Coughing up blood
Hemoptysis; Spitting up blood; Bloody sputum
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.
Considerations
Coughing up blood is not the same as bleeding from the mouth, throat, or gastrointestinal tract.
Blood that comes up with a cough often looks bubbly because it is mixed with air and mucus. It is most often bright red, although it may be rust-colored. Sometimes the mucus contains only streaks of blood.
The outlook depends on what is causing the problem. Most people do well with treatment to treat the symptoms and the underlying disease. People with severe hemoptysis may die.
Causes
A number of conditions, diseases, and medical tests may make you cough up blood. These include:
- Blood clot in the lung
- Breathing food or other material into the lungs (pulmonary aspiration)

Home Care
Medicines that stop coughing (cough suppressants) may help if the problem comes from heavy coughing. These medicines may lead to airway blockages, so check with your doctor before using them.
Keep track of how long you cough up blood, and how much blood is mixed with the mucus. Call your doctor any time you cough up blood, even if you do not have any other symptoms.

What to Expect at Your Office Visit
In an emergency, your health care provider will give you treatments to control your condition. The provider will then ask you questions about your cough, such as:
- How much blood are you coughing up? Are you coughing up large amounts of blood at a time?
- Do you have blood-streaked mucus (phlegm)?
- How many times have you coughed up blood and how often does it happen?
- How long has the problem been going on? Is it worse at some times such as at night?
- What other symptoms do you have?
The provider will do a complete physical exam and check your chest and lungs. Tests that may be done include:
