What is emphysema?

Answer 2

Emphysema is a type of lung disease characterised by shortness of breath. Many people with emphysema also have chronic bronchitis. A combination of the two lung diseases is commonly called chronic obstructive pulmonary disease (COPD).

The exchange of oxygen and carbon dioxide takes place in the small air sacs of the lungs (alveoli). In a person with emphysema, the alveoli are damaged. The main tubes leading into the lungs (the bronchi) are also damaged and narrowed.

Emphysema is generally caused by cigarette smoking or long term exposure to certain industrial pollutants or dust. A small percentage of cases are caused by the inherited disorder alpha-1-antitrypsin deficiency.

The damaged airways don’t regenerate and there is no cure.

Answer 3

Emphysema is a long-term, progressive disease of the lung that primarily causes shortness of breath. In people with emphysema, the lung tissues necessary to support the physical shape and function of the lung are destroyed. It is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs). Emphysema is called an obstructive lung disease because the destruction of lung tissue around smaller airways, called bronchioles, makes these airways unable to hold their shape properly when you exhale.
