Abstract

Background: Diabetes and poor glycaemic control alters the metabolism of magnesium (Mg) by increasing their urinary excretion and lowering serum Mg levels. Low serum Mg levels will contribute to the evolution of diabetic complications such as retinopathy, abnormal platelet function, cardiovascular disease and hypertension via reduction in the rate of inositol transport and subsequent intracellular depletion. This study aimed at evaluation of serum Mg levels with Type 2 diabetics and control non diabetic individuals.Methods:  After the Ethical approval, blood samples from recruited subjects (50 diabetics and 50 non diabetics) were collected and estimation of Mg in serum by xylidyl blue method, Fasting blood sugar (FBS) and post prandial blood sugar (PPBS) by Glucose oxidase peroxidase (GOD-PAP) method was done. Descriptive statistics mean and standard deviation, independent sample ’t’ test, level of significance 5% were used for analysis.Result:  Mean value of FBS in control group of 100.98mg/dL and in case group with 134.80mg/dL. Mean value of PPBS in control group of 108.76mg/dL and in case group with 236.6mg/dL. Mean value of serum Mg in control group was 1.64mmol/L while in case group=1.20mmol/L. Serum magnesium was significantly decreased (p<0.001) in diabetics than controls. A negative linear relationship (p<0.05) between, Mg and FBS (r=-0.198 and p=0.048), Mg and PPBS (r=-0.206 and p=0.040) was found.Conclusion: The present findings demonstrate the imbalance in levels of serum Mg among the patients of type 2 DM in comparison to controls.  Since serum magnesium is easily and inexpensively measured, and as oral magnesium replacement is cheap and safe, there is an argument for screening of diabetic patients for hypomagnesaemia and institution of supplementation if it is detected.
