Common signs

What parents may notice

  • Recurring sneezing or blocked nose
  • Itchy or watery eyes
  • Hives or recurring itchy rash
  • Wheezing or cough after exposure
  • Lip or facial swelling
  • Vomiting after a particular food
  • Seasonal symptoms
  • Symptoms around dust, pets or mould
Possible reasons

What can cause it?

Common triggers include dust mites, pollen, mould, pets, foods, insect stings and medicines. Not every rash, cough or stomach symptom is allergic, and testing should be guided by the history rather than ordered as a broad screening panel.

Questions parents ask

The real questions, answered.

Not what we wish you'd ask. What you're actually thinking when you find this page.

Book a consultation
Does a positive allergy test always mean clinical allergy?

No. Results must be interpreted with the child's actual reaction history.

Can children outgrow allergies?

Some childhood allergies become less likely with age, while others persist. Follow-up should be individualised.

Should foods be removed before assessment?

Avoid unnecessary broad restriction. Remove a food only when advised or when a clear reaction has occurred and urgent safety requires it.

Can allergy cause cough?

Yes, nasal allergy or asthma can contribute, but recurrent cough also has non-allergic causes.

What is an allergy action plan?

It is a written plan explaining avoidance, routine medicine and what to do during a significant reaction.

Persistent symptoms deserve a clear next step.
