Are there any foods known to exacerbate restless leg syndrome symptoms?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Some foods can worsen restless leg syndrome (RLS) symptoms. Gluten-containing foods are a common trigger, especially for people with celiac disease or gluten sensitivity, as these conditions can lead to iron and nutrient deficiencies linked to RLS. Other potential dietary triggers include alcohol, caffeine, sugar, and processed foods.

Because RLS can stem from many overlapping causes—nutrient deficiencies, underlying conditions, or medications—identifying your specific triggers matters. A free, instant, online symptom check can help you clarify what's driving your symptoms and guide your next steps, whether that's a dietary change, lab work, or a conversation with your doctor.

Explanation

Restless leg syndrome (RLS) can be uncomfortable and is sometimes linked to what we eat. Gluten, a protein found in wheat, barley, and rye, is one such food that might make RLS worse for some people.

Celiac Disease and RLS: People with celiac disease, a condition where the body reacts badly to gluten, often have RLS. This suggests that gluten might play a role in making symptoms worse.
Gluten-Related Issues: Gluten can cause problems in the nervous system, which might affect how RLS shows up in those who are sensitive to it.

If you think gluten might be a problem for you, use this free symptom checker to help identify potential causes and talk to a doctor about checking for celiac disease. Avoiding gluten could help some people feel better, but it's important to get advice from a healthcare provider before making big changes to your diet.
