How common is chronic obstructive pulmonary disease (COPD)?
Chronic obstructive pulmonary disease (COPD) develops over many years (sometimes 10 to 30 years) and is most commonly diagnosed in people older than 60. Because of this, COPD generally is considered a disease of older adults. COPD is sometimes called chronic obstructive lung disease (COLD) or chronic airflow obstruction (CAO). In the United States:1 • About 10 million people have been diagnosed with some form of COPD, and as many as 24 million more may be undiagnosed. • COPD is the fourth most common cause of death. COPD is also a major cause of disability and death worldwide.1 The World Health Organization estimates that by 2020, COPD will become the third most common cause of death worldwide.2 The disease is more common in: • Smokers. Most people with COPD have a history of significant cigarette use.1 • Older adults than younger people. Men and women are affected equally.
