ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory disease that affects the airways, alveoli, and pulmonary vasculature, leading to irreversible airflow limitation and loss of elastic recoil. This disease is highly prevalent in clinical practice, affecting approximately 10% of adults over 40 years of age, and it is expected to become the third leading cause of death by 2030. The study was conducted on 54 COPD patients diagnosed based on GOLD guidelines. The study observed a statistically significant association between Spirometric staging and the duration of symptoms. The mean value of FEV1/FVC, FEV1 in %, and 6MWD in meters decreased significantly as the grade of GOLD stage increased from stage II to stage III and stage IV. The study showed that COPD is associated with various co- morbidities, including hypertension, diabetes mellitus, hypothyroidism, and coronary artery disease. The study concludes that FEV1, BMI, MMRC grading, and the 6-minute walk test are significant predictors of morbidity among COPD patients. The study recommends early detection and management of COPD to prevent its progression and associated morbidity
