Prevention of Asthma

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.

Avoid alcohol, tobacco, and marijuana, as all can cause problems. In some cases, these can lead to stillbirth, which is death of the fetus after 20 weeks of pregnancy. In other cases, babies bear long-term effects in the form of fetal alcohol spectrum disorders and asthma.

Preventing allergies from developing

There is no known way to prevent allergies - however, some research has shown that breastfed babies may be less likely to develop allergies and asthma. Children who live in smokefree homes are also less likely to develop asthma.
