COPD: COPD stands for for chronic obstructive pulmonary disease. The term obstructive refers to the impaired ability to exhale due to damaged lung and/or airways.
Dr. Sue Ferranti
Internal Medicine 29 years experience
Obstruction...: The prolonged exhalation time is due to the airways obstruction present. An asthma having an acute exacerbation will also have a prolonged exhalation due to the acute airways obstruction present. Once the obstruction is relieved in the asthmatic, the exhalation time will return to normal whereas it won't normalize in the COPD patient since the airways obstruction is chronic.

Narrowed Plumming: Through means we do not completely understand, people with COPD have narrowing of the tubes that deliver air to sacs in the lung where oxygen is absorbed. This is probably due to prolonged exposure to irritants that damage the tissue. The pressure from breathing out can further compress the tubes. The smaller the tube the longer it takes the air to pass.

Lung structuring: As the condition advances, the lungs themselves may change and lose their elasticity. and other structural changes. If this is a problem, you may want to discuss lung rehabilitation with your physician. This may help. Good Luck

It's rough to puff..: It depends on what alternative treatments you're considering. Complimentary treatments such as physical therapy for the lungs, i.e. Pulmonary rehab therapy, with a therapist are known to be effective in improving quality of life. If you're oxygen dependent and want to get rid of oxygen and medications in favor of some alternative you may be risking all the progress you've made to this point.

Yes: Chronic exposure to things that affect the lungs (such as cigarette smoke) could lead to chronic lung scarring. Rates of COPD are higher in those who live in large urban areas due to pollution. COPD can likely be induced in workplace environments.
