AB Hypercalcemia  from  any  cause  can  result  in  fatigue,  depression,  mental  confusion,  anorexia,  nausea,  constipation,  renal  tubular  defects,  polyuria,  a  short  QT  interval,  and  arrhythmias.  CNS  and  GI  symptoms  can  occur  at  levels  of  serum  calcium  >2.9  mmol/L  (>11.5  mg/dL),  and  nephrocalcinosis  and  impairment  of  renal  function  occur  when  serum  calcium  is  >3.2  mmol/L  (>13  mg/dL).  Severe  hypercalcemia,  usually  defined  as  >3.7  mmol/L  (>15  mg/dL),  can  be  a  medical  emergency,  leading  to  coma  and  cardiac  arrest.
