This hospital-based, comparative, descriptive study examined the relationship between several indicators and the altering pattern of blood magnesium levels in Type 2 diabetes mellitus (T2DM). The study involved 100 people in total (50 cases and 50 controls). In comparison to controls, the diabetic group had considerably lower mean serum magnesium levels. Among diabetic individuals, a sizeable percentage had hypomagnesemia. A correlation between blood magnesium levels and the duration of diabetes, glycemic control, and diabetic retinopathy was found in the study. The cross-sectional design and the study's single hospital location are its drawbacks, though. To confirm the results and investigate the function of magnesium in the treatment of T2DM, more study is required. [ABSTRACT FROM AUTHOR]
