What does coughing up blood feel like with tuberculosis?

You may feel a forceful cough coming from the chest, followed by a warm, metallic-tasting fluid or blood-streaked phlegm in the mouth. The material can be bright red, dark red, or rusty-looking. Tuberculosis may also cause a cough that persists, chest discomfort, tiredness, fever, night sweating, or loss of appetite. The appearance alone cannot show whether tuberculosis is present; other lung conditions can also cause blood in sputum.

Arrange medical assessment promptly, especially if the blood has appeared more than once or comes with a continuing cough. A clinician may ask about contact with tuberculosis, examine your breathing, and arrange tests such as a chest image or sputum testing. Keep track of when the blood appears, its colour, and whether it is mixed with mucus. Avoid sharing enclosed air closely with others until a clinician advises you, particularly if tuberculosis is being considered.

Seek emergency care if you are coughing up more than a small streak, the bleeding does not stop, or you have shortness of breath, chest pain, faintness, confusion, or blue lips. Urgent assessment is also needed when bleeding is increasing or you feel suddenly much weaker. Do not drive yourself if breathing is difficult or you feel faint.

Ask what tests are needed to check for tuberculosis and other causes of bleeding, whether you should limit close contact while testing is underway, and what symptoms should prompt emergency help. Tell the clinician about medicines that affect bleeding, recent travel or exposure, fever, night sweating, and any change in your breathing.
