What is Diabetic Neuropathy?

Diabetic neuropathy is nerve damage that can occur in people with diabetes. It is a common complication of diabetes and can be serious. Diabetics have a higher risk for peripheral neuropathies due to nerves being damaged by high blood glucose levels and high levels of fats.  In addition, Metformin (the first-line drug of choice for type II diabetes) can cause B12 deficiency. Studies and case reports suggest that 10% - 30% of patients who take Metformin have reduced vitamin B12 absorption,2,3 and severity worsens with length of use.

Symptoms of diabetic neuropathy generally affect the legs and feet and can more rarely affect hands and arms. Symptoms include:

  • Tingling
  • Numbness – which can become permanent
  • Burning sensation – which may increase in the evening
  • Increase sensitivity to touch
  • Pain

Symptoms usually develop gradually. However, some people may not notice an issue until considerable nerve damage has been done.

Studies and case reports suggest 10% - 30% of patients who take matformin have reduced vitamin B12 absorption.

60-70% of Diabetic patients will experience some form of Neuropathy.1
