How Can Asthma Be Prevented?

You can’t prevent asthma. However, you can take steps to control the disease and prevent its symptoms. For example:

  • Learn about your asthma and ways to control it.
  • Follow your written asthma action plan. (For a sample plan, go to the National Heart, Lung, and Blood Institute's "Asthma Action Plan.")
  • Use medicines as your doctor prescribes.
  • Identify and try to avoid things that make your asthma worse (asthma triggers). However, one trigger you should not avoid is physical activity. Physical activity is an important part of a healthy lifestyle. Talk with your doctor about medicines that can help you stay active.
  • Keep track of your asthma symptoms and level of control.
  • Get regular checkups for your asthma.
