Diabetic neuropathy.

Diabetic neuropathy, the most common peripheral neuropathy in the Western world, is responsible for most limb amputations and considerable morbidity in diabetic patients. Although it is a sequela to insulin deficiency and/or hyperglycemia, its exact pathogenetic mechanism remains unclear. Therapy is directed at early diagnosis, exclusion of other neuropathic disorders, prudent glucose control, and avoidance of secondary complications of neuropathy such as foot ulceration by aggressive foot care, hygiene, and patient education.
