There are many things people at risk for COPD can do:
If you smoke, the best thing you can to do prevent more damage to your lungs is to quit. To help you quit, there are many online resources and several new aids available from your doctor. The National Cancer Institute has information on smoking cessation. Visit SmokeFree.gov, the American Lung Association, or call 1-800-QUIT NOW for more information.
Try to stay away from other things that could irritate your lungs, like dust and strong fumes. Stay indoors when the outside air quality is poor. You should also stay away from places where there might be cigarette smoke.
See your doctor regularly even if you are feeling fine. Make a list of your breathing symptoms and think about any activities that you can no longer do because of shortness of breath. Be sure to bring a list of all the medicines you are taking to each doctor's visit.
Do your best to avoid crowds during flu season. It is also a good idea to get a flu shot every year, since the flu can cause serious problems for people with COPD. You should also ask your doctor about the pneumonia vaccine.
