slp4COPD. Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term used to describe progressive lung diseases including emphysema, chronic bronchitis, refractory (non-reversible) asthma, and some forms of bronchiectasis. This disease is characterized by increasing breathlessness. Many people mistake their increased breathlessness and coughing as a normal part of aging.
COPD affects an estimated 24 million individuals in the U.S., and over half of them have symptoms of COPD and do not know it.
