What is pulmonary emphysema?

Emphysema is a chronic lung condition in which the alveoli, or air sacs, may be:

Overinflation of the air sacs is a result of a breakdown of the walls of the alveoli. It causes a decrease in respiratory function and breathlessness. Damage to the air sacs is irreversible and results in permanent "holes" in the tissues of the lower lungs.

What is Chronic Obstructive Pulmonary Disease (COPD)?

COPD is a term that refers to a large group of lung diseases that can interfere with normal breathing. According to the American Lung Association, more than 12 million Americans have COPD, and an additional 12 million may have impaired lung function, suggesting it may be significantly underreported. As many as 24 million people may be affected. The two most common conditions of COPD are chronic bronchitis and emphysema.

The causes of COPD are not fully understood. It is generally agreed that the most important cause of chronic bronchitis and emphysema is cigarette smoking. Causes such as air pollution and occupational exposures may play a role, especially when combined with cigarette smoking. Heredity also plays a contributing role in some patients' emphysema, and is especially important in a rare form due to alpha 1 anti-trypsin deficiency.

Patients with chronic bronchitis usually have a cough and sputum production for many years before they develop shortness of breath.

Patients with emphysema usually have shortness of breath and develop a cough and sputum during a respiratory infection, or in the later stages of the illness.
