[|Human|] Hi I just got a call from my friend who has gone to hospital for coughing and throwing up blood. He threw up 200mls before and they did an ECG I think it was on him and found black spots on his lungs... He doesnt smoke... I cant get hold of him now but what could be the possible causes of this? Im really worried :(
[|AI|]  Thanks for your question on Chat Doctor. I can understand your friends situation and problem. He is having hemoptysis (blood in sputum) and his hemoptysis is heavy and severe. His chest x-ray is suggestive of spots. So possibility of lung Infection like pneumonia, tuberculosis is more. Another possibility for his symptoms is Pulmonary embolism and bronchitis. So better to consult pulmonologist and get done PFT (Pulmonary Function Test), sputum examination and CT thorax to rule out above-mentioned possible causes. Better to first diagnose him and then start appropriate treatment. Hope I have solved your query. Wishing good health to your friend. Thanks.
