Refeeding Syndrome: Phosphate Shift Simulator

This simulator models refeeding syndrome, a specific and well-documented risk in clinical nutrition: reintroducing carbohydrates too quickly to a chronically malnourished patient triggers an insulin surge that drives phosphate, potassium and magnesium out of the bloodstream and into cells, sometimes causing dangerous hypophosphatemia. Set the refeeding rate, carbohydrate fraction, starvation severity and IV phosphate supplementation, and watch a 3D population of electrolyte ions migrate from the extracellular space into a field of cells at a rate governed by insulin-driven Na⁺/K⁺-ATPase pump activity, while live readouts track serum phosphate against the real clinical mild/moderate/severe thresholds used in ASPEN and NICE refeeding guidelines.
