The influence of the gastrointestinal microbiome on infant colic

Abstract

ABSTRACT Introduction Although infantile colic is relatively frequent, its pathophysiology is not yet understood. The aim of this paper is to provide a better understanding of the link between infantile colic and the gastrointestinal microbiome. Areas covered The gastro-intestinal microbiome may already start to develop in the womb and grows exponentially immediately after birth. Factors influencing the microbiome can cause dysbiosis and precipitate symptoms of colic through several mechanisms such as increased gas production and low grade gut inflammation. Other possible factors are immaturity of the enterohepatic bile acid cycle and administration of antibiotics and other medications during the perinatal period. An effective treatment for all colicky infants has yet to be discovered, but the probiotic Lactobacillus reuteri DSM17938 was shown to be effective in breastfed infants with colic. The scientific databases ‘Pubmed’ and ‘Google scholar’ were searched from inception until 02/2020. Relevant articles were selected based on the abstract. Expert Opinion Recent literature confirmed that the composition of the gastrointestinal microbiome is associated with the development of infantile colic. It can be speculated that full sequencing and bioinformatics analysis to identify the microbiome down to the species level may provide answers to the etiology and management of infantile colic.
