Enteral feeding means using the gastrointestinal tract for the delivery of nutrients, which includes eating food, consuming oral supplements and all types of tube feeding. The routes of enteral feeding most often used are naso-gastric tubes (NGT) and percutaneous endoscopic gastrostomy (PEG) tubes. Other routes that are increasingly being used include naso-jejunal and jejunostomy feeding, which may be the only feasible route if it is not appropriate to feed via the stomach.
