Asthma is a chronic airway disease characterized by inflammation and swelling of the walls of your airways, and may be triggered by things that you are allergic to or find irritating. When the airways react, they get narrower, and this causes symptoms like wheezing, coughing, chest tightness, and trouble breathing, especially at night and in the early morning.
Asthma cannot be cured, but most people with asthma can control it so that they have few and infrequent symptoms and can live active lives.

Why is it important to control your asthma?

When your asthma symptoms become worse than usual, it is called an asthma episode or attack. Asthma attacks are not all the same—some are worse than others. In a severe asthma attack, the airways can close so much that not enough oxygen gets to vital organs. This condition is a medical emergency. People can die from severe asthma attacks, even patients with mild or intermittent symptoms at baseline.

So, if you have asthma, you should see your allergy specialist regularly. You will need to learn what things cause your asthma symptoms and how to avoid them. Your allergist will also prescribe medicines to keep your asthma under control.

Taking care of your asthma is an important part of your life. Controlling it means working closely with your doctor to learn what to do, staying away from things that bother your airways, taking medicines as directed by your doctor, and monitoring your asthma so that you can respond quickly to signs of an attack. By controlling your asthma every day, you can prevent serious symptoms and take part in all activities.

If your asthma is not well controlled, you are likely to have symptoms that can make you miss school or work and keep you from doing things you enjoy. Asthma is one of the leading causes of children missing school.
