Coeliac disease
long term autoimmune disorder caused by a reaction to gluten
Coeliac disease (Commonwealth English) or celiac disease (American English) is a chronic autoimmune disease, mainly affecting the small intestine. It is caused by an abnormal immune system response to gluten, a protein found in wheat and other grains such as barley and rye. Coeliac disease causes a wide range of symptoms and complications that can affect multiple organs outside the gastrointestinal tract.
The classic form of the disease can affect any age group, but is usually diagnosed in early childhood and causes symptoms of malabsorption such as weight loss, diarrhoea, and stunted growth. Non-classic coeliac disease is more commonly seen in adults, characterised by vague abdominal symptoms and complications in organs outside the gastrointestinal tract, such as bone disease, anaemia, and other consequences of nutritional deficiencies. In people with a genetic predisposition to the condition, eating gluten causes inflammation in the small intestine, damaging its lining and leading to malabsorption. The development of coeliac disease is believed to be influenced by other environmental factors, such as infections.
Diagnosis is based on symptoms, blood tests, and biopsies of the small intestine. For people who have already cut gluten from their diet, gluten may need to be reintroduced before testing to ensure an accurate diagnosis. A lack of awareness and the diverse symptoms, which overlap with other disorders, often complicate the diagnosis by leading to a delay in diagnosis.
“Coeliac disease” enters the record as long term autoimmune disorder caused by a reaction to gluten. Crown Archives preserves that source wording while asking what Coeliac, disease and long can confirm, complicate or overturn.
Why this record matters
“Coeliac disease” is worth following because a concise public description often conceals a longer documentary argument. Here, Coeliac, disease and long provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q11088. The Library of Congress control number is sh85021632. None of the 1 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
