Abstract
Background: Diabetes mellitus (DM) is a group of metabolic diseases. It is associated with well-known complications linked to either microangiopathy, macroangiopathy or a combination of both. Some studies found that there were changes in the respiratory system or pulmonary functions in diabetes. Aims and Objectives: This study was planned to see the effect forced expiratory flow (FEF) and peak expiratory flow (PEF) in type 2 DM as pulmonary function tests. Materials and Methods: The present study was undertaken in two groups. Hundred male individuals were included in the study with each group comprised 50 individuals. For pulmonary function tests, we used computerized spirometer statistical difference between the data obtained in various groups was evaluated by z-test. Results: PEF rate reduction and FEF(25–75%) reduction were statistically significant. Conclusion: Hence, it is always better to detect the respiratory damage in diabetes patient at an early stage to prevent further complications
