Diabetes mellitus and lung function tests

Objective: To measure the effects of type 1 and type 2 diabetes mellitus on the various spirometric pulmonary function tests Methods: This study involved 70 diabetic patients, 25 type 1 and 45 type 2 diabetes mellitus, and 45 control group. Type 1 diabetic patients included 14 males and 11 females, their ages ranging from 1763 years with their mean was 47.12, with SD12.83. Type 2 diabetic patients included 26 males and 19 females; their ages ranging from 19-63 years with their mean 46.67, with SD 9.50. The control group involved 24 males and 21 females, their ages ranging from 13-68 years with their mean 38.78, with SD13.3. The study was conducted in Ibn Sena Teaching Hospital Medical Outpatient Clinic, Al-wafa Medical Center in Mosul, and Mosul University-Medical Center. Results: There were statistically significant differences between the control group and type 1 diabetes mellitus during the measurements of FVC%, FEV1/FVC% and MMFR%, with statistically significant reductions in their values when compared to controls. Furthermore, type 2 diabetes mellitus has significant effects on FVC%, FEV1 and FEV1/FVC% when compared with the controls, with statistically significant differences from the control group. There were no much differences between them apart from the FVC% which favors type 1 diabetes mellitus over type 2 diabetes mellitus with highly significant P-value. Conclusion: The present study clearly indicates that both type 1 and type 2 diabetes mellitus adversely affects the various pulmonary function tests, and the results are in accord with other previous studies.
