Can Eating Gluten-Free Help with Your Eczema Treatment?

Studies find links between celiac disease, gluten sensitivity and eczema

Eczema is an itchy, scaly skin rash that occurs commonly in children but also occurs in adults. When you have eczema, you develop patches of red, cracked skin that sometimes weep clear fluid. The condition, also known as atopic dermatitis, affects 10% to 20% of young children, and about 7% of adults will suffer from a bout of eczema over the course of their lives.

Eczema treatment usually starts with skin creams that contain corticosteroids, which work to calm the inflammation on your skin.

If those don't work, your doctor may prescribe stronger corticosteroids that you would take by mouth. In severe cases, physicians may try other drugs that suppress the immune system reaction that causes the skin inflammation.

However, there may be another alternative for people seeking eczema treatment. The skin condition appears to be linked to celiac disease and to non-celiac gluten sensitivity, and the gluten-free diet (the treatment for both of those conditions) may in fact help treat eczema in some people.

Eczema More Common In Those with Celiac Disease

It's not clear what causes eczema, but the skin condition appears to result from a combination of genetic predisposition and environmental factors.

People with eczema seem to have both lower levels of a type of protein that's associated with a healthy immune system, plus higher levels of a protein that's involved in allergic reactions. Some physicians consider eczema an autoimmune condition, which means it involves your immune system attacking your own healthy tissue by mistake.

Researchers have compared the prevalence of eczema in people who also suffer from celiac disease to eczema prevalence in control subjects, and they've found that eczema occurs about three times more frequently in celiac disease patients and about two times more frequently in relatives of celiac disease patients, potentially indicating a genetic link between the two conditions.

Eczema Also Found in Gluten Sensitivity

Non-celiac gluten sensitivity is not as well understood as celiac disease. However, researchers who are studying it say that symptoms include digestive issues (such as diarrhea, constipation, pain and bloating), plus other symptoms, including brain fog and skin conditions.

Eczema has been associated with gluten sensitivity. Specifically, one 2015 study looked at 17 people with non-celiac gluten sensitivity who had skin problems, including rashes that looked like eczema, dermatitis herpetiformis and psoriasis.

The study found these people's skin improved significantly within about one month when those people adopted the gluten-free diet.

Studies Show Gluten-Free Diet Helpful in Eczema Treatment

It's possible that a strict wheat-free or gluten-free diet could help treat some cases of eczema — both in those with celiac disease patients and in people with gluten sensitivity.

In one study, Finnish researchers looked at candidates for eczema treatment who had suspected wheat allergies but not clinically confirmed celiac disease. Their aim was to identify the specific fraction of wheat causing eczema (which turned out to be gliadin, the toxic protein fragment in celiac disease), but they also found that four of the six adult eczema patients studied successfully treated their eczema by eliminating grains from their diets.

Another (much older) British study looked at the overall prevalence of immune system disorders in patients with celiac disease, and found about 5% of celiac disease patients also had eczema. Two of these patients, out of a total of 17, had "dramatic and persisting relief from their rash when on [the gluten-free] diet," that study reported.

Should Eczema Treatment Involve a Gluten-Free Diet?

In these studies, the gluten-free diet helped some — but not all — eczema patients control their symptoms. So should you consider a gluten-free diet as eczema treatment?

If you've just been diagnosed with celiac disease and you also suffer from eczema, you may find that you resolve some or all of your eczema symptoms with a gluten-free diet.

In addition, since eczema and celiac disease appear to be related genetically, and since both run in families, you may want to consider celiac disease testing if you have eczema and are related to people who have celiac.

If you have eczema along with celiac disease symptoms, you definitely should get tested for celiac disease, since you're already at a higher risk for the condition. Again, if you do turn out to have celiac, you may find as a bonus that the gluten-free diet helps to clear up your eczema symptoms.

Finally, if you've finished with all the medical testing you wish to have for celiac disease (regardless of whether you've been diagnosed with the condition), you might want to consider trying the gluten-free diet on a trial basis for several months to see if it helps with your eczema treatment. Just remember: for the diet to work, you'll need to follow it strictly, without cheating.
