Hemoptysis (Coughing Up Blood): Causes & Diagnosis
A clear guide to coughing up blood, covering possible causes, the diagnostic workup and when to seek urgent care.
Treatment usually begins with
Urgent Assessment
Chest Imaging
Bronchoscopy
Evaluation focuses on quickly identifying the source and cause, from a minor airway issue to a more significant underlying condition.
You may need this evaluated if...
A hemoptysis evaluation is recommended when:
- Any amount of blood in coughed-up sputum
- Blood-streaked mucus that persists or recurs
- Coughing up blood alongside chest pain or breathlessness
- Coughing up blood with unexplained weight loss
Most causes of coughing up blood are identifiable and treatable, and prompt evaluation ensures nothing serious is missed.
What is Hemoptysis (Coughing Up Blood)?
Hemoptysis is coughing up blood or blood-streaked mucus from the respiratory tract, and always warrants evaluation to identify the underlying cause.
Never Ignore It
Even a small amount of blood should be evaluated.
Many Possible Causes
Infections, bronchiectasis and, less commonly, tumours can all cause it.
Amount Matters
The volume of blood helps guide how urgently evaluation is needed.
Usually Treatable
Most underlying causes respond well to appropriate treatment.
Common Symptoms
- Blood-streaked or blood-tinged sputum
- Coughing up larger amounts of blood in severe cases
- Associated cough, chest pain or breathlessness
- Fatigue if bleeding is significant or recurrent
What Increases Your Risk
A combination of medical, environmental and lifestyle factors can increase the likelihood of this condition.
How It Is Diagnosed
A structured assessment confirms the diagnosis and helps guide the right treatment plan.
Chest X-Ray or CT Scan
Identifies the likely source and any underlying lung abnormality.
Bronchoscopy
Directly visualises the airway to locate the bleeding source.
Blood Tests
Check clotting function and overall health status.
Sputum Testing
Screens for infection, including tuberculosis.
Treatment Approaches
Medical Care
- Treatment of the underlying cause, such as infection or bronchiectasis
- Review of blood-thinning medication where relevant
- Close monitoring for recurrent or worsening bleeding
Procedural Care
A procedure to seal the bleeding vessel (bronchial artery embolisation) or surgery is considered for significant or recurrent bleeding.
Treatment decisions are based on symptoms, test results, lung function and overall health, not a single test.
Know When to Act
Recognising these signs early and acting promptly is important for the best outcome.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing symptoms.
- Blood-streaked sputum needing evaluation
- Recurrent episodes over recent weeks
Seek Urgent Care
Call for emergency care immediately if you notice any of the following.
- Coughing up a large amount of blood
- Blood in sputum with severe breathlessness
