A graduate of Yale University, Carey Hagan holds a master of arts in English in addition to her BA in English and Russian literature. Professionally, Carey Hagan served as an assistant cataloger at the library of the Catholic University and as a librarian at the Fairfax County Public Library. In her free time, she likes hiking and bird watching and supports health education in conditions such as COPD. Chronic obstructive pulmonary disease, or COPD, is a condition that involves the inflammation of the lungs and obstructs airflow. COPD can be caused by smoking or exposure to gases or matter that affect the lungs. If not treated in the early stages it can lead up to heart disease or lung cancer. Symptoms of COPD can include shortness of breath and chest tightness which can often happen during physical activities. There are two types of COPD such as emphysema and chronic bronchitis which can be developed together. Emphysema occurs when alveoli from small air passages are destroyed by smoke or other irritating gases. Chronic bronchitis resembles inflammation of the bronchial tubes which can also narrow and reduce air flow. Chronic bronchitis can also result in an increased amount of mucus produced by the lungs which can restrict air flow even more due to the narrowed tubes.
