How does alcohol affect multiple sclerosis?
The relationship between alcohol and MS is complex and research shows mixed results. Here's what we know:
Effects on MS Symptoms:
For some people, alcohol may temporarily reduce MS symptoms by modulating immune cell activity. However, heavy or long-term alcohol use can weaken the immune system and potentially worsen MS-related inflammation.
Alcohol's effects on the central nervous system—like impaired coordination or slurred speech—can mirror or worsen existing MS symptoms. If you already struggle with balance, speech, cognition, or bladder control, alcohol may make these issues more noticeable while drinking.
A MyMSTeam member shared: "I was having a good day until I had an alcoholic beverage, and then came pain 30 minutes later."
Effects on Disease Progression:
Studies suggest moderate to high alcohol consumption may be associated with more severe brain lesions on MRI and could negatively affect disability progression, though results vary. Some research indicates moderate red wine consumption might be linked to lower disability scores, but more studies are needed.
Interactions with Medications:
Most disease-modifying therapies don't have strict alcohol restrictions, but side effects may be stronger when drinking. One member noted: "I've just noticed my tolerance is almost nonexistent. One glass of wine, and I'm floored."
Always discuss your drinking habits with your neurologist to understand how alcohol specifically affects your MS and medications.
