Understanding Dermatitis Herpetiformis and Its Symptoms

You may have heard of dermatitis herpetiformis, a skin condition that can cause itchy blisters to develop on your skin. These blisters can be a sign of an autoimmune disorder that’s related to gluten sensitivity. People with celiac disease or gluten intolerance are at higher risk of developing dermatitis herpetiformis, but it can also affect people who do not have these conditions.

The symptoms of dermatitis herpetiformis include small, raised, and itchy blisters that typically appear on the arms, knees, and buttocks. The rash can be chronic or intermittent and may be red, brown, or purple in color. Some people may also experience burning, stinging, or itching sensations on their skin.

If you notice these symptoms, it’s important to see a dermatologist or allergist as soon as possible. A professional will be able to provide a proper diagnosis and recommend appropriate treatment options.

Causes and Triggers of Dermatitis Herpetiformis

If you have been diagnosed with Dermatitis Herpetiformis, you may be wondering what causes this autoimmune disorder. The truth is that the exact cause of Dermatitis Herpetiformis is not fully known, but it is believed to be closely linked to gluten sensitivity and celiac disease.

Gluten sensitivity is an immune reaction to gluten, a protein found in wheat, barley, and rye. Celiac disease, on the other hand, is an autoimmune disorder that affects the small intestine, triggered by the consumption of gluten. While not all people with Dermatitis Herpetiformis have celiac disease, studies suggest that up to 80% of those with Dermatitis Herpetiformis also have gluten sensitivity.

Factors that may trigger Dermatitis Herpetiformis outbreaks include:
Consuming gluten: As mentioned, gluten sensitivity and celiac disease are closely linked to Dermatitis Herpetiformis. Consuming gluten-containing food or products can trigger an outbreak of itchy blisters.
Stress: Stress can trigger or worsen a Dermatitis Herpetiformis outbreak. It is important to manage stress levels and practice relaxation techniques such as yoga, meditation, or deep breathing.
Medications: Certain medications, particularly those containing iodine, may trigger an outbreak of Dermatitis Herpetiformis.

While gluten sensitivity is a major factor in Dermatitis Herpetiformis, it is worth noting that not all people with gluten sensitivity will develop this skin condition. It is important to work with a healthcare provider or a dermatologist to properly diagnose and treat Dermatitis Herpetiformis.

Treatment Options for Dermatitis Herpetiformis

If you have been diagnosed with dermatitis herpetiformis, there are several treatment options available to help manage your symptoms and improve your skin health. It is important to work closely with your healthcare provider to determine the most suitable approach for you.

Adhere to a Gluten-Free Diet

One of the most effective ways to manage dermatitis herpetiformis is to eliminate gluten from your diet. This involves avoiding foods that contain wheat, rye, and barley, as well as other gluten-containing ingredients such as malt and brewer’s yeast. It may also be necessary to avoid certain processed foods, as they may contain hidden sources of gluten. By adhering to a gluten-free diet, you can help reduce inflammation and improve the overall health of your skin.

Utilize Medication

In addition to a gluten-free diet, your doctor may recommend medication to help manage your symptoms. Dapsone is a commonly prescribed medication that can help reduce inflammation and relieve itching. Other medications, such as sulfapyridine and colchicine, may also be used in some cases. It is important to discuss the potential benefits and risks of medication with your healthcare provider before beginning treatment.

Implement Proper Skin Care Practices

In addition to dietary changes and medication, proper skin care practices can also help alleviate symptoms of dermatitis herpetiformis. This includes using gentle, fragrance-free soaps and moisturizers, avoiding hot showers or baths, and wearing loose-fitting clothing. It may also be helpful to apply cool compresses or take oatmeal baths to help soothe irritated skin.

Remember, managing dermatitis herpetiformis requires a comprehensive approach that addresses both the underlying autoimmune disorder and the associated skin rash. By working closely with your healthcare provider and implementing appropriate treatment options, you can improve your overall health and quality of life.


You may feel overwhelmed and frustrated by the symptoms of dermatitis herpetiformis, but remember that there are treatment options available. By understanding the causes and triggers of this autoimmune skin condition, you can take the first step towards managing it effectively.

Whether you opt for a gluten-free diet, medication, or proper skin care practices, know that these approaches can significantly alleviate your symptoms and improve your overall skin health. With the right treatment, you can take control of your dermatitis herpetiformis and lead a happier, healthier life.
