Which of the following is a common manifestation of COPD?

• A. Dyspnea
• B. Chest pain unrelated to breathing
• C. Tinnitus
• D. Hypoglycemia

Answer: (A)

Dyspnea, or shortness of breath, is the most common manifestation of COPD. The disease causes chronic airflow limitation and gas exchange abnormalities, which increase the work of breathing and make even ordinary activity feel difficult. Patients often describe progressive breathlessness that worsens with exertion, and this symptom is typically persistent as COPD advances. While coughing and sputum production are also common, the hallmark feature clinicians look for in COPD is this troublesome dyspnea.

Chest pain unrelated to breathing isn’t a typical COPD feature; it would raise concern for cardiac or other non-pulmonary issues. Tinnitus isn’t associated with COPD, and hypoglycemia is a metabolic problem outside the respiratory system.
