Causes of shortness of breath
Shortness of breath has lots of different causes.
Common causes include:

But sometimes shortness of breath could be a sign of something more serious, such as:
- a lung condition called chronic obstructive pulmonary disease (COPD)

Any treatment you may need depends on what's causing your symptoms.
Do not try to self-diagnose the cause of shortness of breath – always see a GP.
