Abstract

Introduction: Type 2 diabetes is the most common metabolic disorder with progressive incidence .Metformin is the first choice treatment in type 2 diabetes. There are evidences that chronic of metformin consumption results in vitamin B12 deficiency, therefore we aimed to evaluate vitamin B12 levels in diabetic patients with and without metformin usage. Methods: Overall,90 type 2 diabetic patients were selected. A questionnaire containing personal information and duration of diabetes and drug information was completed.Laboratory tests including CBC, FBS, HbA1C and vitamin B12 levels were measured. Serum vitamin B 12 below 200 pg / ml was considered as low. Patients divided into two groups with and without metformin taking and all variables compared between these two groups. Results: Mean age of patients was 52.5 ± 5.72 years .76, patients were consumed metformin and 14 patients didn’t take it. The mean duration of metformin using was 4.95 ± 4.57 years. The prevalence of vitamin B12 deficiency in all patients was 73.3. Vitamin B12 level in metformin users was 159.7±132.5 pg/ml and in non - metformin users was125.4±116.2 (p=0.79). There was no significant difference between two groups regarding to B12 level and MCV. There was not any significant difference in dosage (p=0.80) and duration (p=0.63) of metformin treatment between patients with and without B12 deficiency. Also there was no statistically significant difference in other parameters in B12 deficient patients and others. Conclusion: Vitamin B12 deficiency was common in our diabetic patients but there was no relation between metformin consumption and serum vitamin B12 concentration.
