what is asthma?

Asthma is a disease that affects your lungs. It is one of the most common long-term diseases of children, but adults have asthma, too. Asthma causes repeated episodes of wheezing, breathlessness, chest tightness, and nighttime or early morning coughing. If you have asthma, you have it all the time.

what causes asthma?

In most cases, we don’t know what causes asthma, and we don’t know how to cure it. You can control your asthma by knowing the warning signs of an attack, staying away from things that trigger an attack, and following the advice of your doctor or other medical professional.

how is asthma diagnosed?

Asthma can be hard to diagnose, especially in children younger than 5 years of age. Regular physical checkups that include checking your lung function and checking for allergies can help your doctor or other medical professional make the right diagnosis.

During a checkup, the doctor or other medical professional will ask you questions about whether you cough a lot, especially at night, and whether your breathing problems are worse after physical activity or during a particular time of year. Doctors will also ask about other symptoms, such as chest tightness, wheezing, and colds that last more than 10 days. They will ask you whether your family members have or have had asthma, allergies, or other breathing problems, and they will ask you questions about your home. The doctor will also ask you about missing school or work and about any trouble you may have doing certain activities.

A lung function test, called spirometry (spy-ROM-e-tree), is another way to diagnose asthma. A spirometer (spy-ROM-e-ter) measures the largest amount of air you can exhale, or breathe out, after taking a very deep breath. The spirometer can measure airflow before and after you use asthma medicine

what is an asthma attack?

An asthma attack happens in your body’s airways, which are the paths that carry air to your lungs. As the air moves through your lungs, the airways become smaller, like the branches of a tree are smaller than the tree trunk. Less air gets in and out of your lungs, and mucus can clog up the airways even more. The attack may include coughing, chest tightness, wheezing, and trouble breathing.

what causes an asthma attack?

An asthma attack can occur when you are exposed to things in the environment, such as house dust mites and tobacco smoke. These are called asthma triggers.

The important thing to remember is that you can control your asthma. With your doctor’s or other medical professional’s help, and an asthma action plan so that you know what to do based on your own symptoms. Decide who should have a copy of your plan and where he or she should keep it. InJAC developed this Asthma Management Plan (also available in Spanish, Karen and Chin) to help Hoosiers manage their asthma. The Asthma Management Plan has been endorsed by the Indiana Department of Education. We invite you to download the document and view the training videos found on our Asthma Resources page.
