The Coeliac Disease Resource Centre, abbreviated CDRC, is described in this dictionary’s source as a password-protected information service for healthcare professionals involved in treating coeliac disease. Such professional resources provide clinicians and dietitians with up-to-date guidance on diagnosis, the gluten-free diet, nutritional deficiencies, follow-up testing, and managing refractory cases. Restricting access to professionals reflects the complexity of the condition: the gluten-free diet must be strict yet nutritionally adequate, and misdiagnosis carries consequences. For patients, the public-facing equivalents are charities such as Coeliac UK, which translate the same evidence into everyday guidance.
