Coughing Up Blood After Bronchitis: Causes & When to Worry

It is not uncommon to cough up blood after having bronchitis. This is because the inflammation and irritation caused by bronchitis can damage the small blood vessels in the lungs, leading to bleeding.

Coughing up small amounts of blood is usually not a cause for concern and should resolve on its own within a few days. However, if you are coughing up large amounts of blood or if the coughing up of blood is accompanied by other symptoms such as chest pain, shortness of breath, or fever, it is important to see a doctor right away. These could be signs of a more serious condition, such as pneumonia or a blood clot in the lungs.
