Almost two-thirds of people with diabetes suffer from mild to severe nerve damage. The result is diminished feeling in the feet. You may not feel cuts, scratches and blisters in the skin of your feet. These wounds can become infected. In addition, your blood nourishes tissues and carries infection-fighting cells to those tissues that need them.
Diabetes can cause circulation problems – your feet may suffer from a reduced blood supply, putting you at greater risk for infection and even amputation.
