COPD: Prevent Exacerbations

Medically reviewed by Last updated on Jun 5, 2024.


An exacerbation of COPD

means your symptoms get much worse very quickly and can become life-threatening. Exacerbations can be triggered by infections such as a cold or the flu. Lung irritants such as air pollution, dust, fumes, or smoke can also be triggers.

Go to pulmonary rehabilitation (rehab) if directed:

Rehab is a program run by specialists who help you learn to manage COPD. Examples include a pulmonologist (lung specialist), dietitian, or exercise therapist. The specialists will help you make a plan to avoid triggers that cause an exacerbation.

Protect yourself from germs:

Germs can get into your lungs and cause an infection. An infection in your lungs can create more mucus and make it harder to breathe. An infection can also create swelling in your airway and prevent air from getting in. You can decrease your risk for infection by doing the following:

Do not smoke:

Nicotine and other chemicals in cigarettes and cigars can cause lung damage and make your COPD worse. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.

Avoid secondhand smoke:

This is smoke another person exhales. Even if you have never smoked or have quit, it is important to avoid secondhand smoke. This smoke can also cause lung damage or trigger an exacerbation.

Use pursed-lip breathing any time you feel short of breath:

Take your medicines as directed:

Your healthcare provider may prescribe medicine to help you breathe easier. It is important that you take your medicines as directed to prevent or stop an exacerbation. Refill your medicines before you are out so that you do not miss a dose. Talk to your healthcare provider or pharmacist if you have any questions about how to take your medicines.

Avoid anything that makes your symptoms worse:

Stay out of high altitudes and places with high humidity. Stay inside, or cover your mouth and nose with a scarf when you are outside in cold weather. Stay inside on days when air pollution or pollen counts are high. Do not use aerosol sprays, such as deodorant, bug spray, and hairspray.

Exercise daily:

Exercise for at least 20 minutes each day to help increase your energy and decrease shortness of breath. Talk to your healthcare provider about the best exercise plan for you.

Walking for Exercise

Drink liquids as directed:

You may need to drink more liquid than usual. Liquid will help to keep your air passages moist and help you cough up mucus. Ask how much liquid to drink each day and which liquids are best for you.

Follow up with your doctor as directed:

You may need more tests. Your doctor may refer you to a specialist, depending on your needs. Some specialist services may be available through your pulmonary rehab program. Write down your questions so you remember to ask them during your visits.
