What is Chronic Cough?
A chronic cough is defined as a persistent cough lasting longer than 8-12 weeks (or over two months) (1;2). It often begins after a viral infection like the flu, but can also be linked to underlying conditions such as asthma, sinusitis, post-nasal drip, or gastroesophageal reflux disease (GERD).
When a cough persists despite treatment for these known causes, it is termed Refractory Chronic Cough (RCC). In cases where no clear cause can be identified, the condition is referred to as Idiopathic Chronic Cough (3).
Many individuals with chronic cough experience heightened sensitivity in their upper airways, making them overly reactive to irritants like strong odors, dust, or sudden temperature changes. Even everyday activities such as talking or laughing can trigger coughing episodes.

What are the symptoms?
Living with a chronic cough can significantly reduce quality of life. Frequent coughing fits can be physically exhausting and worsen with lack of sleep, leading to extreme fatigue. Many individuals begin avoiding social situations, public spaces, or even public transportation due to embarrassment or discomfort, which may result in social withdrawal and depression (4-7).
In severe cases, persistent coughing can cause physical complications such as:
Rib fractures (from intense coughing strain)
Urinary incontinence (particularly in women)
Syncope (fainting spells due to coughing fits) (7-9)
Diagnosing and Monitoring Chronic Cough
Initial Consultation
The diagnostic process typically begins with a detailed discussion of symptoms with your healthcare provider. Together, you’ll explore potential causes through various tests:
Diagnostic Tests May Include:
Lung Imaging
Chest X-rays or CT scans to identify structural issues or infections
Lab Work
Blood or sputum (phlegm) tests to detect inflammation, infection, or allergic responses
Lung Function Tests
Spirometry (most common): Measures airflow to diagnose asthma or COPD
Additional tests like lung volume or diffusing capacity tests may also be used
Scope Procedures (if initial tests are inconclusive)
Rhinoscopy: A thin, lighted tube examines sinuses and nasal passages
Bronchoscopy: A scope checks airways and lungs; biopsies can be taken if needed
Allergy Testing
Skin tests to identify potential cough triggers (e.g., pollen, dust mites)
Tracking Your Cough
Emerging technologies, including wearable devices and mobile apps, now allow patients and doctors to monitor cough patterns (frequency, intensity, and triggers). This data helps tailor treatments and assess their effectiveness over time (21;22).
