Narrative clinical review and expert management recommendations without original empirical data or systematic search methodology

What was done
This narrative review describes the physiological mechanisms, clinical manifestations, risk factors, and practical management strategies for refeeding syndrome in malnourished patients.
What was found
The abstract reports that refeeding risks are driven primarily by carbohydrate-induced insulin release and intracellular shifts, leading to hypophosphataemia, hypomagnesaemia, hypokalaemia, sodium and water retention, and thiamine deficiency. Patients with little or no nutritional intake for over 5 days are at high risk. Recommended management includes generous vitamin and electrolyte supplementation, close monitoring, and initiating caloric intake at 10 to 20 kcal/kg/24 hours before increasing as appetite returns. If complications arise, nutritional intake should be reduced to previous levels, lowered further, or briefly halted while correcting electrolyte and fluid disturbances. No comparative empirical data or quantitative outcome metrics are reported.
Why it matters
It provides a concise summary of the pathophysiology and clinical guidance for safely initiating refeeding in severely malnourished patients.
Limits
The abstract describes a non-systematic narrative review providing expert recommendations rather than a randomized trial or systematic review. No empirical patient cohorts, comparative effectiveness data, or quantitative outcome measures are provided.
