Celiac disease is an immune-mediated systemic disease triggered by intake of gluten in genetically susceptible individuals.The prevalence of celiac disease in the general population is estimated to be 1%in the world.Its prevalence differs depending on geographical and ethnic variations.The prevalence of celiac disease has increased significantly in the last 30 years due to the increased knowledge and awareness of physicians and the widespread use of highly sensitive and specific diagnostic tests for celiac disease.Despite increased awareness and knowledge about celiac disease,up to 95%of celiac patients still remain undiagnosed.The presentations of celiac disease have significantly changed in the last few decades.Classical symptoms of celiac disease occur in a minority of celiac patients,while older children have either minimal or atypical symptoms.Serologic tests for celiac disease should be done in patients with unexplained chronic or intermittent diarrhea,failure to thrive,weight loss,delayed puberty,short stature,amenorrhea,iron deficiency anemia,nausea,vomiting,chronic abdominal pain,abdominal distension,chronic constipation,recurrent aphthous stomatitis,and abnormal liver enzyme elevation,and in children who belong to specific groups at risk.Early diagnosis of celiac disease is very important to prevent long-term complications.Currently,the only effective treatment is a lifelong gluten-free diet.In this review,we will discuss the epidemiology,clinical findings,diagnostic tests,and treatment of celiac disease in the light of the latest literature.
