Objective: The present study, in patients with type 2 diabetes; It was aimed to analyze fasting blood glucose, insulin and HbA1c values and trace element (zinc, copper, magnesium and chromium) levels.

Material and Method: The study included patients who were 20 patients with type 2 diabetes and 20 healthy controls applied to the Internal Medicine outpatient clinic of Erzurum Regional Training and Research Hospital. The results of the analyzes were calculated with the help of the SPSS (Version 19.0) software package.

Results: Levels of HbA1c, glucose, and insulin in the patient group were significantly higher than in the control group. There was no significant difference among levels of plasma zinc (Zn) and copper (Cu) and erythrocyte Cu in the control group and the patient group. Levels of plasma magnesium (Mg) and chromium (Cr) and erythrocyte Zn, Mg and Cr levels in the control group were significantly higher than in the patient group. Levels of plasma and erythrocyte Mg in people with diabetes were significantly lower than in the control group (p <0.005). The levels of plasma and erythrocyte Cr in the group with type 2 diabetes were significantly lower than in the control group.

Conclusion: To understand the relationship between diabetes and the trace element, well-specified patient samples should be collected. Studies should be carried out using standard methods. More studies should be done to make sense of the changes in trace element levels in diabetes. The necessity of trace element supplementation as a support for treatment should be investigated.
