What Happens During an Asthma Attack?

Tuesday, April 20th, 2010

People with asthma have acute episodes when the air passages in their lungs become narrower, and breathing becomes more difficult. This is due to increased sensitivity of the lungs and airways. The lungs and airways overreact to certain triggers and become inflamed and clogged. Breathing becomes harder and may hurt. There may be coughing.

May be a wheezing or whistling sound, which is typical of asthma. Wheezing occurs for the following reasons:
* The muscles surrounding the airways tighten and the lining of the airways swells and pushes inward.
* The membranes that line the airways secrete extra mucus than normal.
* The mucus can form plugs that further block the air passage.
* The air, passing through the narrowed airways produces the wheezing sounds.
