Understanding Chronic Obstructive Pulmonary Disease (COPD)

Chronic Obstructive Pulmonary Disease (COPD) is a persistent lung disorder marked by airflow restriction, abnormal lung inflammation, and excess mucus secretion. This obstruction hinders proper airflow, impairing oxygen intake. Common symptoms encompass a chronic cough and difficulty breathing.
The disease includes two prevalent types: emphysema, which involves enlarged air sacs and air trapping, and chronic bronchitis, characterized by a continual cough and mucus overproduction.

According to health data, around 34 million Americans are affected by COPD.

COPD is the third leading cause of mortality in the United States, primarily impacting middle-aged and older populations. Smoking is the primary risk factor, with nearly 50% of smokers showing early lung alterations and about 25% developing COPD after prolonged smoking. Exposure to secondhand smoke also increases risk. Quitting smoking significantly lowers the likelihood of developing the disease.

Globally, COPD ranks as the third leading cause of death, claiming around 3 million lives annually. Many individuals remain unaware they have the condition.
