Abstract

Background: Vitamin B12 deficiency often leads to hematological and neuropsychiatric disorders. Vitamin B12 deficiency usually begins with megaloblastic anemia. Neurological symptoms often occur later.
Case Report: We describe a case of 55-years old type 2 diabetic male patient with rare cause of bilateral vocal fold paralysis due to vitamin B 12 deficiency. He was under treatment of insulin, metformin and valsartan for 5 years.
Conclusion: Physcians should be kept in mind that long term use of metformin could result vitamin B12 deficiency when assesing the etiology of focal fold paralysis. We tried to discuss the recovering case after vitamin B12 treatment in the context of the literature.
