Approximately 80 percent of the patients with mild emphysema lived more than four years after the diagnosis. 60 to 70 percent of patients with moderate emphysema were alive after four years. 50 percent of patients with severe emphysema were alive after four years.What is emphysema life expectancy and which factors affect it?
If the FEV1 is less than 35 percent, emphysema is very severe and it is often predicted that these patients will survive less than four years. Other factors that predict prognosis include the patient's weight (less if lower weight), the distance walked in six minutes, and the degree of shortness of breath with activities.Is emphysema a fatal disease?
Emphysema is a chronic lung disease. That means it can get worse over time, and eventually, one can die from it. Another way to look at it is: emphysema is always fatal if you don't die of something else first, and likewise, emphysema is never fatal if something else kills you first.What does emphysema do to your respiratory system?
Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.
