A Study on Vitamin B12 Deficiency in Non-Vegetarian Diabetic Patients on Long-Term Metformin Therapy at a Tertiary Care Centre

Abstract

Background: Type 2 Diabetes Mellitus (T2DM) is a prevalent chronic disease worldwide, and Metformin is one of the most commonly prescribed oral anti-diabetic drugs. While Metformin is effective, long-term usage is associated with Vitamin B12 deficiency, potentially leading to complications like neuropathy. Studies from India, especially among non-vegetarian populations, are limited.
