The term Chronic Obstructive Pulmonary Disease (COPD) covers those long term lung conditions which are characterised by shortness of breath, such as chronic bronchitis and emphysema. Whilst each condition can occur on its own, many people have a mixture of the two problems. COPD usually occurs in people who have smoked or continue to smoke cigarettes. Exposure to irritants like dust and fumes can also increase the risk of developing COPD1.
