The prevalence of diabetes mellitus is on a rising trend. Though great attention has been centered on the chronic complications like retinopathy, nephropathy, neuropathy and the macrovascular complications, the pulmonary complications have been poorly characterised. The aim of the present study was to assess the effects of chronic hyperglycemia on lung function, focusing on mechanical aspects of lung dysfunction with the help of spirometry. These complications might have a significant impact on the quality of life of the patients. This study showed reduced lung function in patients with diabetes, showing a restrictive pattern of lung involvement. Diabetes duration seems a more important influence than the glycaemic control.
