Refeeding syndrome: Rapid weight gain is dangerous for patients who weigh less than 70% of their ideal weight, those who have lost weight rapidly and patients who've had little or no nourishment in the past 10 days. These patients are subject to fluid and electrolyte shifts that can cause marked edema and intracellular phosphate depletion. Congestive heart failure and respiratory failure can occur.
