Natural History of COPD
Um Soo-Jung

Abstract
It has been known that COPD is developed by acceleration of the age-related decline in lung function in susceptible smokers. However, this traditional concept is being challenged by new investigations. The concept that COPD is always progressive and worsens universally is not tenable. In this article, natural history of COPD from recent researches, early COPD and non obstructive pulmonary disease will be reviewed. Early COPD is an important issue because there is a growing body of evidence that treatment may be more beneficial at an earlier stage of COPD. Non obstructive pulmonary disease is thought to be a preclinical stage of COPD. Understanding inception of the disease can lead us to prevent or halt the disease.
