Why Am I Short of Breath? Common Causes and When to See a Pulmonologist
Shortness of breath has many possible causes. The pattern of your symptoms helps decide when specialist assessment makes sense.

Quick answer
Feeling short of breath can be linked to the lungs, the heart, fitness, weight, anaemia, anxiety and other causes. When it happens, and what comes with it, helps a specialist work out which tests you need.
Does the pattern matter?
Yes. It helps to notice whether breathlessness happens:
- Only with exercise, or also at rest
- When you lie flat or during the night
- With a cough, wheeze or chest tightness
- Suddenly, or slowly over weeks or months
What might a pulmonologist check?
Depending on your symptoms, assessment may include a breathing test such as spirometry, fuller pulmonary function tests, oxygen levels and a review of any imaging.
When should you book an appointment?
See a specialist if breathlessness is new and not going away, is getting worse, limits your daily life, or has not improved with treatment.
When is it an emergency?
Sudden or severe difficulty breathing, chest pain, or blue lips need emergency care. Call 998 or go to the nearest emergency department.
