Sometimes people with diabetes can suffer damage to the blood supply to their legs. In some cases, the damage is so severe that they need to be amputated. This usually is after the person has had the disease for a significant amount of time, and does not happen to every one with diabetes - only a small percentage. Good control of blood sugar levels, and care of the legs and feet to reduce the chances of restricting circulation or causing injury helps towards keeping limbs healthy.
