Celiac disease is a genetic disease characterized by the permanent abnormal response to gluten which is an ingredient of wheat, barley and rye, and derivatives thereof. The Republic of Croatia has relatively little research on celiac disease, so there is no concrete data on the size of the population that suffers from this disease. To prevent major health problems it is necessary to continuously educate parents and medical staff about this disease. Celiac disease can develop at any age, but its symptoms are usually found in children that are introduced to a diet that contains gluten. The treatment for celiac disease is lifelong adherence to a strict gluten-free diet, because even small amounts of gluten can possibly lead to unwanted complications. It is important to properly educate parents so that they know how to apply adequate nutrition. The disease is diagnosed based on biopsy of the lining of the small intestine, and also on a positive clinical response to the exclusion of gluten from the diet. Weather celiac disease, if detected early and adhere to a gluten-free diet is very good. In this paper, the research was conducted in order to determine which gender is more susceptible to celiac disease, which significant symptoms were noticed among children, the effect of breastfeeding on celiac disease and whether the time of gluten introduction in the diet was important for the development of the disease. The subject of research was also whether the children suffering from celiac disease feel stigmatized and determining the percentage of preschool children with celiac disease attending kindergarten. The survey included 119 participants, and the results show that 62.2% of surveyed children suffering from celiac disease are female, most children had no complications (77.3%), and complications are higher in children who have started to introduce gluten before the age of 6 months. A small percentage of children is attending kindergartens (24%), and most kindergartens (61.3%) do not prepare meals for gluten free diet.
