Exhaling issues are a symptom of asthma. What's the difference between COPD and asthma?
In asthma, it may be fully reversible. An asthmatic [patient] may have a problem getting air out because the airway is narrowed by a bronchospasm [an abnormal contraction of muscles in the bronchi, large air tubes in the lungs].
However, when you take your quick-relief medicine or a daily controller drug, suddenly airways are open and normal.
Asthma is characterized by significant improvement, if not normalization, after treatment.
And COPD doesn't normalize after treatment?
COPD is characterized by airflow obstruction that's not fully reversible. It may get a little better with medication, but if it doesn't get [significantly] better, that's COPD.
Are COPD patients more likely to be smokers?
If you look in the U.S., 95% of COPD patients have smoked at least a pack a day for 10 years.
If you never smoked and have a COPD diagnosis and you live in this country, it's one of three things:
The most common is the doctor made the wrong diagnosis. We're not supposed to admit mistakes, but, frankly, we make mistakes in medicine.
