Abstract: Diabetes mellitus (DM) is a group of metabolic diseases characterized by hyperglycaemia resulting from defects in insulin secretion, insulin action, or both. It is associated with increased oxidative stress. This study evaluates the levels of the antioxidant enzymes superoxide dismutase (SOD) and gluthathione peroxidase (GPx), as a measure of antioxidant status in Type 2 diabetics. A total of 182 subjects were involved in the study, of which 109 were diabetics (Test) and 73 non-diabetics (Controls). The criterion for the classification as a diabetic was based on subjects having glycated haemoglobin (HbA1c) levels 6.5 %. A structured interviewer administered questionnaire was used as an aid in the collection of demographic and lifestyle data from the subjects. HbA1c was estimated quantitatively by immunochemical method. SOD and GPx was measured by the sandwich-enzyme linked immunosorbent assay (ELISA) method. Glucose oxidase method was used for the determination of fasting plasma glucose (FPG). Mean SOD and GPx values in the diabetic subjects were significantly lower (p
