Asthma Triggers

Tuesday, September 20, 2011

People who have asthma are sensitive to triggers, things that can set off a reaction in your lungs. These triggers can be found indoors or out. Dr. Edward Hill tells us more about asthma triggers in todays 60 Second Housecall.

Dr. Hill:

Asthma is the most common serious chronic medical condition of children and the number one cause of hospital admissions of children under 15 years of age.

Asthma is not something that children outgrow. Childhood asthma persists into adulthood for 72 percent of men and 85 percent of women.

No one really knows the causes of asthma. What we do know is that asthma is a chronic inflammatory disease of the airways. An asthma attack develops when certain asthma triggers are present.

The causes of asthma symptoms can vary for different people. Still, one thing is consistent with asthma: when airways come into contact with an asthma trigger, the airways become inflamed, narrow and fill with mucus.

Triggers for an acute asthma attack include:

- colds or respiratory infections

- exposure to cigarette, pipe or cigar smoke

- allergic reactions to substances such as pollen, food, animal dander or dust

- air pollution, either indoors or outdoors

- exercise

- sudden cold air exposure, and

- excitement or stress
