ICD-11 code : 5B91.0;
Preferred Label : Hypercalcaemia;
ICD-11 definition : Hypercalcaemia is a condition caused by increased calcium levels. The higher the calcium
levels and the faster its level rises, the more severe will be the symptoms. When
present, symptoms are caused by dehydration secondary to urinary losses of calcium,
water and other electrolytes, and to an increase in membrane potential caused by the
elevation in extracellular fluid ionized calcium concentration. Patients with moderate
to severe hypercalcaemia often complain of nausea and vomiting, symptoms likely related
to dehydration as well as to the effects of the hypercalcaemia on central nervous
system function. Because hypercalcaemia tends to hyperpolarize membranes, a range
of neurologic and neuromuscular signs and symptoms can occur. Patients with mild hypercalcaemia
often complain of fatigue, depressed mood and asthenia. Gastrointestinal motility
is impaired; this commonly results in constipation.;
