What happens when you have a diabetic foot wound?

Are at risk: For infection and even gangrene if not properly treated. Cause of wound needs to be determined and proper treatment administered.

Hopefully, not much: Diabetic foot wounds if not healed can lead to life-threatening infections. This can lead to amputation or death as worse case scenarios. Good control of blood sugars, adequate nutrition, good wound care and compliance with doctor's instructions can reduce one's risk of serious complication.

Depends on the care: If the foot ulcer gets severely infected, the infection could spread to bone and could lead to loss of limb or even life. Have the ulcer properly evaluated and treated to avoid preventable complications.
