How can we help?
Asthma is a long-term (chronic) disease of the lungs that causes a person’s airways to become inflamed. This inflammation can make breathing difficult for three reasons:
When you breathe, you breathe in oxygen from the air. You also get rid of carbon dioxide when you breathe out, a gas that’s produced when your body’s cells use up oxygen. This exchange takes place in your lungs, two sponge-like organs in your chest. Here’s how it works:
With your inflamed airways narrowed by swelling, tightening, and mucus, air doesn’t move as easily into and out of your lungs. It can be like trying to breathe through a narrow straw — you have to work extra hard to get air in and out. When you have other asthma symptoms, like coughing, wheezing, and chest tightness, and shortness of breath, you’re having an asthma flare-up or asthma “attack."
Since asthma interferes with your breathing, it’s a serious condition. Uncontrolled asthma causes people to miss work or school, go to the hospital, or even die. Fortunately, people can learn to control their asthma and avoid serious problems.
See a doctor if you notice any of the symptoms of asthma. It’s important to diagnose and treat asthma so you can control it before it becomes life threatening.
See your doctor if your asthma treatment isn’t working and you need to use your quick-relief medicine more than 2 times a week for an asthma flare.
Call 911 right away if you or your child has life-threatening symptoms of an asthma flare-up.
Researchers don’t know for sure what causes asthma. They think it is probably caused by a combination of genetics (what you inherit from your family) and your environment (the places you live, learn, work, or play).
However, doctors and researchers do have a good understanding of what causes asthma to flare up. If you have asthma, your inflamed airways are “twitchy”— they overreact to irritants in your environment. These irritants are called triggers, and they include anything that sets off an asthma flare-up. Different people have different triggers. Some common asthma triggers are allergies, chest colds, pollution, viral or bacterial infections, and exercise. To control your asthma, you have to find out what your triggers are and learn how to deal with them.
Although anyone can get asthma at any age, but certain risk factors can increase your changes of having it:
Here’s what your doctor may do to gather information before an asthma diagnosis:
Treatment of asthma involves avoiding your triggers, taking medicine, and making sure you respond to your asthma symptoms when you notice them. Your doctor will create an Asthma Action Plan, a treatment plan that will help you prevent symptoms and respond when you have an asthma flare-up.
There are two basic types of asthma medicines:
Instead of being controlled by your asthma symptoms, you can begin to take charge of your health by controlling your asthma. Work with your asthma care team to:
While you may not be able to prevent having asthma, you can control your asthma and prevent flare-ups. Follow your Asthma Action Plan and avoid your triggers to prevent an asthma flare-up.
