The British Lung Foundation has identified areas across the United Kingdom where people are most at risk of being hospitalized with chronic obstructive pulmonary disease (COPD). Chronic bronchitis and emphysema are common COPDs.

Cigarette smoking is the most common cause, but breathing in other kinds of irritants, like pollution, dust or chemicals, also might cause or contribute to COPD. Quitting smoking is the best way to avoid developing COPD. Treatment can make patients more comfortable, but there is no cure. (© AP Images)
