Chronic Obstructive Pulmonary Disease (COPD)
Description
Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disorder that makes breathing difficult. It is characterized by airflow limitation that is usually irreversible, and is caused by damage to the airways and lungs. The two main types of COPD are emphysema and chronic bronchitis.
Emphysema occurs when the air sacs in the lungs (alveoli) are damaged and lose their elasticity. This makes it difficult for the lungs to exchange oxygen and carbon dioxide, leading to shortness of breath.
Chronic bronchitis occurs when the airways in the lungs become inflamed and thickened. This produces excessive mucus, which can block the airways and make breathing difficult.
Associated Diseases
COPD is often associated with other respiratory conditions, such as:
- Asthma
- Bronchitis
- Pneumonia
- Lung cancer
People with COPD are also more likely to develop cardiovascular disease, osteoporosis, and depression.
