Hi, Katharina. It is good to hear that you have completely stopped smoking
and this will definitely brings good impact on your health.
First, I want to mention that COPD is a disease of old age usually 6th decade where the patient usually smoke lifelong. So, it is a less probability for you to suffer from COPD. The patient with COPD coughs a lot and produces sputum most of the time of the year. You didn't mention any history of cough.
Now come to the problem of breathing difficulty. Panic attack
itself can cause it without any lung diseases. Other possibilities are Asthma
, Bronchiectesis..etc etc. For a definitive diagnosis consult with a pulmonologist.
is a severe form of COPD and the paient usually die from respiratory failure
. Don't worry, I believe you are not suffering from fatal form of COPD. Hope, this helps. If you have any other query then don't hesitate to ask me. :)
