COPD is a combination of lung diseases, such as chronic bronchitis and emphysema, that can make it hard to breathe. Its symptoms are similar to asthma.
COPD is usually preventable. Smoking is the main cause of COPD, and smokers are at a greater risk of having both asthma and COPD.
It is important to make a proper diagnosis of asthma and/or COPD because treatment can differ.
COPD is managed with bronchodilators, inhaled corticosteroids and lifestyle management.
