Short answer

**Alcoholic neuropathy happens when long-term heavy drinking damages your nerves, likely through alcohol's direct effects and poor nutrition.**

The exact mechanism is not fully understood. Heavy drinking can interfere with how your body uses and stores nutrients, including vitamin B1, also called thiamine. You may notice gradually worsening tingling, burning, numbness, or weakness in both legs. Regular meals and treatment for vitamin deficiencies support your care, but stopping alcohol is central to preventing further damage. If you are dependent on alcohol, get medical help before stopping because sudden withdrawal can cause seizures.

Common questions

Why does Alcoholic neuropathy happen?

Alcoholic neuropathy is nerve damage linked to long-term heavy drinking. Alcohol likely injures nerves directly, while poor nutrition and difficulty using vitamins such as thiamine contribute. The exact mechanism is not fully understood. Symptoms usually develop gradually in both legs and can include burning, numbness, or weakness. See a clinician to check for vitamin deficiencies and other causes, including diabetes. Stopping alcohol and correcting deficiencies help prevent worsening, but damage can persist. If you are dependent on alcohol, get medical help before stopping to manage withdrawal safely.
