What is coughing blood?

Coughing blood is the production of blood or bloody mucus from the respiratory tract, which includes the lungs and main air passages. Coughing up blood from the respiratory tract is also called hemoptysis.

Respiratory Problems Spotlight

The most common causes of coughing blood are bronchitis, lung cancer, pneumonia, tuberculosis, lung abscess, bronchiectasis (inflammation of the airways), and pulmonary embolism (blockage of the main lung artery). However, even medical tests and procedures can lead to coughing up blood, such as a bronchoscopy, respiratory tract biopsy, or tonsillectomy.

A bloody cough is usually bubbly or frothy because it is mixed with air and mucus from the lungs. You may have large amounts of blood (one or more teaspoons) or the mucus may appear streaked with blood, which can be bright red, pink, or brick-colored.

From a clinical perspective, a physician will first determine if you are truly coughing up blood from the lungs or if the blood is coming from the gastrointestinal tract (stomach or esophagus) or the upper airway (throat and nasal passages). Blood from the throat due to a violent, unrelenting cough (spitting blood), or the gastrointestinal tract due to a bleeding peptic ulcer is not the same as coughing up blood.

If you are coughing blood with chest pain, dizziness, fever, lightheadedness, or bloody stools or urine you should be immediately evaluated in an emergency setting. In addition to these types of symptoms, you should seek immediate medical care (call 911) if you are coughing up large amounts of blood (several teaspoons with each cough) and bleeding that won’t stop since these are medical emergencies. You should contact a medical professional any time you cough up blood or if you are concerned about the color, consistency, or amount of liquid or mucus produced from your cough.
