AbstractCoeliac disease is the most common immune-mediated enteropathy, affecting approximately 1 % of the population worldwide. Currently, the vast majority of individuals remain undiagnosed. Coeliac disease is triggered by gluten ingestion in genetically predisposed individuals carrying the human leukocyte antigen (HLA) genes; HLA-DQ2 and HLA-DQ8. Patients with coeliac disease present with a wide spectrum of gastrointestinal and extraintestinal manifestations and, in some cases, without any symptoms. The diagnosis of coeliac disease in adults is based on a combination of clinical suspicion, positive serological markers and histological evidence of small intestinal atrophy on duodenal biopsies. The only effective treatment is a strict, lifelong gluten-free diet. However, up to 20 % of patients report persistent or recurrent symptoms. In this review, we provide a comprehensive update on coeliac disease, focusing on its relevance to the different medical specialities and highlighting the need for a multidisciplinary approach to its diagnosis and management. Clinicians practicing internal medicine have a unique opportunity to diagnose this multisystem autoimmune disease. By doing so, they would avoid delays in diagnosis for these patients. A low threshold for serological testing is recommended.Copyright © 2025 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.
