Refeeding Syndrome (3) Flashcards
Who does this occur in?
How does the BMI affect the risk of it?
What is the pathophysiology of it?
What is the pt at risk of as a result?
➊ Those who start to eat again after being in severe nutritional deficit for a prolonged time
➋ The lower the BMI, the higher the risk of refeeding syndrome
➌ During the malnutritional period, metabolism in cells slows down. When giving food quickly, the Insulin boost pushes magnesium, potassium and phosphorus into cells, therefore leading to:
• Hypomagnesaemia
• Hypokalaemia
• Hypophosphataemia
➍ Arrhythmia’s, HF and Fluid overload
How is it managed?
• Slow reintroduction of food w/restricted calories
• Routine bloods to monitor Mg, K, Phos, Glucose
• ECG monitoring
• Fluid balance monitoring
• Bloods - LF/FSH, TFTs
• Supplementation with electrolytes, vitamins (B and Thiamine/B1)
