COPD is a chronic condition marked by persistent narrowing of the airways and difficulty breathing. This page gives general information about COPD, common symptoms, risk factors and guidance on which specialists to see. For personalized diagnosis or treatment, consult a healthcare professional.
COPD is a long-term respiratory condition characterized by airflow limitation, chronic inflammation and damage to lung tissue. Its progression varies between individuals and can affect exercise tolerance, daily activities and overall quality of life.
Cigarette smoking is the leading risk factor for COPD. Other contributors include long-term exposure to secondhand smoke, workplace dusts and chemicals, and prolonged air pollution. Certain genetic conditions, such as alpha-1 antitrypsin deficiency, can increase susceptibility. Risk also rises with age and cumulative exposures.
Frequent signs include chronic cough, sputum production and shortness of breath that worsens with exertion. COPD can be punctuated by exacerbations—periods of sudden symptom worsening often triggered by infections or environmental irritants. Seek urgent care if you experience severe breathlessness at rest, bluish lips or fingertips, sudden confusion, chest pain, or a very high fever.
Diagnosis usually involves spirometry to measure lung function, along with clinical history, physical exam and sometimes imaging or blood tests. Initial assessment can be done by primary care (family medicine); for diagnosis confirmation, long-term follow-up and complex care, a pulmonologist (chest specialist) is the appropriate referral.
The most effective preventive step is quitting tobacco and avoiding smoke exposure. Measures that support respiratory health include improving air quality, following recommended vaccinations, maintaining physical activity and participating in pulmonary rehabilitation when advised. Regular follow-up with a clinician helps monitor disease progression and manage exacerbations.
