Q
Refeeding syndrome pathogenesis
A
Phosphate stores depleted by starvation
When refed, glucose causes insulin release
- triggers phosphate potassium and magnesium uptake by cells - lead to low levels in blood
- insulin also causes metabolic processes making ADP and 2,3DPG using up phosphate
Lack of phosphorylated intermediates cause myocardial dysfunction etc
