Celiac disease, gluten sensitivity and skin issues canker sores in the mouth

If you have dermatitis herpetiformis, you’re considered to also have celiac as long as your celiac blood tests also are positive. Although your physician can prescribe the medication dapsone to temporarily subdue the rash and its itching, the gluten-free diet represents the only long-term treatment for dermatitis herpetiformis.​ Psoriasis and Celiac Disease

Several studies show that the skin condition psoriasis, which causes thick, scaly red plaques to develop on your skin, shares a strong link with gluten consumption. Psoriasis patients often have high levels of antibodies to gluten circulating in their bloodstreams, which indicates that they’re reacting to gluten in their diets even if they haven’t been diagnosed with celiac disease.

It’s not clear whether the gluten is causing psoriasis, or if psoriasis patients also have higher rates of celiac disease — more research is needed to determine the cause and effect.

However, some anecdotal reports indicate that psoriasis patients can see their skin symptoms improve dramatically when they adopt a gluten-free diet, regardless of whether they’ve been diagnosed with celiac disease. Eczema and Celiac Disease

Eczema occurs most often in children, but adults also can suffer from the skin condition. Although the primary treatment for eczema is topical corticosteroids, there’s some evidence that for some people, eczema may be linked to celiac disease. For these people, a gluten-free diet may help to treat the skin condition. Alopecia Areata and Celiac Disease

Alopecia areata, an autoimmune condition in which your body attacks your hair follicles and causes your hair to fall out, also has been linked in research studies to celiac disease. Again, the link between the two conditions isn’t clear and could reflect a higher incidence of celiac in people with alopecia areata, as opposed to a cause-and-effect relationship for gluten in their diets.

Most of the research that shows a link also reports that people with both celiac and alopecia areata found their hair grew back when they adopted a gluten-free diet, but some non-celiacs with alopecia areata also experience seemingly random hair regrowth. Chronic Urticaria (Hives) and Celiac Disease

A 2005 study found that 5% of children with chronic urticaria — or hives — also had celiac disease. Once the children in the study were diagnosed with celiac disease and adopted the gluten-free diet, all saw their chronic urticaria disappear within five to 10 weeks. Acne and Celiac Disease

Although there’s no published medical research showing a link between celiac disease or gluten sensitivity and the common teenage skin condition acne, many acne sufferers have reported relief from their skin condition when they went gluten-free. However, if the acne sufferers adopted a low-carb diet in addition to a diet devoid of gluten, it’s possible that caused the acne improvement since low-carb diets have been shown to clear pimples. Keratosis Pilaris (Chicken Skin) and Celiac Disease

Again, while there’s no research that links celiac with keratosis pilaris, a skin condition that causes tiny goosebump-like bumps to form, mainly on the backs of your upper arms, many people report that the condition disappears once they adopt a gluten-free diet. Keratosis pilaris is more common in those with eczema and seems to run in families. Dry Skin and Celiac Disease

Many people with celiac disease and gluten sensitivity suffer from very dry skin, and in some cases, this clears up after they adopt a gluten-free diet. Again, it’s not clear whether the condition causes the dry skin, but some physicians have suggested that the malabsorption associated with the untreated celiac disease can rob your skin of needed nutrients.
