[Diagnostic challenges in celiac disease].

Celiac disease (CeD) is caused by an autoimmune reaction triggered by dietary intake of gluten. CeD affects approximately 1% of the population, although many cases remain undiagnosed. CeD is diagnosed by testing for CeD antibodies, and if positive, referral to a gastroenterologist or pediatrician is indicated. Treatment of CeD is a lifelong gluten-free diet. Guidance from a dietitian is needed. Symptoms of CeD vary and are often non-specific, which can cause diagnostic challenges and often a significant diagnostic delay. Therefore, increased awareness of CeD symptoms and knowledge of diagnostic procedures is important, as argued in this review.
