Lung disease
Definition
Lung disease is any disease or disorder where lung function does not work properly. There are three main types of lung disease:
- Obstructive lung disease -- a decrease in the exhaled air flow caused by a narrowing or blockage of the airways, which can occur with asthma, emphysema, and chronic bronchitis.
- Restrictive lung disease -- a decrease in the total volume of air that the lungs are able to hold. Often, this is due to a decrease in the elasticity of the lungs themselves or caused by a problem related to the expansion of the chest wall during inhalation.
- A defect in the ability of the lung's air sac tissue to move oxygen into a person's blood.
Most lung diseases actually involve a combination of these categories, such as emphysema, which involves both airflow obstruction and oxygenation problems.
Major lung diseases include:
- Asthma
- Chronic bronchitis
- COPD (chronic obstructive pulmonary disease)
- Emphysema
- Interstitial lung disease
- Pulmonary fibrosis
- Sarcoidosis
Other lung diseases include:
- Asbestosis

- Eosinophilic pneumonia
- Lung cancer
- Metastatic lung cancer
- Necrotizing pneumonia
- Pleural effusion
