[|Human|] I have had experiences over the past 2 years of episodes of coughing, production of mucus, wheezing and I have been to a doctor who says my lungs are clear. But I am thinking I may have COPD. Never smoked, but was in a second hand smoke home during much of my childhood (friend). How is the best way to diagnose and treat COPD.
[|AI|]  Hello, Yes, you're all symptoms, cough, wheezing, mucus production are commonly seen with COPD (chronic obstructive pulmonary disease). PUT (Pulmonary Function Test) is a must for the diagnosis of COPD. So, it is better to consult pulmonologist and get done PFT. PFT will not only diagnose bronchitis, but it will also tell you about the severity of the disease and treatment is based on severity only. You may need inhaled bronchodilators (formoterol or albuterol) and inhaled corticosteroid (ICS) (budesonide or fluticasone). Hope I have answered your query. Let me know if I can assist you further.
