Coughing Up Blood (Hemoptysis): Causes, Symptoms, Diagnosis, & Treatments


Hemoptysis, or coughing up blood, can be triggered by infections, inflammation, allergies, or chronic diseases such as obstructive pulmonary disease and lung cancer. Like any other symptom, you should rule out mild and severe causes of hemoptysis before starting your treatment.

Coughing up blood is not always a symptom of a life-threatening disease. It depends on the severity and extent of the disease. However, if you start coughing up blood, it is recommended to seek medical help as soon as possible to know the cause and start your treatment.
