Emphysema Symptoms, Causes and Diagnosis

The main reason for the person to have Emphysema is smoking heavily for ages. People who suffer from this disease may smoke for some time but do it regularly. Tabacco, as well as some other factors, possess special airborne irritants, and some people cannot withstand them. Marijuana, air pollution, and chemical fumes may be the causes too. Rarely, the patient may simply lack protein to defend the lungs.
