Prevalence of functional dyspepsia in school children

Аннотация

The prevalence of functional dyspepsia in children and adults in different countries varies greatly, which is associated with different diagnostic criteria, and different interpretations of the severity of symptoms. Among Europeans, functional dyspepsia occurs in 20% of individuals, in the USA – in 29%, and in Korea – in 11%. Numerous studies conducted in Western Europe and North America have shown that dyspepsia is the most common manifestation of gastroenterological pathology in older children. The study shows that the trigger mechanism for the formation of functional disorders of the digestive system in these age groups is mainly biological factors: heredity burdened by diseases of the digestive system, past intestinal infections, helminthiases, frequent use of antibiotics, nutritional deficiencies, and others. There is evidence that shows peaks in the rise in incidence in children after school entry and during adolescence.
