Studies suggest that those with stage one or two (mild and moderate) COPD who smoke lose a few years of life expectancy at the age of 65. For those with stages three or four (severe and very severe) COPD, they lose from six to nine years of life expectancy due to smoking.
When you have COPD and smoke, your lungs will get damaged more rapidly than if you were to stop smoking. You probably know by now that smoking damages your lungs, raising your risk for bronchitis, emphysema, and lung cancer.
Can you live 10 or 20 years with COPD? The exact length of time you can live with COPD depends on your age, health, and symptoms. Especially if your COPD is diagnosed early, if you have mild stage COPD, and your disease is well managed and controlled, you may be able to live for 10 or even 20 years after diagnosis.
Some people can live with mild or moderate COPD for decades. Other people may be diagnosed with more advanced COPD and progress to very severe disease much faster. Some of this boils down to genetics. But some of it is due to how much you smoke or smoked and the level of lung irritants you are exposed to.
Many people will live into their 70s, 80s, or 90s with COPD.” But that's more likely, he says, if your case is mild and you don't have other health problems like heart disease or diabetes. Some people die earlier as a result of complications like pneumonia or respiratory failure.
COPD is terminal. People with COPD who do not die from another condition will usually die from COPD. Until 2011, the Global Initiative for Obstructive Lung Disease assessed the severity and stage of COPD using only forced expiratory volume in 1 second (FEV1).
Which has worse symptoms? Because emphysema is a late stage of COPD, the signs and symptoms are similar. If you have emphysema, you are already experiencing COPD symptoms, though earlier stages of COPD will not have as dramatic an impact as the degree of tissue degeneration is minimal.
Your physician will determine your stage based on results from a breathing test called a spirometry, which assesses lung function by measuring how much air you can breathe in and out and how quickly and easily you can exhale. They will also consider the severity of your symptoms and the frequency of flare-ups.
By improving your lifestyle, you can live a long and full life with COPD. A common misinterpretation is that 'Chronic' means really bad or extreme rather than long term. Individuals who exercise more and maintain a healthy weight can experience less severe symptoms and enjoy a better quality of life.
Don't spend time around lung irritants.
Since people with COPD have more sensitive lungs, being around any type of irritant can make the condition worse. Avoid things like secondhand smoke, air pollution, dust and fumes from chemicals, paint or cleaning products, as well as mold and mildew.
That's why lung doctors (pulmonologists) say COPD patients should not smoke cigarettes, use e-cigarettes (vaping) or use smokeless tobacco. But even if you are still a smoker, it's not too late to quit – and to reap the health benefits of a smoke-free life.
In general, COPD progresses gradually — symptoms first present as mild to moderate and slowly worsen over time. Often, patients live with mild COPD for several decades before the disease progresses to moderate or severe. However, each patient is unique.
Respiratory failure is considered the major cause of death in advanced COPD.
There is no cure for COPD, but disease management can slow disease progression, relieve symptoms and keep you out of hospital. Treatment aims to prevent further damage, reduce the risk of complications and ease some of the symptoms.
End-stage, or stage IV, COPD is the final stage of chronic obstructive pulmonary disease. Most people reach it after years of living with the disease and the lung damage it causes. As a result, your quality of life is low. You'll have frequent exacerbations, or flares – one of which could be fatal.
All national COPD guidelines should recommend early palliative care. Patients should be referred to palliative care as soon as the patient has intractable breathlessness and/or is presenting more frequently to emergency departments with acute exacerbations.
When COPD gets worse it is called an exacerbation (ex-zass-er-BAY-shun). During an exacerbation you may suddenly feel short of breath, or your cough may get worse. You may also cough up phlegm, and it may be thicker than normal or an unusual color.
Key facts. Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.23 million deaths in 2019. Nearly 90% of COPD deaths in those under 70 years of age occur in low- and middle-income countries (LMIC).
COPD stage 4 life expectancy is 5.8 years. The same study also found that female smokers lost about nine years of their life at this stage.
