Onlyrecentlyhavegluten-related diseasesbeencategorised CELIAC DISEASE is only one among three gluten-related disorders, the others being Wheat Allergy (WA) and NonCeliac Gluten Sensitivity (NCGS). These were categorically defined by a panel of experts who first met in London in 2011 and then in Munich in 2012. Celiac is an auto-immune disorder, WA is an allergic reaction to gluten. But NCGS is neither allergic nor autoimmune. It is a relatively new term that is ill-defined and still not part of our textbooks, says Pankaj Vohra, founder-director of Celiac India and Beyond, a Delhi-based non-profit.
A range of studies have attempted to clear the air between CD, WA and NCGS. Some individuals who experience distress when eating gluten-containing products and show improvement when following a glutenfree diet may have NCGS, instead of CD. NCGS patients are unable to tolerate gluten and develop an adverse reaction, but this does not lead to damage of the small intestine.
