An enteral feeding program is necessary when you cannot eat an adequate amount of nourishment by mouth. Home enteral nutrition provides you with the appropriate amount of calories, protein, carbohydrate, fat and essential vitamins and minerals. Home enteral nutrition is often called tube feeding and may be only a few weeks or for the rest of one's life. Enteral nutrition provides food through a tube placed in the nose, the stomach, or the small intestine. A tube in the nose is called a nasogastric tube (NG) or nasoenteral tube. A tube that goes through the skin into the stomach is called a Gastrostomy (G-Tube) or Percutaneous Endoscopic Gastrostomy (PEG). A tube into the small intestine is called a jejunostomy or Percutaneous Endoscopic Jejunostomy (PEJ) tube.
