Quick GuideGluten-Free Diet

Gluten-Free Diet

Dermatitis herpetiformis

Dermatitis herpetiformis, also known as Duhring disease, is an intense burning and extremely itchy rash made up of blisters and bumps. It usually occurs equally on both sides and is found most frequently on the elbows, buttocks, knees, scalp, and back. This is sometimes referred to as "the gluten rash" or the "celiac disease rash" and has been used to diagnose celiac disease for some people. Strict adherence to a gluten-free diet is recommended to prevent flares and complications.

Gluten ataxia

Gluten ataxia is an immune-mediated disease caused by the consumption of gluten in genetically susceptible people. Ataxia is poor coordination and unsteadiness due to the brain's failure to regulate the body's posture, and regulate the strength and direction of limb movements. Antigliadin antibodies (AGA) are produced in response to gliadin, the prolamin found in wheat. Gluten ataxia was first detected in 1998 in people who had ataxia with elevated AGAs. All of these patients in this initial description had gait ataxia, some had limb ataxia, and more than half had peripheral neuropathy. About a third had celiac disease. A gluten-free diet is the treatment for gluten ataxia.

Wheat allergy

The nutrients found in food can prevent disease and sustain life. They can also cause health problems in susceptible people. Food allergies can wreak havoc on a person's health and quality of life. Roughly 5% of individuals in Westernized nations have a true food allergy. A true food allergy is an abnormal response to a food triggered by the body's immune system. Symptoms can range from vomiting, diarrhea, and abdominal cramps to hives or eczema to itching and swelling in the mouth or possibly to a life threatening anaphylactic reaction.

Wheat allergy is defined as an adverse immunologic reaction to wheat proteins that is immunoglobulin E (IgE) mediated. It can present as respiratory symptoms (baker's asthma or rhinitis, more common in adults), food allergy (gastrointestinal symptoms of gas, bloating, diarrhea, and abdominal pain, hives, angioedema, or atopic dermatitis; mainly in children) and contact hives (urticaria).

The top eight food allergens in the United States are peanuts, milk, eggs, fish, crustacean shellfish, soybean, tree nuts, and wheat. Only about 0.1% of all food allergies is a wheat allergy. Wheat allergy symptoms usually occur in the mouth, nose, eyes, and throat (swelling, itching, and irritation); the skin (rash, hives, swelling); respiratory tract (wheezing, difficulty breathing, anaphylaxis); and gastrointestinal tract (cramps, nausea, emesis, gas, bloating, diarrhea, and abdominal pain). The testing options for a wheat allergy include either an IgE serum assay or skin prick test to wheat. Only wheat flour is required to be restricted and there should be no permanent damages caused by it.
