What are the abnormalities (diseases) in smoker's lung?
The major abnormalities in smoker's lung are grouped under the label of chronic obstructive pulmonary disease (COPD). It is estimated that 40 million people worldwide suffer from COPD. COPD is the 4th leading cause of death in the USA. Even more disturbing is the fact that COPD is the only one of the "top 5" causes of death to increase in the past decade. While COPD has been thought of as a disease of men, it is estimated that by the year 2010 there will be more women than men affected by COPD. These statistics are especially sad because COPD is preventable disease by stopping smoking; unfortunately, this is easier said than done. About 70% of smokers want to quit, but only 7% who try are smoke free after one year; however, one should not give up. Numerous tries, sometimes more than 10, and professional help often are needed, but the health benefits of smoking cessation make it worth the effort.
COPD is made up of two major, related diseases. One, emphysema, involves the lung alveoli, and the other, chronic bronchitis, involves the bronchial airway. (Both conditions are discussed below.) In this essay, I will use the term chronic bronchitis to include chronic bronchiolitis and chronic respiratory bronchiolitis. I do this because these three conditions have the same pathology (structural abnormalities), cause the same symptoms, and differ only in their location in the airway. At any rate, some smokers primarily have emphysema and some primarily have chronic bronchitis. Most, however, have a combination of these two diseases.
