Emphysema

Emphysema Introduction:

Emphysema is a pathological diagnosis and means when translated from the original Greek word "swelling of a body part". What is swollen is the alveolus (= air sac) in the lung where the air exchange takes place. Due to a loss of elastic tissue the air sacs melt into larger ones until eventually they form big balloon like structures (called "bullae").

This leads to a problem with breathing the air out as with chronic lung disease the lungs have become stiff without the normal elasticity and the air gets trapped. Ephysema is part of the clinical picture of chronic obstructive pulmonary disease (COPD). Another condition, chronic bronchitis, is also part of the COPD complex, all of which is often found simultaneously in the same patient in different parts of the lungs.

Here is a link to a site which summarizes this with some illustrations. Occasionally severe end stage asthma can also lead to emphysema.

Emphysema symptom:

The hallmark of emphysema is shortness of breath and a chronic cough. The term "pink puffer" has been coined to describe the usually pink skin colour due to open skin vessels (from carbon dioxide retention in the blood stream) and difficulties catching a breath. This site gives you a lot more information that may be of interest.

Diagnostic tests:

The testing is the same as for COPD. As emphysema is a chronic lung illness that requires a close follow-up and a lot of attention to detail, it is advisable to seek a referral from your general practitioner to a lung specialist (respirologist or pulmonologist). From the multitude of diagnostic tests the specialist will choose the ones that are most appropriate for a given patient.

Emphysema treatment:

For smokers this link, which shows the importance of quitting smoking, may convince you to follow through. Self hypnosis cassettes or discs can be very useful in assisting you to quit smoking. There is a subgroup of patients with alpha-1 PI deficiency who will benefit from Alpha1-Protease Inhibitor Augmentation Therapy.

Otherwise the treatment for emphysema and COPD are identical.
