My feet have been getting numb even though I exercise regularly and watch my sugar levels closely. Why?
Foot numbness can be a symptom of peripheral neuropathy. Although diabetes is a common cause of peripheral neuropathy, there are other causes, including low vitamin B12 levels, alcohol use, and thyroid disease. Also, peripheral neuropathy can occur even if there are only mild elevations of blood glucose levels. In addition, peripheral neuropathy can be associated with impaired glucose tolerance (mildly elevated blood glucose levels in the absence of diabetes). You should continue to monitor your blood glucose levels closely as well as continue regular exercise. You should also have a complete evaluation of your foot numbness with your healthcare provider.
