What is CLRD?
Chronic Lower Respiratory Disease (CLRD) is a severe illness affecting millions of people. It is currently the fourth leading cause of death in the United States and is projected to move into third place nationwide by 2021. However, mortality rates for the top two leading causes of death in the state and nation are heart disease and cancer, respectively, are decreasing, deaths from CLRD continue to rise.
CLRD comprises three significant diseases, i.e., chronic bronchitis, emphysema, and asthma. Their main characteristic is shortness of breath caused by airway obstruction, which is irreversible in chronic bronchitis and emphysema but is reversible in asthma. CLRD was previously referred to as Chronic Obstructive Pulmonary Disease (COPD), according to the International Classification of Diseases, as used by the World Health Organization (WHO). This classification was revised in 1999, and the classification refers to COPD as chronic bronchitis and emphysema only, and CLRD is used to refer to chronic bronchitis, emphysema, and asthma.
The leading cause of CLRD is cigarette smoking, which accounts for about 80% of cases. In addition to this, the exposure to air pollutants at home, workplace, respiratory infections, and genetic factors also play a significant role in developing the chronic lower respiratory disease as cited by the Centers for Disease Control and Prevention (CDC).
