Overview

Coughing up blood is the spitting up of blood or bloody mucus from the lungs and throat (respiratory tract). Hemoptysis is the medical term for coughing up blood from the respiratory tract.

What causes Hemoptysis?

A number of conditions, diseases, and medical tests may make you cough up blood, including:

• Blood clot in the lung
• Breathing blood into the lungs (pulmonary aspiration)
• Bronchoscopy with biopsy
• Bronchiectasis
• Bronchitis
• Cancer
• Cystic fibrosis
• Inflammation of the blood vessels in the lung (vasculitis)
• Injury to the arteries of the lungs
• Irritation of the throat from violent coughing (small amounts of blood)
• Pneumonia or other lung infections
• Pulmonary edema
• Systemic lupus erythematosus
• Tuberculosis

When to seek urgent medical care?

Get medical help right away if you cough up blood and have:

• A cough that produces more than a few teaspoons of blood
• Blood in your urine or stool
• Chest pain
• Dizziness
• Fever
• Light-headedness
• Severe shortness of breath

Diagnosis

In an emergency case, your doctor will give you treatments to control your condition. The doctor will then ask you questions about your cough, such as:

• Type
  • Are you coughing up large amounts of blood (massive hemoptysis)?
  • Can you see blood when you cough up something?
  • How many times have you coughed up blood?
  • Is there blood-streaked mucus (phlegm)?

• Time pattern
  • Did it begin suddenly?
  • Has it increased recently?
  • For how many weeks has the cough lasted?
  • Is the cough worse at night?
  • What other symptoms do you have?

Tests that may be done include:

• Complete blood count
• Bronchoscopy, a test to view the airways
• Chest CT scan
• Chest x-ray
• Lung biopsy
• Lung scan
• Pulmonary arteriography
• Sputum culture and smear
• Test to see if the blood clots normally, such as PT or PTT

Treatment options

Cough suppressants may help if this condition is due to throat irritation from violent coughing. However, cough suppressants may lead to airway blockages in some cases. Always check with your doctor before using them.

It is very important to note how long you cough up blood, and how much blood is mixed with the mucus. Contact your doctor any time you cough up blood, even if you do not have any other symptoms.
