[|Human|] Im a 1-2 pack a day smoker.  I have developed a hacking morning cough that turns to a choking cough if I have a cigarette.  After a coughing fit I have trouble catching my breath and once actual had the dry heaves following a coughing fit.  I know stop smoking....easier said than done...what does this sound like? COPD? EMPHESEMA? CANCER
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Since you are a active smoker, these symptoms are more suggestive of COPD (chronic obstructive pulmonary disease). Early stage of lung cancer will also cause similar symptoms. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Chest x-ray and CT scan of thorax (if required) for lung cancer. 3. PUT (pulmonary function test). PFT will not only diagnose COPD, but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilator and inhaled corticosteroids (ICS). In any case, smoking cessation should be done as soon as possible. So quit smoking and consult pulmonologist. First diagnose and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
