Abstract

Background: Hypomagnesemia (serum magnesium level < 1.7 mg/dl) occurs more frequently in patients with type 2 diabetes mellitus (T2DM).Serum magnesium levels are not routinely tested in hospitalized patients, including in hospitalized patients with T2DM. Objectives: To evaluate the prevalence of hypomagnesemia among hospitalized T2DM patients treated with proton pump inhibitors (PPIs) and/or diuretics. Methods: A total of 263 T2DM patients hospitalized in general departments were included in the study and were further divided into four groups: group 1 (patients not treated with PPIs or diuretics), group 2 (patients treated with PPIs), group 3 (patients treated with diuretics), and group 4 (patients treated with both PPIs and diuretics). Blood and urine samples were taken during the first 24 hours of admission. Electrocardiogram was performed on admission. Results: Of the 263 T2DM patients, 58 (22.1%) had hypomagnesemia (serum magnesium level < 1.7 mg/dl). Patients in group 2 had the lowest mean serum magnesium level (1.79 mg/dl ± 0.27). Relatively more patients with hypomagnesemia were found in group 2 compared to the other groups, although a statistically significant difference was not observed. Significantly more patients in group 3 and 4 had chronic renal failure. Patients with hypomagnesemia had significantly lower serum calcium levels. Conclusions: Hospitalized T2DM patients under PPI therapy are at risk for hypomagnesemia and hypocalcemia.
