Wheat sensitivity is a collective term for various, primarily gastrointestinal disorders that occur as part of a hypersensitivity reaction following the consumption of wheat. The symptoms, which are usually similar to those of irritable bowel syndrome, are often accompanied by skin changes.
In addition to coeliac disease and dermatitis herpetiformis, the cutaneous manifestation of coeliac disease, wheat sensitivity also includes non-celiac gluten sensitivity (NCGS), allergic nickel contact mucositis, wheat allergy, amylase trypsin inhibitor intolerance and intolerance to fermentable oligosaccharides, disaccharides, monosaccharides and polyols(FODMAP).
