Chronic cough
Overview
Chronic cough affects breathing, the airway or lungs in children. Severity is judged by breathing effort and oxygenation, not by cough or noise alone.
Children vary in development, symptoms and response to treatment. This guide cannot diagnose a child and should support, not replace, individual professional care.
Signs and symptoms
Cough, wheeze, breathlessness, noisy breathing, chest discomfort, exercise limitation or disturbed sleep may occur.
Look at the whole child, including comfort, alertness, breathing, drinking, urine output, sleep, growth, learning and participation in usual activities.
Causes
Viral illness, airway inflammation, allergy, inhaled material, anatomical narrowing or another lung or heart condition can contribute.
Risk factors
Prematurity, smoke or pollution exposure, allergy, family history and chronic heart, lung or neuromuscular conditions can increase risk. Risk factors are not diagnostic, and some affected children have none.
Diagnosis
Assessment includes respiratory rate, effort, oxygen level and chest examination. Lung-function tests, imaging or sleep studies may be appropriate.
Treatment options
Care may include trigger reduction, inhaled medicine with a spacer, oxygen, antibiotics for selected infections, or removal of an inhaled object.
Plans should be age appropriate, family centred and reviewed as the child grows. Medicines must be used only at the recommended dose and with professional guidance.
Home management
Follow the written action plan, check inhaler technique, avoid smoke exposure and monitor sleep, exercise and night symptoms.
Prevention
Smoke-free air, vaccination, hand hygiene and good control of known asthma or allergy reduce avoidable respiratory illness.
Long-term outlook
Many childhood respiratory problems improve, while chronic conditions benefit from regular review and correct technique.
Possible complications
Poorly controlled breathing problems can disrupt sleep, activity and growth; severe episodes can reduce oxygen and require hospital care.
When to seek urgent medical care
Emergency help is needed for struggling to breathe, inability to speak or drink, blue-grey colour, marked chest recession, exhaustion or sudden symptoms after choking.
Call emergency services for severe breathing difficulty, blue or grey colour, collapse, a seizure lasting longer than local emergency guidance, reduced responsiveness or rapidly worsening illness.
Frequently asked questions
Does my child need tests?
Not always. Testing depends on age, history, examination and whether a result will change treatment.
Can my child attend school?
Many children can participate with suitable adjustments. Keep a child home when acutely unwell and follow the care plan and local attendance guidance.
When should we arrange follow-up?
Use the schedule given by the healthcare team and request earlier review for worsening symptoms, new concerns, treatment side effects or changes in growth, learning or daily function.
Summary
Breathing effort and the child’s overall condition determine how urgently care is needed.
