Your doctor will determine your stage by looking at your symptoms and the results of your breathing tests. The spirometry and pulmonary function test PFT measures your airflow as you inhale and exhale. The PFT will show how much air your lungs can carry. Your doctor will then compare these results to normal results of people with a similar age, height, weight, and ethnic background. Holes in lungs giant bullae : These large holes make it difficult for your lung to expand.
They can also get infected and may lead to a collapsed lung. Collapsed lung: This is a life-threatening condition for people with emphysema because their lungs are already damaged.
Heart problems: Emphysema often increases pressure in the arteries connecting your lungs to your heart. This can cause an area of your heart to expand and then weaken. The outlook for people with emphysema depends on the severity of the condition and how early they start treatment. The earlier you start your treatment, the better your outcome. Lung damage from emphysema is irreversible. But you can slow the progression and improve your quality of life.
This is also known as your forced expiratory volume of air within the first second of forcefully breathing out performed right after breathing in as much air in as possible. You can also use this calculator to get an estimate of your survival rates. People who stop smoking and take steps to protect their lungs from further damage usually have a longer life expectancy. Talk to your doctor about your outlook. Current treatments aim to slow the progression of the disease and reduce symptoms.
Your doctor will recommend a treatment based on the severity and stage of your condition. Your doctor may also recommend therapies to improve breathing and relieve symptoms. For people who need extra oxygen, your doctor may prescribe oxygen therapy. You will use a nasal cannula device or wear a facemask to breathe oxygen through a machine.

Not surprisingly, cigarette smokers are 10 to 15 times more likely to develop emphysema than non-smokers. Emphysema may also be caused by exposure to other pollutants including occupational hazards and exposures such as chemicals and dust, secondhand smoke, poor indoor ventilation and outdoor air pollution.
Some individuals may have a rare genetic deficiency of alpha-1 antitrypsin which is a natural chemical in the body that controls elasticity in the lungs and may protect against damage to the lungs. This deficiency may cause emphysema to develop in non-smokers at a young age, typically under age What are symptoms of emphysema? Emphysema is a serious disease that may be fatal. Detecting emphysema in its early stages may make treating and living with emphysema more manageable.
The symptoms sometimes do not appear right away but rather when the disease is in its later stages typically in smokers after age If any of the symptoms listed above develop, contact a health care provider immediately. The earlier the diagnosis can be made, the easier it will be to manage the disease and benefit from more treatment options. How is emphysema diagnosed? A health care provider may diagnose emphysema by physical exam, history and symptoms. Upon physical exam, a physician may hear wheezing, decreased breath sounds or prolonged exhalation.
But, the gold-standard for diagnosing emphysema is via spirometry which is a lung function test that measures volume and force of air as it is exhaled from the lungs. It measures how much air and how fast the air is exhaled. A chest x-ray or CT scan may show inflated lungs but at the point an x-ray reveals the disease, symptoms are apparent to the patient. X-ray or CT may be helpful in ruling out lung cancer. What kinds of treatment are available for emphysema?
