Navigating Digestive Disorders in Young Children: Disorders of Gut-Brain Interaction from Infancy to Toddlerhood

Functional gastrointestinal disorders (FGIDs) in infants and toddlers are common worldwide and cover a variety of disorders associated with chronic, recurrent symptoms attributable to the gastrointestinal tract, but not explained by structural or biochemical abnormalities. Although these disorders have historically been described as “functional”, they are now considered as “disorders of gut–brain interaction” (DGBI) emphasizing that the term “functional” should not be misconstrued to imply a non-organic condition.
