Abstract

A series of lung conditions known as copd cause airflow obstruction and make breathing challenging. COPD is most frequently caused by chronic bronchitis and emphysema. The effects of COPD on the lungs cannot be undone.Shortness of breath, wheezing, or a persistent cough are symptoms. Rescue inhalers, oral or inhaled steroids, andother treatments can help manage symptoms and limit future harm. The most common chronic cause of diseaseand mortality in the world is COPD. Very few researches have examined its incidence, despite the fact that itsprevalence is already well-documented. In order to better understand COPD in the general population, we looked into its prevalence, incidence, and lifetime risk.
