Functional gastro-intestinal disorder algorithms focus on early recognition, parental reassurance and nutritional strategies.

Abstract Up to 50% of infants present with symptoms of regurgitation, infantile colic and, or, constipation during the first 12 months of life. Although they are often classed as functional disorders, there is an overlap with cows' milk allergy. We present practical algorithms for the management of such disorders, based on existing evidence and general consensus, with a particular focus on primary healthcare. Management consists of early recognition of warning signs of organic disease, parental reassurance and nutritional strategies. CONCLUSION: The proposed algorithms aim to help healthcare providers manage frequent gastrointestinal and cows' milk related symptoms in infants safely and effectively.
