Chronic obstructive pulmonary disease
COPD: A group of lung diseases that block airflow and make it difficult to breathe.
Emphysema and chronic bronchitis are the most common conditions that make up COPD. Damage to the lungs from COPD can't be reversed.
Symptoms include shortness of breath, wheezing or a chronic cough.
Rescue inhalers and inhaled or oral steroids can help control symptoms and minimise further damage.
