why diabetes affects feet
Diabetes also can lower the amount of blood flow in your feet. Not having enough blood flowing to your legs and feet can make it hard for a sore or an infection to heal. Sometimes, a bad infection never heals. The infection might lead to gangrene.
Feet are very sensitive to the effects of diabetes. Potential problems include loss of feeling, diminished blood supply and severe infection that requires amputation. According to the 2011 National Diabetes Fact Sheet, more than 60% of non-traumatic lower-limb amputations occur in people who have diabetes.
