Diabetes and certain other medical conditions that similarly affect the nerves cause special foot care problems that require professional treatment and monitoring. In some people, diabetes will result in nerve damage. When this happens, the nerves go numb and no longer perceive pain, therefore do not warn us of injury.
With diabetes, the body's poor defense against infection and possible damage to blood circulation complicate the problem. Poorly protected from infection by weakened body defenses and loss of circulation, the feet and toes become more vulnerable to injury.
Patients with diabetes must exercise extreme caution, however properly fitting shoes can help protect your feet and avoid injury. Any injury, no matter how minor, deserves careful attention. You also must exercise great caution in trimming toenails, corns, and calluses.
