Numbness of the feet, also known as peripheral neuropathy, is a common complication of diabetes. Diabetes is a chronic condition that affects how the body processes glucose, which can lead to high blood sugar levels. Over time, high blood sugar levels can damage the nerves in the body, particularly those in the feet and legs.

Symptoms of numbness in the feet caused by diabetes can include tingling, burning, or stabbing sensations in the feet, as well as a loss of feeling in the feet. These symptoms can be mild or severe and may worsen over time.

Numbness of the feet caused by diabetes is thought to be related to a combination of factors, including:

  1. Peripheral neuropathy – elevated blood sugar levels can damage the small blood vessels that supply oxygen and nutrients to the nerves, leading to nerve damage
  2. Reduced blood flow – diabetes can also damage the blood vessels that supply oxygen and nutrients to the tissues causing disturbed sensation and pain
  3. Nerve compression – diabetes can be complicated by entrapped nerves in legs and feet. The most common examples are the tibial nerve in the tarsal tunnel and the peroneal nerve in the peroneal tunnel

Preventing or managing numbness in the feet caused by diabetes requires:

  1. Good blood sugar control – this can be achieved through a combination of medication, dietary changes and exercise
  2. Taking good care of the feet – this includes keeping the feet clean and dry, wearing comfortable and well-fitting shoes and avoiding going barefoot
  3. Quitting smoking – smoking can damage the blood vessels that supply oxygen and nutrients to the nerves, worsening peripheral neuropathy
  4. Getting regular feet check-ups – people with diabetes should have regular foot exams to check for signs of neuropathy or other foot-related complications
  5. Medication – certain medications, such as antidepressants or anticonvulsants, may be prescribed to help manage the symptoms of neuropathy
  6. Surgery for entrapped nerves – this can be effective to improve sensation, reduce pain and prevent complications from the neuropathy, such as diabetic foot ulcers

If you are experiencing numbness in your feet or other symptoms of peripheral neuropathy caused by diabetes, it is important to discuss your symptoms with your healthcare provider. With proper management and care, it is possible to prevent or manage neuropathy and maintain good foot health.
