People with diabetes who have high blood sugar levels are at risk for foot problems. High blood sugar levels:
Foot sores (ulcers) can develop from calluses or blisters caused by friction or rubbing from wearing ill-fitting shoes. Ulcers can also develop from untreated cuts or wounds on the feet.
Foot infections can become severe and travel up the leg and into the bones, which may lead to amputation.
Other foot problems are more common in people with diabetes and can be caused by a breakdown of foot joints and bones (Charcot foot), ill-fitting shoes, or other problems.
Foot problems are usually treated by keeping blood sugar levels in a safe range and by using medications, surgery, and other types of treatment.
All people with diabetes should check their feet regularly for problems. Regular foot exams by health professionals are important as well.
