To study the haemoglobin levels in patients with hypomagnesemia suffering from type 2 diabetes mellitus.

Objective: To study the association of anemia with serum magnesium levels in diabetic type 2 patients. Study Design: Cross Sectional Retrospective study. Setting: Department of Physiology of Sindh University Jamshoro in collaboration with the Diabetic OPD of Liaquat University Hospital Hyderabad. Period: January 2022 to June 2022. Methods: The data size comprised 300 patients suffering from diabetes mellitus type 2. They were divided into two groups. The control group comprised of 160 type 2 DM patients with normal serum magnesium levels and the test group comprised of 140 patients with decreased serum magnesium levels. The serum magnesium level was determined by Roche C311 auto analyzer while the hemoglobin level was measured by Sahli’s hemoglobinometer. Results: Type 2 Diabetic patients with normal serum magnesium level shows 18.75% decrease haemoglobin level while Type 2 Diabetic patients with hypomagnesemia showed 32.15% decrease in haemoglobin level. The P value was 0.01. The odds ratio was 2.05. Conclusion: Diabetes mellitus leads to hypomagnesemia and Hypomagnesia produces anemia due to hemolysis.
