[|Human|] I am a 59 year old white male with lung disease. Asbestos plaques and now bronchiectasis. Mild emphysema I m told. Here is the problem though, with this diagnosis, what is causing me to have shortness of breath when I walk, excer t (mildly) and cause me to break out in a sweat, get light headed and dizzy, near passing out?
[|AI|]  Thanks for your question on Chat Doctor. Since you are a diagnosed case of bronchiectasis and chronic bronchitis, your shortness of breath can be explained by these.1. Both of these are obstructive airway diseases. Which causes bronchospasm and thus lungs are not properly oxygenated. 2. Both of these can cause structural changes in lung, thus decreasing total lung surface and thus causing poor lung function.3. Infections are easily occurred in diseased lung. This will further hamper lung functions. So your these diseases makes you breathless. Better to consult pulmonologist and get done PFT (Pulmonary Function Test) to know about your lung function. Start treatment and repeat the PFT and see for improvement.
