Chronic obstructive pulmonary disease is a group of diseases that cause airflow blockage and extreme breathing problems to the point of breathlessness.
Most commonly referred to as COPD, the term describes emphysema and chronic bronchitis. COPD also includes bronchiectasis and, in some patients, asthma. COPD gets worse as it progresses and, in late stages, a person may experience extreme breathlessness at all times, even when they are sitting still. COPD often goes undiagnosed and can be life-threatening if not properly treated.
An acute exacerbation of COPD refers to a flare-up or episode where a person's breathing becomes worse than normal. This can lead to life-threatening complications depending on the cause and severity.
