Wheezing in Children

Wheezing is a high-pitched sound caused by narrowed airways, usually heard while breathing out. Viral infections are a common trigger in young children, while recurrent episodes may be associated with asthma, allergy or other airway conditions. The child's age, breathing effort and pattern of recurrence guide evaluation.

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 wheezing always mean asthma?

No. Wheezing can occur with infections and several other conditions, especially in young children.

Can a phone recording help?

A safe recording may help describe an intermittent sound, but it does not replace examination.

Are spacers important?

Yes. Correct spacer technique improves delivery of inhaled medicine in many children.

Can children exercise with asthma?

Most children can remain active when asthma is well controlled and a clinician has provided an appropriate plan.

When should a child go to emergency care?

Seek immediate care for severe breathing difficulty, blue lips, exhaustion or poor response to the child's emergency plan.

Persistent symptoms deserve a clear next step.
