The causes are probably different for different types of diabetic neuropathy. Researchers are studying how prolonged exposure to high blood glucose causes nerve damage. Nerve damage is likely due to a combination of factors:

* metabolic factors, such as high blood glucose, long duration of diabetes, abnormal blood fat levels, and possibly low levels of insulin
* neurovascular factors, leading to damage to the blood vessels that carry oxygen and nutrients to nerves
* autoimmune factors that cause inflammation in nerves
* mechanical injury to nerves, such as carpal tunnel syndrome
* inherited traits that increase susceptibility to nerve disease
* lifestyle factors, such as smoking or alcohol use
