COPD: Avoiding Your Triggers

What is an Actionset?

You can do things at home to manage COPD (chronic obstructive pulmonary disease). By learning the triggers for COPD and avoiding them, you can help reduce flare-ups. While some triggers may be out of your control, there are others you can easily avoid.

Key points

  • Learn and avoid the common triggers for COPD.
  • By avoiding flare-ups, you may feel better, be more active, and reduce the impact of COPD on your life.
  • Pay attention to symptoms that may warn you of a flare-up. You may need to see your doctor or go to the hospital if your symptoms are severe.

Return to topic:

A trigger is anything that causes your COPD symptoms to flare up or get worse. Triggers include:

  • Illnesses like colds, the flu, acute bronchitis, or pneumonia.
  • Poor air quality, such as indoor and outdoor air pollution, smoke, or smog.
  • Tobacco smoke.
  • Cleaning supplies or other chemicals.
  • Gases, particles, or fumes from wood or kerosene home heaters.
  • Not taking or running out of your medicines.
  • Things you are allergic to, such as:
    • Pollen, mold, or dust mites.
    • Pet hair, skin, or saliva.

Not all people have the same triggers. What may cause a flare-up in one person may not be a problem for another person.

Test Your Knowledge

Getting sick with the flu can trigger a flare-up of COPD symptoms.


Flare-ups of COPD symptoms are caused by the same things for everyone.


Flare-ups of COPD can greatly limit your activities. You may even need to stay in the hospital. By avoiding flare-ups, you may feel better, be more active, and reduce the impact of COPD on your life.

So it is important to pay attention to your symptoms. You can tell you're having a flare-up when your usual symptoms suddenly get worse. For example:

  • You may wheeze or be more short of breath than usual.
  • You may cough more than usual. Your cough may or may not bring up mucus. Or you may notice a change in the color or amount of mucus you cough up.
  • You may have a fever, have trouble sleeping, or feel very tired. Or you may feel depressed or confused.

With treatment, many people are able to breathe as well as they did before a flare-up.
