Vitamin B12 is a crucial nutrient that supports nerve health, red blood cell formation and DNA synthesis. For people living with diabetes, particularly those taking metformin for a prolonged period, monitoring Vitamin B12 levels is vital. This simple blood test helps detect deficiencies early and can prevent serious nerve-related complications such as diabetic neuropathy.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Also known as cobalamin, Vitamin B12 is a water-soluble vitamin naturally found in animal-based foods such as eggs, dairy, poultry, meat, and fish. It is absorbed in the stomach and stored in the liver. A deficiency can develop over time due to:<\/p>

  • Poor dietary intake<\/li>
  • Gastrointestinal absorption issues<\/li>
  • Medication-induced malabsorption (especially metformin)<\/li><\/ul>

    Conversely, low BUN levels may signal malnutrition, liver dysfunction, or overhydration\u2014all of which are relevant concerns in individuals with poorly controlled diabetes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

    • Megaloblastic anaemia<\/li>
    • Aggravation of diabetic peripheral neuropathy<\/li><\/ul>

      Since the symptoms of B12 deficiency overlap with diabetic neuropathy, regular testing is essential to distinguish between the two and initiate the right treatment.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
