Refeeding syndrome causes dangerous fluctuations in :
Answer: A
Refeeding syndrome causes dangerous shifts in electrolytes.
When a starved or severely malnourished person is fed, especially with carbohydrate, insulin rises and drives phosphate, potassium and magnesium into the cells. Blood levels of these electrolytes fall sharply; hypophosphataemia is the hallmark, and it can lead to heart failure, arrhythmia and respiratory failure. Feeding is therefore started slowly with electrolyte and thiamine replacement.
Liver enzymes, triglycerides and ketone bodies may change during refeeding, but they are not what makes the syndrome dangerous or defines it.
