ToggleGluten and Skin Allergies: The Bottom Line
Gluten is well-known for causing celiac disease, but can gluten cause other skin problems? Evidence that connects gluten to many other abnormalities and diseases keeps piling up. And these conditions include those that affect your skin. For some, gluten causes the immune system to overreact. It causes inflammation. And it can lead to a variety of allergic and immune type reactions. Since these are also underlying factors of many skin conditions, it’s not surprising that the connection is strong. So let’s start by taking a closer look at some of the skin conditions triggered by gluten. Prefer to learn by video? Here’s my breakdown below:Dermatitis Herpetiformis
Dermatitis herpetiformis (DH) is a rash defined by clusters of itchy bumps and blisters. And science tells us it’s a common skin manifestation of celiac disease, meaning it’s directly caused by gluten. Most experts argue that a DH diagnosis is enough to confirm celiac disease.
Chronic Urticaria Celiac Disease & Gluten
Another gluten allergy on the skin is Urticaria, also known as hives. It is a common skin condition affecting 15 – 25% of people within their lifetime. It produces itchy pink or red bumps as well as patches of swelling. Chronic urticaria (CU) is less common (0.5 – 1% of the population), but more debilitating since it lasts more than 6 weeks. In 30 – 50% of cases, CU is believed to be caused by an autoimmune response, which helps explain its connection to celiac disease as well as many other autoimmune conditions. In a large population study, it was reported that celiac patients were 1.5 times more likely to develop urticaria and almost 2 times more likely to develop CU than the general population. In this study, celiac disease was found in 5% of children with CU but only 0.67% of children without CU. The children diagnosed with celiac disease were placed on a gluten-free diet. Within 5 to 10 weeks, all cases of CU went into full remission. Based on these findings, evidence suggests some cases of CU may also be a skin manifestation of celiac disease.Psoriasis & Gluten

Eczema – Strong Links to Celiac

Rosacea & Your Gut Microbiome
Rosacea is an inflammatory skin condition that causes patches of red skin on the face. While it has been observed in men, it’s more common among women. Rosacea shares genes that are associated with other autoimmune conditions, such as celiac disease. Plus, women with rosacea are 2 times more likely to develop celiac disease than the general population. And those with celiac disease are almost 1.5 times more likely to develop rosacea. Other gastrointestinal conditions have also been linked to rosacea, including gut bacteria imbalances. Researchers hypothesize that an overgrowth of pathogenic bacteria may activate specific proteins in the blood that promote inflammation and lead to flushing in the face. This may help explain why antibiotics have been successfully used to treat flare-ups. Thus, it’s important to mention that numerous studies have determined that people with celiac disease tend to have gut bacteria imbalances, including more pathogenic gut bacteria than healthy subjects. Plus, in this animal study, gluten-containing diets reduced the diversity of bacteria in the gut. When the animals were then put on a gluten-free diet, the diversity improved. And diversity is one of the most important factors when it comes to a healthy gut microbiome. Learn more about curing your rashes caused by gluten here!Vitiligo, Autoimmunity, & Gluten


Acne, Gluten, and Diet
In this article, I discuss numerous ways in which gluten contributes to the development of acne. And there’s evidence suggesting that a gluten-free diet may help clear up your skin. In one case study, a woman was battling severe acne. She tried antibiotics and topical treatments as well as a steroid medication. The steroid medication provided some relief, but she started experiencing unpleasant side effects, such as anxiety and blood sugar imbalances. This woman was also given proton pump inhibitors for acid reflux, experienced prolonged menstrual cycles, and took an iron supplement for anemia. All red flags for celiac disease. And testing confirmed a vitamin D deficiency and the presence of anti-gluten antibodies. Her doctor recommended a gluten-free diet and vitamin D supplementation. At first, she didn’t experience any relief from her acne. But her acid reflux disappeared. So she kept with the diet. After 3 months, her acne started to clear. Within 8 months, her skin was completely healed except for a few lingering scars. A similar case was also reported of a man with chronic acne, food allergies, and digestive discomfort. Antibiotics were prescribed for his acne with no success. Lab tests revealed the presence of anti-gluten antibodies. A gluten-free diet and vitamin D supplementation were prescribed. Within 4 months the pimples on his chest, back, and arms were completely gone. Plus, he reported that his stomach felt “normal” again.Gluten-Induced Malabsorption and Nutrient Deficiencies
Because of the damage gluten causes to the lining of the small intestine, malabsorption and nutrient deficiencies are common among those with gluten sensitivity. This is relevant because nutrient deficiencies can negatively affect your skin. I already mentioned the link between psoriasis and vitamin D deficiency. Below are some other connections between specific nutrient deficiencies and skin conditions.Zinc & Skin Problems
Zinc deficiency is believed to cause acquired acrodermatitis enteropathica, which looks a lot like eczema. However, diarrhea and hair loss (a.k.a. alopecia) are also common symptoms. Zinc deficiency is also associated with slow wound healing, weeping eczema (eczema with pus-filled blisters), and acne.Iron & Skin Problems
A lack of iron can cause dry, itchy skin as well as angular stomatitis, which causes red and swollen patches in the corners of your mouth.Vitamin B12 and Folate
Vitamin B12 and folate deficiencies are also associated with angular stomatitis as well as hyperpigmentation, which causes darker patches of skin. A lack of vitamin B12 is also associated with vitiligo.Vitamin A & The Skin
Vitamin A deficiencies can cause an excess of the protein keratin to be produced in your skin, which can clog your pores and sweat glands.Vitamin C
Scurvy is a disease caused by a vitamin C deficiency and the symptoms include scaly, dry skin as well as easy bruising and slow wound healing.Vitamin B3
A lack of vitamin B3 can cause skin inflammation, a condition known as pellagra.Antioxidant Vitamins and Minerals
It’s important to note that vitamins A, C, and E as well as zinc and selenium act as potent antioxidants. This means they play an important role in protecting your skin from free radical damage. Thus, deficiencies can affect the health of your skin.
Excess Carbs and Skin Disease
Most gluten-containing foods are packed with quickly digested starch and sugar. So when consumed regularly in excess, it increases your risk for many diseases. These include obesity, insulin resistance, and type 2 diabetes. Some skin diseases associated with these conditions include:- Acanthosis nigricans (darker patches in skin folds and creases)
- Skin tags
- Keratosis pilaris (a.k.a. chicken skin)
- Plantar hyperkeratosis (corns and calluses)
- Bacteria and yeast infections
- Striae distensae (a.k.a. stretch marks)
Gluten Induced Kidney Damage Can Cause Skin Disease
In this article, I discuss how gluten can lead to kidney disease. And there are several skin conditions associated with kidney disease, which include:- Dry skin
- Nephrogenic systemic fibrosis (thickening and darkening of the skin)
- Acquired perforating dermatosis (discolored, raised circular patches of skin surrounding hair follicles)
- Non-melanoma skin cancer
Concerns with Conventional Treatments
When a skin condition arises, most people schedule an appointment with a dermatologist. And more often than not, oral and topical medications are prescribed. For example, steroid medications are commonly used to reduce skin inflammation. However, they only mask the symptoms. They don’t address the underlying problem. So as soon as you stop taking them, your symptoms will return. Plus, steroids are not safe to take long term. Potential side effects of topical steroid medications include:- Skin thinning and discoloration
- Ridge marks
- Rosacea
- Perioral dermatitis (a rash that occurs around the mouth)
- Acne
- Purpura (a.k.a. blood spots)
- Suppression of the immune system
- High blood sugar and type 2 diabetes
- Water retention and swelling
- Calcium deficiency

Firstly I’d like thank you for this article, I’ve been looking for some confirmation between face redness and gluten sensitivity. I’ve never been diagnosed with celiac and never thought I’m sensitive. I’ve developed over the last 9 years redness on my skin and bumpy texture on my chin. It all started with my chin becoming red and getting the texture, and last three years redness moved to my chicks, and nose areas. I’m also mostly plant-based for the last 9 years, but I had a journey of eating eggs, baked products containing milk and eggs, and 2 years ago I started eating meat as strongly believed that my low iron and hair loss caused by lack of meat. After some time of eating meat my face symptoms worsened, my chin and nose area started patching, flaring red and very itchy. I stopped eating meat completely and after a month worsening symptoms disappeared. But bumpy texture and still redness stayed. I’ve been using niacinamide by The Ordinary for my nose to keep it less red, it helped with nose but not with the other areas of my face. About a month ago I was told by my cosmetologist that I most likely have gluten sensitivity cause of my skin. It made me double think as I knew about connection of iron absorption and gluten, so I’ve decided to try gluten free seriously. One month after my redness on chicks and nose area has disappeared 👻 and even bumpy texture on my chin is getting flattened. Two days ago I accidentally had a little piece of gluten with my dinner (I first tried food and then checked its label) and I felt cramps in my stomach and diarrhoea for all evening. That’s when I found the diarrhoea is a symptom of gluten sensitivity and I’ve been struggling with it for the last three years. I’m very determined now to continue with gluten free diet and looking forward to see more of improvements.
I’ve been following no grain no pain for almost four years.
I still however experience itchy face and dry itchy nose. I also have eczema patches on my forehead, eyebrows, scalp, and sides of my face. I wonder what else could be causing it. I also have a few small eczema patches on my elbows and knees.
You might consider investigating for the following:
1. Other food sensitivities
2. Nutritional deficiencies
3. The possibility of mold exposure
4. Yeast overgrowth in your intestines (mimics gluten exposure)
Do you have any information about Pyroderma Gangrenosum? My 78 yr old sister has it and it is very painful. Took years to be diagnosed. She is waiting for some kind of injection but meanwhile do you think it would help her to try a gluten free diet. I am 71 and have celiac. She is my only sister. Thank you.
Thank you so much for this amazing article.
Both my sons had super red reactive skin. Every mosquito bite swelled and turned bright red. They had daily rashes, itching, and swelling until we removed gluten and dairy. Now they both have perfectly clear skin .
Thank you for educating more people on the side effects of gluten. I believe people need to know they consume gluten at their own Risk.
So glad the diet change is helping you and your family! Thanks for sharing your Thanks for sharing your story!! Your positive experience might help someone else who is struggling! #payitforward #Save100MillionLives
Thank you so much Dr. My son was practically failure to thrive. He was 2.5 years old losing weight, barely growing and unable to learn to speak. He was in the 4th percentile since shortly after birth. He was utterly in agony from constant stomach pain. His skin was itchy, red and swelling. He was utterly miserable until I prayed for wisdom. In a last ditch effort, I took gluten and dairy out of his diet together and in just a very short time his skin cleared, his stomach pain cleared up, he started growing, gaining weight and started talking. Thank you so much for getting this information out it really does save lives.
