AI Article Synopsis

  • A young male patient experienced severe muscle weakness due to dangerously low potassium and phosphorus levels, but the cause was not clear initially.
  • After further investigation, it was discovered that he had been on a very low-calorie diet, specifically the human chorionic gonadotropin diet, which led to a diagnosis of severe refeeding syndrome.
  • The patient's condition was complicated by rhabdomyolysis, but once his electrolytes were corrected, he fully recovered, highlighting the risks of extreme dieting and the need for detailed medical histories.

Article Abstract

We present the case of a young male patient who presented with paralysing muscle weakness due to severe hypokalaemia and hypophosphataemia. The initial patient history evaluations could not establish the aetiology. Only after we reviewed the patient's history did he reveal that he had been following a severe calorie-restricted regime, the human chorionic gonadotropin diet, which had ended 2 days prior to developing symptoms. This information then allowed us to diagnose severe refeeding syndrome. As a further complication, the patient developed rhabdomyolysis. After correction of serum electrolytes, symptoms resolved completely. This case emphasises the potential harm of severely calorie-restricted diets, often recommended by online 'experts'. Furthermore, we underline the importance of thorough history taking.
