Description:
In refeeding syndrome, the sudden reintroduction of a carbohydrate source causes glucose to be the primary fuel source instead of fatty acids and ketones. This rapid shift causes an increased demand for insulin and the body may not have enough insulin at that point to meet the demand. Thus, hyperglycemia, hypokalemia, hypomagnesemia, hypophosphatemia, and metabolic acidemia may occur. These electrolyte abnormalities may end up resulting in fluid retention, dehydration, and hypotension. Prior to feeding a patient that has been malnourished or who hasn't been eating for a long time, it's recommended to obtain a baseline set of vitals and bloodwork to check for any significant electrolyte abnormalities. Correct those as best you can with IVF therapy or other modalities prior to an initial feeding. Upon feeding, start slowly to avoid any rapid shifts of electrolytes
