Chronic obstructive pulmonary disease also called as COPD, is a group of progressive lung diseases that limit the airflow into the lungs. The most common among COPD diseases are emphysema and chronic bronchitis. Most of the people with COPD suffer from both of these conditions.
COPD exacerbations are sudden flare ups in acute respiratory symptoms in people diagnosed with severe COPD (chronic obstructive pulmonary disease). They cause difficulties in an already serious condition. People may be able to avoid flare-ups or better manage the symptoms by understanding triggers of COPD exacerbations.
End stage COPD symptoms are worse as compared to its initial stages. The most common symptom is feeling out of breath. Some people’s breathing might get worse much rapidly, over weeks or months. People with end stage COPD show a noticeable, gradual worsening of their breathing.
