 [re-fēd´ing]
restoration of normal nutrition after a period of fasting or starvation.
refeeding syndrome moderate to severe electrolyte and fluid shifts occurring during a period of refeeding; hypophosphatemia is common, and heart failure sometimes occurs.

moderate to severe electrolyte and fluid shifts occurring during a period of refeeding. Hypophosphatemia is common, and heart failure sometimes occurs.

refeeding syndrome

The tendency to develop dangerous illness usually within four days of resuming normal eating after a prolonged period of starvation. Low insulin production during starvation with breakdown of body fat and protein result in loss of intracellular electrolytes, especially phosphate. The shift to a carbohydrate metabolism causes increased insulin production which stimulates cellular uptake of phosphate from the blood. Low serum phosphate depletes ATP and causes rhabdomyolysis, respiratory and heart failure, hypotension, seizures and death. Monitoring of serum phosphate and intravenous phosphate supplementation are required.

refeeding

the process of restoring nutrition to a previously starved animal. This should initially consist of a diet of predominantly protein and fat, gradually becoming more complex.

refeeding syndrome
excessive dietary carbohydrate intake after a period of starvation leads to potentially fatal insulin-induced transport of phosphorus and potassium into cells.

Although there are few predictive factors to identify patients most at risk for refeeding syndrome, they tend to be those who are the most underweight (less than 70% of their ideal body weight) and have low prealbumin levels.
b) represents patients at risk of refeeding syndrome (12).
Nasogastric feeding with Osmolite (Abbott Australasia, Kurnell, NSW) was commenced at a slow rate of 40 ml per hour for 96 hours to reduce the risk of refeeding syndrome, then gradually increased over the next 48 hours to meet estimated nutritional requirements.
