Question: I am diabetic, and I work very hard at keeping it under control. I have aches in my feet occasionally and magnetic insoles have been a blessing. Is this safe?

Dr. Hibberd's Answer:

Diabetes mellitus is a chronic disease characterized by abnormally high levels of sugar glucose in the blood. It often affects the capillaries, which in turn, affect nerve function. Sensory nerve damage or neuropathies (usually an initial loss of sensation to light touch), are commonly seen in the hands and feet and need aggressive management in an attempt to reduce progression.

Aches in your feet do not necessarily reflect neuropathy or circulation issues, but do deserve evaluation. Local causes of discomfort also need attention. Foot care in diabetes is of paramount importance, and you are correct in your concern. The insoles sound like they are helpful for you, but studies of magnetic insoles have not demonstrated any significant benefit when placed under rigorous trial circumstances. Nonetheless, never argue with success, and continue with your insoles. Also, have your feet examined for causes of foot discomfort. Be sure your sensation is tested with a monofilament which is a great screen for sensory neuropathy changes.

Meticulous control of your diabetes will decrease the incidence of complications, improve circulation and help delay neuropathy. The hemoglobin A1c (a blood test) is the best indicator for measuring your degree of glucose control, and is recommended to be checked periodically or at least twice yearly in addition to meticulous control of your blood lipids to decrease your vascular risks.
