughout the season. They are safe for long-term use in children. Antihistamines are useful for sneezing, itching and eye symptoms but are less effective than INCS for nasal congestion.
Yes — significantly. Studies have shown that poorly controlled hay fever reduces concentration, impairs memory and increases fatigue. Children with hay fever are more likely to underperform in exams taken during the pollen season. Sedating antihistamines (e.g. chlorphenamine) make this worse. It is important to use non-sedating antihistamines and to start nasal steroid sprays before the pollen season to ensure good symptom control during exam periods.
Allergen immunotherapy (AIT) involves giving gradually increasing doses of the allergen (e.g. grass pollen) to retrain the immune system to tolerate it. Sublingual immunotherapy (SLIT) — grass pollen tablets or drops taken daily under the tongue — is the most practical form for children. It is taken for 3 years and can provide significant, long-lasting symptom reduction even after treatment is stopped. It is not a cure, but it is the only treatment that modifies the underlying allergic disease rather than just suppressing symptoms.
Yes. Hay fever and asthma are closely linked — they are both manifestations of allergic inflammation in the respiratory tract (the 'united airway' concept). Around 80% of children with asthma have allergic rhinitis, and poorly controlled hay fever is a major trigger for asthma exacerbations during pollen season. Treating hay fever effectively — particularly with nasal steroids — can significantly improve asthma control.
In Northern Ireland, the tree pollen season typically runs from February to May (birch, alder, hazel), the grass pollen season from May to July (the most significant for most hay fever sufferers), and the weed pollen season from June to September. Mould spore counts peak in late summer and autumn. Dr Anandarajan will identify your child's specific sensitisations so you know exactly when to start treatment each year.
