One of the many complications of diabetes is amputation of limbs or a part of it like toes or the feet due to diabetic foot ulcers or gangrene. In diabetics numbness in the feet due to diabetic neuropathy (nerve damage) makes them unaware of injuries and foot ulcers. These ulcers sometimes fail to heal which in turn leads to serious infections. Uncontrolled diabetes can cause further damage to the nerves and reduce sensation. When this happens the injuries (even small ones) can keep worsening without any pain and becomes difficult to keep track off. Soon they develop into ulcers infections
