COPD (Chronic Obstructive Pulmonary Disease) is a prevalent and significant health issue worldwide. It is a chronic respiratory condition characterized by persistent airflow limitation and difficulty in breathing. COPD encompasses chronic bronchitis and emphysema, often caused by long-term exposure to harmful particles or gases, primarily from tobacco smoke.
The prevalence of COPD varies across different countries and populations. According to the World Health Organization (WHO), COPD affects more than 251 million people globally. It is estimated that 3.17 million deaths occur each year due to COPD, accounting for approximately 5% of all deaths worldwide.
While COPD is more common in older individuals, it is not solely an age-related disease. Risk factors such as smoking, exposure to indoor and outdoor air pollution, occupational hazards, and genetic predisposition contribute to its development. The burden of COPD is expected to increase in the coming years due to aging populations and continued exposure to risk factors.
Early diagnosis, proper management, and lifestyle modifications can help improve the quality of life for individuals with COPD. It is crucial to raise awareness about COPD, promote smoking cessation programs, and implement measures to reduce exposure to environmental pollutants to mitigate the impact of this prevalent respiratory condition.
