Chronic obstructive pulmonary disease

COPD is an umbrella term that could refer to emphysema and chronic bronchitis and, more commonly, a combination of these conditions. Asthma was once classified as a type of COPD and shares some of the same characteristics but it’s now considered a distinct chronic inflammatory disorder. The most common chronic lung disease, COPD affects an estimated 30 million Americans, and its incidence is rising. It now ranks fourth among the major causes of death in the United States.

What causes it:

COPD may result from:

• cigarette smoking

• recurrent or chronic respiratory tract infection

• allergies

• familial and hereditary factors such as alpha1-antitrypsin deficiency.
