Vitamin deficiency in Diabetes #bestcardiologistinperambur #bestcardiologistinkolathur#angiokolathur

Vitamin B12 deficiency is prevalent in Diabetic patients especially in those who use metformin in the long term.

Metformin interferes with B12 absorption, leading to deficiencies that can exacerbate peripheral neuropathy (nerve damage). Routine screening is advised for patients taking long-term or high-dose metformin

Key Connections Between B12 and Diabetes
  • Metformin Link: Long-term use of metformin (more than 2g/day) is a leading cause of low B12 in diabetics.
  • Neuropathy Misdiagnosis: Both diabetes and B12 deficiency cause peripheral neuropathy, including numbness, tingling, and pain. A B12 deficiency can make these nerve issues worse.
  • Symptoms: Fatigue, memory issues, numbness/tingling in hands and feet, and anemia are common signs of deficiency.
  • Recommendations: The American Diabetes Association and other groups suggest checking B12 levels periodically in metformin users, particularly if they have neuropathy or anemia
Management
  • Supplementation: If a deficiency is confirmed, vitamin B12 supplementation (such as oral tablets or, in severe cases, injections) is generally required.
  • Diet: Including B12-rich foods (meat, dairy, fortified foods) is essential, although supplements are often necessary to correct a significant deficiency
