Chronic cough is defined as a persistent cough lasting more than eight weeks in adults or four weeks in children. While often perceived as a minor symptom, chronic cough can significantly impact quality of life and may indicate underlying respiratory or systemic conditions. In the UAE, environmental factors such as dust exposure, humidity fluctuations, and allergens can contribute to prolonged cough, making specialized evaluation essential.

Common causes of chronic cough include asthma, upper airway conditions, gastroesophageal reflux, smoking-related lung disease, and chronic infections. However, identifying the precise cause requires systematic assessment. Tertiary pulmonology clinics employ structured diagnostic pathways involving detailed medical history, physical examination, lung function testing, and imaging when indicated. Spirometry plays a central role in evaluating airflow limitation and bronchial responsiveness.

When asthma is suspected, bronchial challenge testing or therapeutic trials may be coordinated. In cases with suspected reflux-related cough or upper airway involvement, collaboration with gastroenterology or ENT specialists may be necessary. Multidisciplinary evaluation ensures accurate differentiation between overlapping conditions.

Imaging studies such as chest radiography or computed tomography may be recommended to exclude structural abnormalities, interstitial lung disease, or malignancy. In persistent unexplained cases, bronchoscopy may be considered within tertiary centers to directly visualize airways and obtain samples when clinically appropriate.

Management depends on identifying and addressing the underlying cause. Patient education regarding environmental trigger avoidance, occupational exposure mitigation, and smoking cessation is emphasized. Follow-up visits allow reassessment of symptom progression and evaluation of response to interventions.

Chronic cough clinics in the UAE integrate advanced diagnostic capabilities with multidisciplinary collaboration to ensure comprehensive evaluation. By adopting a systematic, evidence-based approach, tertiary pulmonology services aim to resolve symptoms, prevent complications, and restore respiratory comfort. Early referral to specialized centers enhances diagnostic accuracy and improves long-term outcomes for patients experiencing persistent cough.
