The cause of alcoholic neuropathy is controversial and may be caused by the toxic effect of alcohol on nerve tissue however, it is likely also associated with nutritional deficiencies and may be indistinguishable from nutrition-related neuropathies such as beriberi. The most common symptoms are numbness, tingling, "burning feet", or weakness. However, if severe, it may also affect autonomic nerves (those that regulate internal body functions). Prolonged heavy use of alcohol, or alcoholism that is present for 10 years or more indicates high risk for alcoholic neuropathy.
