Quitting Smoking

If you’re currently a smoker, the most important thing you can do to slow the progression of your COPD is to quit smoking now! Smoking can cause your COPD to worsen more quickly than if you were to stop smoking. It’s also important for your environment to be smoke-free. This means you should avoid being in the company of other people who smoke.


As we age, even healthy lungs lose some function. Smokers who get COPD lose lung function at a much faster rate. People who have frequent flare-ups (red line) lose lung function faster, too.

Quitting smoking is the most important thing you can do to actually slow down the loss of lung function. While you cannot return lung function to normal after quitting smoking, you will slow the progression of your COPD. If you have already quit smoking, congratulations!

How Smoking Affects Your Lungs

"Susceptible Smokers" are individuals whose lungs are significantly damaged by smoking and develop COPD. Their lung function starts to go down at a very early age. Even at ages 35 to 45, lung function begins to decline and this group will start to have symptoms of COPD like chronic cough or mild shortness of breath with heavy work or exercise. These early signs of COPD are often ignored because they are mild. If this age group stops smoking, they may avoid developing significant COPD.

Some people in the “Susceptible smokers” group have a severe decline in lung function because of multiple hits. These include smoking, breathing hazards in the air, other medical problems or Alpha-1 Antitrypsin Deficiency (genetic COPD) (al-fa-one an-tee-trip-sin dee-fi-shin-see). Frequent flare-ups / exacerbations also cause a faster rate of lung function loss.These individuals have severe disease earlier in life.

Not taking care of COPD often leads to multiple exacerbations and a faster decline in lung function in the last couple years of life.
