What is the cause of cough and bleeding?

There are many reasons for coughing and bleeding. If the capillary tear on the bronchus is caused by a hard cough, the amount of bleeding is generally small and it will heal automatically without any treatment. Be careful not to cough too much in the future. Secondly, many diseases can also cause hemoptysis.

Such as: bronchial diseases-bronchiectasis, primary bronchial lung cancer, etc.

Lung diseases-tuberculosis (the main cause of hemoptysis), pneumonia, lung abscess, etc.

cardiovascular disease

Pulmonary congestion caused by mitral stenosis is more common.

Followed by pulmonary edema caused by left ventricular dysfunction.

Congenital heart disease can also cause hemoptysis due to pulmonary hypertension.

Others-infectious diseases, blood diseases, rheumatism, etc.

Among them, tuberculosis is the most common. If you have a long history of cough, I suggest you go to the hospital for an X-ray examination to find out the cause.
