What is the most common reason for coughing up blood (hemoptysis)?

ANSWER

The most common reason for coughing up blood is acute bronchitis, which typically gets better on its own without treatment. People with bronchitis with small amounts of blood in the mucus for less than a week can watch carefully and wait for their condition to improve.
