COPD affects each person differently. Many people wait until severe lung function decline before seeking the help of a professional. Identifying and treating COPD in its early stages is essential to maintaining a high quality of life.
The cause of COPD is almost always smoking; however, home and work environment can also be a factor.
There are 3 main risk factors:
- Tobacco smoking
- Long-term exposure to irritants
(e.g., chemical fumes, secondhand smoke, air pollution)
- Genetic disorder alpha-1 antitrypsin deficiency
(accounts for one percent of COPD cases)
