Diabetic foot ulcers may be neuropathic in origin,
whereby nerve damage resulting from diabetes causes
altered or complete loss of feeling in the foot and/or
leg.
Subsequent trauma may go unnoticed by the
patient and lead to skin loss, blisters and ulcers.
Alternatively, diabetic foot ulcers may be due to
vascular disease, microangiopathy or ischaemic blood
flow which may lead to ulceration and impaired wound
healing.
