Assessment of COPD burden through its stages

The study included 300 patients with COPD who are current smokers. Overall, 98% of them were males, and all were older than 40 years. Patients were classified into three groups: mild, moderate, and severe. Amount of cigarettes was found to be directly proportionate to COPD burden. Regarding weight burden, obesity wasn’t found to be a sign of increasing burden of the disease, while cachexia was found in the more severe COPD stage. We found that dyspnea and other symptoms of the disease were found to be increased with increased disease severity indicating more health burden with the more severe COPD stages. Also ,Mental health status had a direct positive correlation with COPD severity.
