How is lung capacity affected in people with asthma?

Your question:  How is a person's lung capacity affected if a person suffers from asthma?

My answer:  If you have well controlled asthma your lung function should be relatively normal between attacks.  The way to develop well controlled asthma is to see your doctor on a regular basis, take your asthma medications exactly as prescribed. There are about 10-20% of asthmatics who may develop severe asthma, and this may be due to repeated uncontrolled asthma exacerbations or by other things, such as smoking cigarettes, that cause lung scarring, or chronic airway changes, withing the lungs.  These severe asthmatics may develop some degree of permanent loss of lung capacity.  Otherwise, the only time your lung capacity will be diminished is while you are having an asthma attack.
