However, whether you also suffer from chronic bronchitis or not, emphysema can be debilitating. The shortness of breath and low oxygen levels experienced by emphysema sufferers tends to lead to fatigue. Additionally, many of the symptoms are triggered by physical exertion.
Because most patients aren't diagnosed until stage 2 or 3, the prognosis for emphysema is often poor, and the average life expectancy is about five years. Treatment and early detection can play a big part in slowing down the progression of emphysema.
Stage 4 means your emphysema is advanced and that your breathing is very severely affected. At this stage, smoking or other pollutants have destroyed many of the 300 million tiny air sacs, or alveoli, that help bring oxygen into your body and get rid of carbon dioxide.
It takes several years to progress to the final stages of COPD or emphysema, but lifestyle factors play a role. Quitting smoking can significantly improve the outlook. According to the National Heart, Lung, and Blood Institute , COPD can progress quickly in people with alpha-1 antitrypsin deficiency who also smoke.
Emphysema gets worse over time. You cannot undo the damage to your lungs. Over time, you may find that: You get short of breath even when you do things like get dressed or fix a meal.
In certain cases, people with severe emphysema may lose up to 9 years of their life expectancy. Treatment cannot reverse the damage to the lungs, but it can help provide relief and comfort. This article discusses severe emphysema symptoms and how they compare with mild symptoms.
The main symptom of emphysema is shortness of breath, which usually begins gradually. You may start avoiding activities that cause you to be short of breath, so the symptom doesn't become a problem until it starts interfering with daily tasks. Emphysema eventually causes shortness of breath even while you're at rest.
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.
In severe emphysema, sleep is often disturbed and of poor quality, both subjectively and objectively.
"It's not a death sentence by any means. 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.
People with mild emphysema who quit smoking have a normal life expectancy. Those who adopt good health habits can enjoy a fairly normal lifestyle for a long time. Even people whose emphysema is severe have a good chance of surviving for five years or more.
Emphysema continues to progress even after people stop smoking. However, quitting smoking helps reduce symptoms and improve quality of life and life expectancy.
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.
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.
Because emphysema, like other forms of COPD, reduces the amount of oxygen that can reach your bloodstream, the heart works harder to spread oxygen throughout the body. A person with severe emphysema may get tired easily, may have chest pains or palpitations, or experience headaches, sleep problems, and irritability.
Stop smoking
If you smoke, quitting is the single most important thing you can do to improve your health, lung function and slow the progression of your COPD. If you continue to smoke, this will affect your health and respiratory symptoms, so the sooner you quit, the better your chances of living well with COPD.
Many of the symptoms you had in earlier stages, like coughing, mucus, shortness of breath, and tiredness, are likely to get worse. Just breathing takes a lot of effort. You might feel out of breath without doing much of anything. Flare-ups may happen more often, and they tend to be more severe.
It's possible to have emphysema for many years without noticing any symptoms. This is because symptoms usually begin gradually, and we have been designed to have more lung function than we need. Eventually enough of the lung becomes damaged and symptoms will begin to appear.
Life expectancy
A person who receives a diagnosis of stage 4 emphysema can live for a decade or more following the diagnosis. The outlook is typically better for those who quit smoking and manage their symptoms well with medication.
A form of COPD (chronic obstructive pulmonary disease), emphysema develops slowly over time and once it develops, it can't be reversed.
“COPD causes pain because the lungs become blown up like balloons. This causes pressure on the chest wall, the spine, and the diaphragm,” explains Harish Seethamraju, MD, medical director of the lung transplant program at the Methodist J.C. Walter Jr.
Tightness or pain in your chest could be caused by emphysema or heart disease that develops as a result of emphysema. You may notice this more during exercise or when you feel short of breath.
