What is COPD?

COPD stands for chronic obstructive pulmonary disease. This is a term used for a number of conditions; including chronic bronchitis and emphysema. COPD leads to damaged airways in the lungs, causing them to become narrower and making it harder for air to get in and out of the lungs. The word 'chronic' means that the problem is long-term. Some definitions

: -Chronic bronchitis: bronchitis means 'inflammation of the bronchi'. These are the tubes or airways which carry oxygen from the air through the lungs. This inflammation increases mucus production in the airways, producing phlegm which makes you cough.

 -Emphysema: this is where the alveoli (air sacs) in the lungs lose their elasticity. This reduces the support of the airways, causing them to narrow. It also means the lungs are not as good at getting oxygen into the body, so you may have to breathe harder. This can result in shortness of breath.

What causes COPD? The most common cause of COPD is smoking. Once you give up smoking, you gradually reduce the chances of getting COPD - and you slow down its progress if you already have it. Occupational factors, such as coal dust, and some inherited problems can also cause COPD. Whether pollution is a factor is under investigation.
