Pediatric gastroenterology arose as a sub-specialty of gastrointestinal and paediatrics. It is concerned with the treatment of children's gastrointestinal tracts, livers, and pancreas from infancy until the age of eighteen. Acute diarrhoea, prolonged vomiting, gastritis, and issues with the development of the stomach tract are the main disorders it deals with. The specialisation of paediatric gastroenterology and nutrition is still evolving. Many gastrointestinal (GI) diseases have undergone revolutionary transformations as a result of ongoing research at the bench and at the bedside. The emergence of elemental formulations in nutrition has occurred throughout the previous two decades. In children with substantial protein allergy and malabsorption, this advancement has improved intestinal and nutritional rehabilitation.
