There are two major known causes of emphysema: Smoking. Most of the time, tobacco is the main culprit. Doctors don't know exactly how smoking destroys air sac linings, but studies show that smokers are about six times more likely to develop emphysema than are nonsmokers.
Our estimates indicate that, after 25 years of smoking, at least 25% of smokers without initial disease will have clinically significant COPD and 30–40% will have any COPD.
“With normal aging, lung function declines,” explains Dr. Smith. “And because of that decline, people with smaller airways—who already have low lung function to begin with—may develop COPD later in life. On the other hand, smokers with larger airways might have some reserve to withstand the harmful effects of smoking.
In fact, experts say that it only takes about 100 cigarettes in your life to put you at a considerable risk for COPD. COPD is the 3rd leading cause of death in the United States, so cigarettes are actually responsible for killing more people per year than anything else that can be prevented.
Emphysema is generally caused by cigarette smoking or long-term exposure to certain industrial pollutants or dusts. A small percentage of cases are caused by a familial or genetic disorder, alpha-1-antitrypsin deficiency.
Emphysema and COPD can't be cured, but treatments can help relieve symptoms and slow the progression of the disease.
Prognosis. There is no cure for emphysema. But the condition can be controlled. People with mild emphysema who quit smoking have a normal life expectancy.
There is currently no cure for emphysema. Quitting smoking is an effective way to slow down the progression of the condition.
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.
While lung tissue cells do regenerate, there's no way a smoker can return to having the lungs of a non-smoker. At best, they will carry a few scars from their time smoking, and at worst, they're stuck with certain breathing difficulties for the rest of their lives.
The mystery of why some people appear to have healthy lungs despite a lifetime of smoking has been explained by UK scientists. The analysis of more than 50,000 people showed favourable mutations in people's DNA enhanced lung function and masked the deadly impact of smoking.
People who quit smoking decades ago are still at risk for lung diseases like chronic obstructive pulmonary disease (COPD), according to a study published online Oct.
Since emphysema can't be reversed like other lung conditions, early detection is important. Emphysema symptoms worsen over time, and early detection can slow progression of symptoms and the disease, leading to improved quality of life. It can also help identify causes of the disease so you can limit exposure to them.
You can have emphysema for many years without noticing any signs or symptoms. The main symptom of emphysema is shortness of breath, which usually begins gradually.
"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.
Many people don't notice emphysema symptoms until the disease has destroyed 50% or more of their lung tissue. Until then, the first signs include gradual shortness of breath and tiredness (fatigue). Other emphysema symptoms include: Long-term coughing (smoker's cough).
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.
Take control of your COPD by quitting smoking immediately if you smoke. Also make sure you eat a healthy diet, stay hydrated, get plenty of rest, and pay attention to your body. Stay healthy. Keep your body healthy with smart practices and great hygiene.
About 10 to 15 percent of smokers develop COPD, but the optimal strategy to identify those most at risk is unknown.
How Serious Is Your Emphysema? Stage 1 is also called mild emphysema. But that doesn't mean your disease is mild. You could have significant lung damage before you even notice the breathing problems of stage 1, especially if you're relatively young and otherwise healthy.
In-Home Exercises May Benefit Homebound COPD Patients
A pilot-study of chronic obstructive pulmonary disease (COPD) patients who meet the definition of homebound has found that just two months of aerobic conditioning and functional strength training can produce measurable improvements in quality of life.
Over three million people in the United States have been diagnosed with emphysema. Emphysema is one of the most preventable respiratory illnesses because it is so strongly linked to smoking.
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.
