Chronic Cough: Causes, Diagnosis & Treatment
A clear guide to chronic cough lasting more than eight weeks, covering possible causes, diagnostic workup and treatment.
Treatment usually begins with
Pulmonologist Assessment
Chest Imaging
Lung Function Tests
Cause-Directed Treatment
Evaluation systematically works through the most common causes to identify what's driving your cough.
You may need this evaluated if...
A chronic cough evaluation is recommended when:
- Cough lasting more than eight weeks
- Cough disrupting sleep or daily life
- Cough with phlegm, wheeze or breathlessness
- Cough not improving with over-the-counter treatment
Chronic cough almost always has an identifiable, treatable cause, and a structured evaluation gets to the answer.
What is Chronic Cough?
A chronic cough is a cough that lasts more than eight weeks, and is one of the most common reasons for a pulmonology consultation, usually pointing to an underlying, treatable cause.
Very Common
One of the most frequent reasons patients see a specialist.
Multiple Common Causes
Asthma, acid reflux and post-nasal drip account for most cases.
Systematic Evaluation
A step-by-step workup identifies the cause in the large majority of patients.
Treatable
Addressing the underlying cause resolves the cough in most cases.
Common Symptoms
- Cough lasting more than eight weeks
- Cough that worsens at night or with certain triggers
- Associated wheeze, heartburn or postnasal drip
- Occasional cough-related chest discomfort
What Increases Your Risk
A combination of medical, environmental and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Detailed Clinical History
Reviews the cough pattern, triggers and associated symptoms.
Chest X-Ray
Rules out a structural or infectious cause in the lungs.
Spirometry
Checks for underlying asthma or other airway conditions.
Further Targeted Testing
Assesses for reflux or sinus causes when clinically indicated.
Treatment Approaches
Medical Care
- Treatment directed at the identified cause, such as asthma or reflux medication
- Review and adjustment of contributing medications
- Postnasal drip management where relevant
Procedural Care
Surgery is not part of routine chronic cough treatment and is reserved for a specific structural cause identified during evaluation.
Treatment decisions are based on symptoms, test results, lung function and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
