Prevention of functional gastrointestinal disorders in neonates: clinical and socioeconomic impact

Infantile colic, gastro-oesophageal reflux and constipation are the most common functional gastrointestinal disorders (FGIDs) affecting infants during the first months of life. Despite infantile colic, functional constipation and regurgitation had a self-limited pattern, they are considered a risk factor for developing different disorders later in life. The pathophysiology of these functional diseases is still controversial but there is growing evidence that an abnormal gut microbiota colonisation may play a crucial role. An early probiotic supplementation could determine a change in colonisation and may represent a new strategy for preventing FGIDs.
