Why does Alcoholic neuropathy happen?
Last updated September 7, 2026.
**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.
What to do
- **Get evaluated:** Arrange a clinician visit for persistent tingling, numbness, or weakness.
- **Plan safe withdrawal:** If you shake or sweat when you skip alcohol, seek medical help before stopping.
- **Discuss nutrition:** Ask your clinician whether you need vitamin testing or prescribed supplements.
- **Protect your feet:** Check your feet daily for cuts or blisters if sensation is reduced.
