Correlation between Serum Magnesium Levels and HbA1C in Type 2 Diabetes Mellitus

Abstract

Background and Objective: Type 2 Diabetes Mellitus is a chronic disease resulting from acomplex inheritance, environmental interaction along with risk factors such as obesity andsedentary life style. Magnesium has been stated to have potential role in improving insulinsensitivity and preventing diabetes related complications. Hypomagnesaemia is proposed as oneof the factor in the pathogenesis of diabetic complications. The aim of our study is to estimatethe correlation between serum Magnesium levels and the level of Glycemic control (HbA1c) inpatients with Type 2 Diabetes Mellitus.Methods: This is an observational study conducted in SVRRGGH and SVMC, Tirupati, AndhraPradesh which included 94 patients with type 2 Diabetes mellitus of more than 5 years duration.These patients were divided into 2 groups based on level of Diabetic control. Group A included30 patients with HbA1c below 7.0mg/dL (good glycemic control) and Group B included 64patients with HbA1c above 7.0mg/dL (poor glycemic control). In both the groups SerumMagnesium levels were estimated.Results: Mean Serum Magnesium levels in Group A was 2.280±0.3955mg/dL while in Group Bit was 2.087±0.5834 mg/dL with a p-value 0.0379 (<0.05) which is statistically significant. Inour study though the mean values of serum Magnesium are within normal reference range, meanvalues of serum Magnesium levels in patients with poor glycemic control(HbA1c>7.0) arestatistically low as compared to patients with good glycemic control (HbA1c <7.0).Discussion: It has been reported that Serum Magnesium levels are lower in uncontrolleddiabetics when compared to controlled diabetics and also serum magnesium levels vary withtreatment for diabetes. In our study, although the mean values of serum magnesium in bothgroups are within Normal reference range (1.7-2.2mg/dL), they are statistically low in groupwith poor glycemic control (HbA1c >7.0mg/dL) when to group with good glycemic control(HbA1c< 7.0mg/dL).Thus this gives an insight into the association of hypomagnesaemia andlevel of diabetic control.Conclusion: This effective comparative study of deals with varying Magnesium levels inspecific diabetic therapies and analysed the effect of urinary magnesium detected inHypermagnesuria with Magnesium supplementation.
