title: Refeeding syndrome: a potentially fatal condition but remains underdiagnosed and undertreated.
abstract: OBJECTIVE
  To describe two cases of successfully prevented refeeding syndrome in a high-risk group of patients.
  
  
  METHODS
  Case 1 was a 70-y-old woman who presented with a 4-mo history of poor dietary intake and ill health due to a connective tissue disease leading to myositis and dysphagia and complicated by respiratory failure needing mechanical ventilation. Twelve hours after starting nasogastric tube feeding, she developed a cardiac arrest from which she was successfully resuscitated. Repeated attempts to wean her from the ventilator failed. Case 2 was a 15-y-old girl who was readmitted after a total colectomy for severe ulcerative colitis with diarrhea and vomiting leading to significant weight loss. Her body mass index was 11.4 kg/m(2).
  
  
  RESULTS
  In case 1, after consultation by the clinical nutrition team, the diagnosis of refeeding syndrome was made and the patient was duly started on a high-protein, high-fat, low-carbohydrate diet, multivitamin and trace-element supplements, and electrolyte infusion. Subsequently she was successfully weaned from the ventilator. In case 2, further investigation by the clinical nutrition team revealed low baseline electrolyte concentrations including potassium, magnesium, calcium, and phosphate and low serum albumin. Her low body mass index and baseline electrolyte concentrations put her at high risk of developing refeeding syndrome. She was initially started on low-calorie feeding, multivitamin and minerals, and her electrolytes were carefully monitored. She made a good recovery.
  
  
  CONCLUSIONS
  Refeeding syndrome is a life-threatening, underdiagnosed, treatable condition but there is a need for a wider awareness of the condition among health professionals.
