Objective: The aim of this study was to evaluate the effects of different intervals of the self-monitoring of blood glucose (SMBG) on glycemic control in a selected type 2 diabetic population. Methods: Type 2 diabetic patients with disease duration >1 year who were on insulin treatment for at least 6 months and were already applying SMBG were included in the study. A total of 118 patients were enrolled and classified into groups based on SMBG frequencies as once in a week, once in two weeks, once in a month and not at all. At the end of the 12 weeks glycemic control was assessed with measured blood glucose and A1c levels. Results: After 3 months of monitorization, A1c levels significantly decreased in group 1 (p<0.005) and group 2 patients (p<0.05) and no change or even an increase was observed in other groups. Reported hypoglycemic events were rare in all patients. Conclusion: SMBG is important for the achievement of glycemic goals and simplifying SMBG may help to overcome problems of compliance and cost
