Infant colic: from theory to practice

Abstract

Infant colic is one of the most common, yet least studied, functional disorders of the gastrointestinal tract. Until now, there is no certainty both in the understanding of the nature of this condition and in the approaches to its correction. At the same time, infant crying is of concern to parents, forcing them to seek professional help and incur considerable medical expenses and to resort, sometimes unreasonably, to dietary and medical corrections. This article provides information on the etiology, pathogenesis and management of infantile colic from an evidence-based perspective, based on a review of the current literature. Various preconditions for the occurrence and development of infantile colic are analysed in detail, none of which can affect all occurrences. Evidence for the proven efficacy of including Lactobacillus reuteri in the treatment of intestinal colic in infants is presented. Effects on the gastrointestinal tract microbiome can be of undeniable benefit. Lactobacillus reuteri is one of the most studied and scientifically documented probiotics. 203 completed clinical trials involving 17,200 participants, including 67 trials involving 8,200 participants between 0 and 3 years of age. Numerous placebo-controlled studies have shown that taking Lactobacillus reuteri DSM 17938 can significantly reduce crying time in infants with colic, and in these studies, rates of 50% or more reduction in crying time were 2.3 times higher compared to controls.
