Enteral nutrition provides calories, protein, fluids, vitamins, and minerals through the digestive tract. It can include specially formulated nutrition taken by mouth or delivered through a feeding tube. Tube feeding is used when a person cannot safely eat enough but still has a functioning stomach or intestine. The formula and feeding schedule are selected according to the person's nutritional and medical needs.
read more about enteral nutrition ...Enteral nutrition can support people who have difficulty chewing, swallowing, or consuming enough food. It is used in conditions such as stroke, neurological disease, head or neck cancer, critical illness, severe injury, and impaired consciousness. It can also help people with increased nutritional needs or prolonged loss of appetite. The digestive tract must be able to absorb and move nutrients adequately for enteral feeding to be suitable.
Liquid formula can be given continuously with a pump, at scheduled intervals, or as larger bolus feedings. Feeding can enter the stomach or small intestine depending on the person's condition and aspiration risk. Water is also provided to maintain hydration and flush the tube. A dietitian or clinical team calculates the formula amount, calorie target, protein needs, fluid volume, and feeding rate.
Short-term feeding commonly uses a nasogastric tube that passes through the nose into the stomach or a nasoenteric tube that reaches the small intestine. Longer-term access can use a gastrostomy tube placed through the abdominal wall into the stomach. A jejunostomy tube delivers formula directly into the small intestine. Tube selection depends on expected treatment duration, digestive function, anatomy, and the risk of aspiration.
Possible problems include nausea, vomiting, diarrhea, constipation, bloating, tube blockage, skin irritation, and accidental tube movement. Formula entering the airway can cause aspiration and serious lung complications. The care team monitors weight, hydration, bowel function, blood glucose, electrolytes, and signs of infection or feeding intolerance. Correct positioning, tube flushing, head elevation, and safe formula handling help reduce complications.
Tube feeding is a common form of enteral nutrition, but the broader term can also include nutritionally complete medical formulas taken by mouth. Both methods deliver nutrients through the gastrointestinal tract.
Enteral nutrition uses the stomach or intestine, while parenteral nutrition delivers nutrients directly into the bloodstream through a vein. Parenteral nutrition is considered when the digestive tract cannot be used safely or effectively.
Commercial formulas are commonly used because their nutrient content, consistency, and safety can be controlled. Blenderized food can be appropriate for selected patients when a clinical team provides a suitable recipe and safe handling instructions.
Yes. Home enteral nutrition is possible when the patient or caregiver receives training on feeding, tube care, medication administration, storage, and warning signs that need medical attention.
