What is emphysema?

Lung damage: Destruction of lung tissue from exposure to cigarette smoke. As more lung tissue is destroyed, shortness of breath gets worse, and ultimately the lungs cannot do their job, and the body gets starved of oxygen.

COPD: Empysema is a form of copd, chronic obstructive pulmonary disease. It is not curable and it is slowly progressive. There are treatments to control symptoms so you need to see your doctor for both diagnosis and treatment. Smoking cessation is vital to slow progression as well as lessen inflammation and symptoms. You doctor can help with this as well.

Loss of lung tissue: Emphysema is the loss of alveolar units where air exchange takes place in the lung usually secondary to cigarette smoking. In some cases, a genetic deficiency of an enzyme called alpha-1-antitrypsin may be responsible even in non-smokers. The loss of elastic tissue that ensues leads to airflow obstruction and breathlessness especially with exertion.

Emphysema.: Emphysema is a destruction of lung tissue with resultant reduction in oxygen and carbon dioxide exchange and respiratory effort. It's usually due to smoking but could be due to other medial conditions. It's treatable but not curable.
