Impact of Diabetes Mellitus on Pulmonary functions in COPD patients

Abstract Introduction COPD is known to be a multisystemic inflammatory disease that goes beyond lung involvement. The association of decreased lung functions and diabetes mellitus has been studied for many years suggesting that the lung could be a target organ in diabetes mellitus. Objective assessment of pulmonary functions in COPD patients with normoglycemia and with diabetes mellitus, and patients with diabetes mellitus. Patients and Methods The study was conducted in Ain shams university hospitals After the inclusion criteria was met, patients were divided into 3 groups, each group was 20 patients,(group 1): diabetes mellitus patients,(group 2): COPD patients, and (group 3): COPD with diabetes mellitus patients. spirometry was performed and results were analyzed. Results In COPD with diabetes mellitus patients (group 3), the lung functions were the least. Diabetes mellitus was also an independent risk factor for reduced lung functions as was seen in nonsmoking diabetic patients (group 1). Conclusion Pulmonary functions are reduced in DM independent of smoking.
