COPD
Chronic
Obstructive Pulmonary Disease
is a progressive disease that causes airflow blockage and problems related to
breathing. It can cause coughing
that produces large amounts of a slimy substance called mucus, wheezing,
shortness of breath as well as chest tightness. Cigarette smoking
is the leading cause of COPD. Long-term exposure to various lung irritants such
as air pollution, chemical fumes, or dusts also contribute to COPD. A rare
genetic condition called alpha-1 antitrypsin (AAT) deficiency can also lead to
COPD. COPD cannot be cured but it can be treated to lower the chance of
complications, and generally improve quality of life. Clinical symptoms and
signs, such as abnormal shortness of breath and increased forced expiratory
time, can be used to help with the diagnosis of COPD. Various forms of
treatment include Medications, supplemental oxygen therapy
and surgery.
