Although several clinical parameters may suggest chronic obstructive pulmonary disease (COPD), evidence shows that a definitive diagnosis cannot be made based solely on clinical features. A high index of suspicion—prompted by characteristic symptoms—should lead to confirmatory testing using spirometry or other lung function assessments. The severity of COPD can then be stratified using validated clinical tools, facilitating classification in line with GOLD (Global Initiative for Chronic Obstructive Lung Disease) criteria. This classification guides the initiation of targeted treatment. Ongoing management, treatment intensification, and specialist referral are determined through periodic evaluation in the ambulatory care setting.
