Asthma

What is Asthma?

Asthma is an inflammatory condition of the airways.  When you have asthma, your airways tend to swell and the muscles around your airways tighten.  All of this causes your airways to narrow and slow down the air you are trying to exhale.  When you can’t exhale completely, air gets trapped in your lungs making it difficult to inhale deeply.

What are symptoms of Asthma?

Coughing, wheezing, chest tightness or pressure, and shortness of breath are all common symptoms of asthma.  However, symptoms can vary from person to person.  Most do not have all these symptoms at the same time and their symptoms will be different for each asthma attack.

Will I always have asthma symptoms?

People with asthma can lead active lives.  You can participate in sports, attend school and avoid hospital stays and emergency room visits with proper asthma management.  Most people go extended periods of time without any symptoms then have episodes of acute worsening, called asthma attacks.

How can I control my asthma?

Visit your doctor regularly and if your doctor gives you an asthma action plan follow it closely.  When possible avoid triggers that may cause you to have an asthma attack.  Most importantly, watch for early warning signs that an asthma attack may be on the way and act quickly to stop it.

What are asthma triggers?

These are things outside the body which cause your airways to become swollen and tightened.  Triggers are different for every person.  Therefore, the first step to preventing asthma episodes is knowing your asthma triggers and finding ways to avoid them.
