The purpose of a new study published in Acta Paediatrica was to carry out a concise review of literature, evaluate the impact of common functional gastrointestinal disorders (FGIDs) – regurgitation, infantile colic and functional constipation, on infants and their families, and to provide an overview of national and international guidelines and peer-reviewed expert recommendations on their management. Here, national and international guidelines and peer-reviewed expert recommendations on the management of regurgitation, infantile colic and functional constipation were examined and summarized as follows: regurgitation, infantile colic and functional constipation cause frequent parental concerns, lead to heavy personal and economic costs for families, and impose a financial burden on public healthcare systems. Guidelines state that the first-line management of these common FGIDs should focus on parental education, reassurance and nutritional advice. Nutritional advice should stress the benefits of continuing breastfeeding while special infant formulas may be considered for non-breastfed infants with common FGIDs. In infants, drug treatment is seldom required, with the exception of functional constipation. Hence, it was inferred that by providing complete and updated parental education, reassurance and nutritional advice, healthcare professionals can optimize the management of FGIDs and related symptoms and reduce the inappropriate use of medication or dietary interventions.
