Why does diabetes cause foot ulcers?

The biggest reason for diabetic foot ulcers is that the patients often have neuropathy. They don’t feel pain and can be totally unaware of the wound developing on the bottom of the foot. Once the wound develops, infection can set in. Very often they also have diminished blood supply and a weakened immune response. Unfortunately they have all strikes against them and these wounds can lead to amputation. However, with treatment, foot ulcers can heal.
