Refeeding syndrome is a potentially life-threatening complication that can occur when nutritional support is reintroduced too quickly to individuals who have been severely malnourished or starved. This can happen in cases of anorexia nervosa, starvation, alcoholism, prolonged fasting, or after major surgery. The core issue involves a rapid shift in fluid and electrolyte balance.

When feeding is restarted, carbohydrates are metabolized, leading to an increased demand for phosphate, potassium, and magnesium. Simultaneously, insulin levels rise, driving these electrolytes, along with thiamine, into the cells. This sudden shift causes a depletion of these critical electrolytes in the bloodstream.

Symptoms of refeeding syndrome can range from mild to severe and may include edema, confusion, tremors, muscle weakness, cardiac arrhythmias, and even respiratory failure. The severity of the syndrome is often related to the degree of malnutrition and the rate of nutritional repletion.

Prevention and management are paramount. Gradual reintroduction of nutrition, starting with low carbohydrate intake and closely monitoring electrolyte levels, is crucial. Close medical supervision is essential during the refeeding process, especially in high-risk individuals. Prompt recognition and treatment of electrolyte imbalances can significantly improve outcomes and prevent severe complications.
