This course provides a foundational understanding of COPD. It covers prevalence and mortality statistics, common symptoms, risk factors, the underlying lung changes that cause air trapping and impaired gas exchange, the main causes (primarily smoking), and the two conditions that fall under the COPD umbrella: emphysema and chronic bronchitis. You will also learn about the genetic form of COPD (Alpha-1 Antitrypsin Deficiency) and why co-morbidities matter. All content is drawn directly from the COPD Toolkit Overview section.
