Abstract:
Chronic obstructive pulmonary disease (COPD) affects about 300 million people worldwide, resulting in approximately 64 million disability-adjusted life years. Household air pollution affects almost 3 billion people worldwide and is a major risk factor for COPD. An estimated 25% to 45% of patients with COPD worldwide have never smoked. Fourteen percent of the overall COPD burden is attributable to occupational exposures. Rural populations are at higher risk for COPD than urban residents. African American never-smokers have a disproportionately high prevalence and Hispanic people have a low prevalence of COPD.

01:22Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
