Breathlessness is the sensation of not getting enough air. It may come from the lungs, the heart, the blood, or from deconditioning and anxiety.
Respiratory causes
Asthma, COPD, lung infections, interstitial lung disease and pleural fluid can all reduce the lungs' ability to move or transfer air efficiently.
Patterns that help
Breathlessness that comes in episodes with wheeze suggests airway disease. Breathlessness while lying flat may point towards the heart or diaphragm. Gradual worsening over months suggests a chronic lung process.
When to seek urgent care
Sudden severe breathlessness, breathlessness with chest pain, bluish lips or confusion needs immediate medical attention.
