What causes alcoholic neuropathy?

Scientists aren’t certain exactly what causes alcoholic neuropathy, but one theory is that long-term alcohol abuse has a toxic effect on the nervous system.  Over time, alcoholics often develop vitamin B12 deficiency that, together with poisoning from alcohol, results in severe irreparable nerve damage, including the destruction of nerve cells.

B12 and Alcohol Consumption

About half of all long-time alcoholics suffer from nerve damage and vitamin B12 deficiency, affecting the central nervous system and peripheral nerves, including the autonomic nervous system that controls internal bodily functions.

Symptoms of alcoholic neuropathy

The earliest symptoms of nerve damage from vitamin B12 deficiency are easily overlooked, especially where alcoholism is a factor. If you feel like you’re always tired and depressed, or have trouble thinking clearly, then that could indicate the onset of neuropathy.  In alcoholics, it’s easy to see how depression can be written off as another result of excess alcohol use.

Treatment options

Where alcoholism is the cause of vitamin B12 deficiency, only cessation of alcohol abuse can result in a lifelong cure.

If you are experiencing any of the above-mentioned symptoms, it’s imperative that you request a vitamin B12 blood test from your doctor. While the results aren’t always reliable (they only count total vitamin B12 levels, not active vitamin B12), they can indicate the need for vitamin B12 supplementation.  Overall, your symptoms are the best gauges for deciding how much vitamin B12 you need, and for how long.

If diagnosed with vitamin B12 deficiency, your doctor will prescribe routine vitamin B12 shots (taken intramuscularly), to be followed by long-term vitamin B12 supplements.

Other coping mechanisms for alcoholic neuropathy may include:

•Physical therapy

•Shin splints

•Orthopedic inserts

•Diabetic socks

•Pain relief medication



•Blood pressure medication
