Gluten, Genetic Risk Factors, and Lupus

Previous Article Next Article

“Is there gluten in this?” People with celiac disease have 3x the risk of developing lupus, too. But, it can be hard to tell the conditions apart.

Gluten is a group of proteins found in grains such as wheat, rye, spelt, and barley. It acts like a glue and is responsible for the doughy, sticky consistency of bread.

Check out this list from the Celiac Disease Foundation for a list of sources.

For people with celiac disease or non-celiac gluten intolerance, their bodies react to these proteins. Common symptoms include:

  • inflammation
  • digestive problems
  • pain
  • skin problems
  • fatigue

 

People with gluten intolerance and/or celiac disease are more likely to develop or already have other autoimmune diseases. This includes systemic lupus erythematosus (SLE.)

Many people share diet tips online as a way to reduce flares or reduce disease activity. However, there are also many articles on the internet claiming that gluten causes lupus. Most researchers currently consider this to be unlikely and untrue. Though, research that tracks children, including diet, into their adult years is challenging to complete.

A connection to lupus?

Gluten intolerance and celiac disease frequently coexist with lupus. In one survey, the percentage of people with autoimmune diseases and celiac disease was as high as 30% (with the general population having a rate of autoimmune disease ranging from 3-9.4%). However, most scientists do not believe that there is a causal link to lupus. 

Instead, people with these conditions might share genes or gene combinations that make them more susceptible to autoimmune diseases, allergies, and intolerances to otherwise harmless proteins. The length of time that a person is exposed to gluten doesn’t appear to have an effect, which supports this theory. 

A gluten-free diet also did not prevent autoimmune disease in a 2002 study. But, that doesn’t mean that gluten-free diets don’t have value to people with lupus.

 

The benefits of going gluten-free

For people with gluten intolerance or celiacs, gluten can cause flares, worsen symptoms, and trigger the onset of disease. Gluten is also known to affect the microbiome, the colonies of bacteria that call our gut home. This complex network is highly connected to lupus and other autoimmune diseases. Because it does affect these systems, a gluten free diet can potentially help people with lupus who also have gluten intolerances or sensitivities.

Distinguishing lupus from gluten intolerance

Gluten intolerance can have both gut and non-gut-related symptoms. It can even be mistaken for SLE. because the inflammatory markers and symptoms can look almost exactly the same. This makes sense as both are caused by similar immune system issues firmly rooted in genetics.

In fact, this 2004 study provides a case where three different people presented symptoms that were diagnosed as lupus, but were really gluten sensitivity.

So how can you tell the difference?

Going on a gluten-free diet will help with an intolerance, but will have only a limited effect on lupus. Also, if you don’t have gluten intolerance, a restrictive diet won’t help very much with lupus. Figuring out your personal needs and tolerances is key.

Lupus medications will have less of an effect on gluten intolerance because they aren’t treating the core issue. 

Talk to your lupus treatment team if you suspect that you may be intolerant, have lupus, or potentially both. Figuring out what is going on with your body is the first step to finding the medical regimen – and diet – that is best for you.

  1. there is more an more evidence that supports the idea that it is the glyphosates (Round up)that are causing the disruptions in our gut biome which IS our immune systems. The fore creating an array of autoimmune disorders.

    1. I was exposed to RoundUp like crazy while growing up. My father used it like it was water on the lawn and I spent my childhood rolling in it. My mother developed non-Hodgkins lymphoma 2 years ago (and is doing great) and is part of the case against the company. I developed SLE and Sjogren’s 6 years ago. Am I going to be able to be part of the lawsuit against the maker of Roundup?
