What is refeeding syndrome?

Refeeding syndrome can be defined as the potentially fatal shifts in fluids and electrolytes that may occur in malnourished patients receiving artificial refeeding (whether enterally or parenterally5). These shifts result from hormonal and metabolic changes and may cause serious clinical complications.

Summary points. Refeeding syndrome is a potentially fatal condition, caused by rapid initiation of refeeding after a period of undernutrition.

Why does refeeding syndrome occur?

Takeaway. Refeeding syndrome can develop when someone who is malnourished begins to eat again. The syndrome occurs because of the reintroduction of glucose, or sugar. As the body digests and metabolizes food again, this can cause sudden shifts in the balance of electrolytes and fluids.

The risk is high when a person has an extremely low body mass index. People who have recently lost weight quickly, or who have had minimal or no food before starting the refeeding process are also at significant risk.

What happens when food is reintroduced?

When food is reintroduced, the body no longer has to rely on reserves of fat and protein to produce energy. However, refeeding involves an abrupt shift in metabolism. This occurs with an increase in glucose, and the body responds by secreting more insulin. This can result in a lack of electrolytes, such as phosphorous.

Can refeeding cause hypophosphatemia?

Long-term follow-up care for people who have been treated for malnutrition will need to include many different healthcare professionals depending on the underlying cause, including mental health professionals, specialists, and registered dieticians.

Why do people refeed?

Refeeding syndrome has been observed for decades in people who are starving as the result of capture (such as prisoners of war or people who were in concentration camps), famine, poverty, or illness. When medical professionals encountered severely malnourished people in the past, the assumption was that these starving individuals should be allowed to eat and drink normally—or even take in large quantities of nourishment—to address their prolonged hunger and begin to heal their bodies.

What is the safest rate of refeeding for severely malnourished patients who are in the hospital?

What is the metabolic response to the switch from starvation to a fed state in the initial phase of nutritional answer

Refeeding syndrome (RFS) is the metabolic response to the switch from starvation to a fed state in the initial phase of nutritional therapy in patients who are severely malnourished or metabolically stressed due to severe illness.

What is RFS characterized by?

RFS is characterized by an imbalance of electrolytes (mainly phosphate, potassium, and magnesium), vitamin disturbances ( e.g., vitamin B1 thiamine deficiency), and fluid imbalances , as well as limited organ functions, in some cases leading to mortality [8,9,10,11,12].

What happens when you are starved?

When the body is starved it implements various physiological mechanisms to conserve muscle tissue and slow the metabolism. To achieve this various hormones are increased or decreased, the body begins to burn ketones rather than glucose, and electrolyte stores are used.

Does refeeding increase insulin?

Refeeding increases insulin, decreases glucagon. In refeeding syndrome, food is introduced after prolonged starvation and this leads to an increase in insulin and decrease in glucagon. The body increases metabolism and switches from using ketones as the primary energy source back to glucose.
