Artificial Nutrition

Definition

Administration of nutrients through non-oral routes, bypassing the digestive system, used when patients cannot eat or absorb food normally. It includes enteral and parenteral nutrition methods.

How it works

Artificial nutrition is essential for patients with severe malnutrition, inability to swallow, gastrointestinal disorders, or critical illness. It can be delivered either through the digestive tract (enteral) via feeding tubes, or directly into the bloodstream (parenteral) via catheters. The choice depends on gastrointestinal function, duration of support needed, and clinical status. These methods maintain metabolic function and prevent severe protein-energy malnutrition when oral intake is compromised.

Role

Maintains nutritional status and prevents complications in patients unable to consume food orally, supporting recovery and metabolic homeostasis.

Examples

• Nasogastric feeding
• Parenteral nutrition in post-surgical patients
• Jejunostomy feeding in burn victims
• Long-term support in neurological disorders

Recommendations

Assess gastrointestinal function before choosing the route. Monitor tolerance, fluid balance, and nutritional markers regularly. Transition to oral feeding as soon as clinically feasible to maintain gut integrity.

Key takeaway

Artificial nutrition is a life-saving intervention when oral intake is impossible, maintaining nutritional status during critical illness or recovery.
