Can Asthma Be Prevented?

We don't yet know how to prevent asthma, but there are some things that can lower your chances of having an asthma attack.
To prevent asthma symptoms:

• Learn about your asthma and how to control it.

• Avoid things that make your asthma worse as much as possible.
• Get regular checkups from your doctor.
• Follow your asthma self-management plan.
  

Scientists do not yet know how to prevent the inflammation of the airways that leads to asthma. Scientists are exploring some theories:

• Babies exposed to tobacco smoke are more likely to get asthma. If a woman is exposed to tobacco smoke during pregnancy, her baby may also be more likely to get asthma.
• Obesity may be linked to asthma, as well as other health problems.
