Chronic Obstructive Pulmonary Disease (COPD) refers to a group of lung diseases that obstruct airflow in the lungs. The most common diseases under COPD are Emphysema and chronic bronchitis. It has been noted that most people suffering from COPD have these two lung diseases. The most likely people to contract Chronic Obstructive Pulmonary Disease are smokers–tobacco smokers, but there is a chance of non-smokers to contract it too through constant inhalation of irritating smoke.
It is a disease that develops over a long time, and that is why even former smokers still contract it long after quitting smoking. There is no known cure for Chronic Obstructive Pulmonary Disease, but the available medical treatment for the disease gives a form of relief to the affected person by way of lessening the pain that comes with the disease and symptoms. Some other forms of medical treatment besides medications include surgery and oxygen therapy.
