Let an agent explain hypercalcaemia, relay causes, symptoms, assessment and general management from endocrinology sources, describe the conditions the registry aliases name, and distinguish hypercalcaemia from hypocalcaemia, osteoporosis and calcium intake, routing severe symptoms urgently.

Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain hypercalcaemia, relay causes, symptoms, assessment and general management from endocrinology sources, describe the conditions the registry aliases name, and distinguish hypercalcaemia from hypocalcaemia, osteoporosis and calcium intake, routing severe symptoms urgently.

An abnormally high level of calcium in the blood, most often caused by primary hyperparathyroidism or cancer, including tumour-induced hypercalcaemia, with other causes such as tertiary hyperparathyroidism in chronic kidney disease, vitamin D excess, medications and familial hypocalciuric hypercalcaemia types 1, 2 and 3, a usually benign inherited condition; symptoms range from none to thirst, confusion, kidney stones and heart rhythm problems. Severe symptoms need urgent care. The model routes people to clinicians.

What it is for: Not applicable; a metabolic abnormality.

It can be route severe symptoms first; explain causes; relay assessment and management; distinguish related conditions.

Distinguishing features

High calcium

Often found on tests

Parathyroid or cancer causes

Benign familial form

What it looks like

Not a visible object; a blood test finding.

Physical character

normal total calcium: about 2.2-2.6 mmol/L - varies by lab

main causes: primary hyperparathyroidism and cancer note - about 90 percent

FHH genes: CASR, GNA11, AP2S1 list - types 1 to 3

How it is recognised

High blood calcium

Tertiary hyperparathyroidism, familial hypocalciuric hypercalcaemia 1 to 3, tumour-induced hypercalcaemia

Hypocalcaemia is low calcium; osteoporosis is bone loss; dietary calcium is intake

What the second pass must settle

  • Should familial hypocalciuric hypercalcaemia be a separate primary entry?
  • How should endocrinology sources be linked?
  • The registry entry has merged aliases naming genetic subtypes; should they be grouped?
