Diabetes can cause serious foot problems. These conditions include the loss of nerve function (diabetic neuropathy) and loss of circulation (peripheral vascular disease). These two conditions can lead to: 

• Diabetic foot ulcers: wounds that do not heal
• Infections: skin infections (cellulitis), bone infections (osteomyelitis) and pus collections (abscesses)
• Gangrene: dead tissue resulting from complete loss of circulation
• Charcot arthropathy: fractures and dislocations that may result in severe deformities
• Amputation: partial foot, whole foot, or below-knee amputation
