Diabetes Mellitus and Serum Vitamin B 12 Concentrations

Abstract

Conclusion

A study of serum vit. B₁₂ concentrations has failed to show significant differences between 333 diabetics and 420 normal persons, between 45 diabetics with and 138 without retinopathy, and only a slight difference between 225 females and 108 males in favor of the females. Within the limits of this study, the serum B₁₂ values of diabetic subjects are the same as those for normal individuals. It is suggested that previously observed differences may reflect vascular damage rather than the diabetic state per se.
