November 20, 2024, marks the 23rd World COPD Day, with this year's theme, Know Your Lung Function. Lung function testing is a key method for diagnosing chronic obstructive pulmonary disease (COPD) and plays a crucial role in its early detection and prevention.

Chronic obstructive pulmonary disease (COPD) is a persistent lung condition resulting from lung damage. This damage leads to inflammation, or swelling and irritation, within the airways, restricting airflow in and out of the lungs—referred to as obstruction. Common symptoms include difficulty breathing, a daily mucus-producing cough, and a tight, whistling sound known as wheezing.

COPD is primarily caused by prolonged exposure to irritants such as smoke, fumes, dust, or chemicals, with cigarette smoke being the leading cause.

The two main forms of COPD are emphysema and chronic bronchitis, which often occur together but can vary in severity among individuals. Chronic bronchitis involves inflammation of the bronchi, the tubes that carry air into the lungs. This inflammation hinders airflow and results in excessive mucus production. In emphysema, the tiny air sacs in the lungs, called alveoli, are damaged, reducing their ability to transfer oxygen to the bloodstream.

Although COPD tends to worsen over time, it is manageable. With effective treatment, many people with COPD can control their symptoms, enhance their quality of life, and reduce the risk of complications like heart disease and lung cancer.
