CHANGES IN LUNG FUNCTION TESTS IN TYPE -2 DIABETES MELLITUS
Dr. Arati Joshi and Sohail Ahmed*
Background: Type-2 Diabetes mellitus complications are mostly caused by macro vascular and micro vascular damages. Diabetes is a complex medical syndrome comprising of heterogeneous group of disease resulting from diverse aetiologies predominantly of genetic and environmental origin. In type -2 diabeties there is persistent hyperglycemia and abnormal metabolisms of carbohydrate, proteins and lipids. These metabolic disorders result from impaired insulin secretion, altered tissue sensitivity to insulin or coexistence of both. The pulmonary complications of diabetes mellitus have been poorly characterized. The present study has focused on the mechanical aspects of lung dysfunction which are attributable to type 2 Diabetes Mellitus :maximal forced spirometric pulmonary function tests (PFTs) like Forced vital capacity (FVC), Forced Expiratory volume in 1ST sec(FEV1), FEV1/FVC% and peak expiratory flow rate (PEFR), to be specific.
Keywords: Diabetes mellitus, spirometry, FVC, FEV1, FEV1/FVC%, PEFR.
