[|Human|] Hello, from last 2 days i am caughing (medium), but today i found some blood mix with spit(like air boobles),what could be the reason?. It only happens once, after that i drink lots of water i can feel remaining blood i drunk with water, but im feel ok now cough was reduced, almost gone
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Blood in sputum is known as hemoptysis. In your case possibility of friction bleeding due to coughing is more. Other causes for hemoptysis are pneumonia, tuberculosis, bronchiectasis, bronchitis and lung cancer. So better to get done chest x-ray to rule out all these lung related causes. If chest x-ray is normal than no need to worry much. You are mostly having friction bleeding due to coughing. Hope I have solved your query. Wish you good health. Thanks.
