Chronic Obstructive Pulmonary Disease »
What is COPD?
Chronic obstructive pulmonary disease (COPD) is
comprised primarily of two related diseases - chronic bronchitis and emphysema.
In both diseases, there is chronic obstruction of the flow of air through the
airways and out of the lungs, and the obstruction generally is permanent and
progressive over time.
Asthma also is a pulmonary disease in which there is
obstruction to the flow of air out of the lungs, but unlike chronic bronchitis
and emphysema, the
obstruction in asthma usually is reversible. Between "attacks" of asthma the
flow of air through the airways usually is good.
There are exceptions, however. In some patients with
COPD the obstruction can be partially reversed by medications that enlarge or
dilate the airways
(bronchodilators) as with asthma. Conversely, some patients with asthma can
develop permanent airway obstruction if chronic inflammation of the airways leads to scarring and
narrowing of the airway...

I first noticed my PVCs about 7 years ago. I literally thought I was having a heart attack because I had never experienced such a thing before. After a trip to the ER, the doctor told me there was nothing to worry about; however, he did recommend that I change my diet, stress load, etc. I made immediate changes, going from 223 lbs down to 180 lbs through proper diet and exercise. Unfortunately, the PVC's never went away. I experience them frequently; sometimes up to 10 per minute. Although I am hardly aware of them during the course of the day, they often haunt me at night, preventing me from falling asleep immediately. Although I find them to be irritating, I know they're not harmful, which provides some relief. Published: September 17 ::
