Hypercalcaemia, also spelled hypercalcemia, is a high calcium (Ca2+) level in the blood serum. The normal range is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L) with levels greater than 2.6 mmol/L defined as hypercalcemia. Those with a mild increase that has developed slowly typically have no symptoms. In those with greater levels or rapid onset, symptoms may include abdominal pain, bone pain, confusion, depression, weakness, kidney stones, or an abnormal heart rhythm including cardiac arrest.
Most cases are due to primary hyperparathyroidism or cancer. Other causes include sarcoidosis, tuberculosis, Paget disease, multiple endocrine neoplasia (MEN), vitamin D toxicity, familial hypocalciuric hypercalcaemia, and certainmedications such as lithium and hydrochlorothiazide. Diagnosis should generally include either a corrected calcium orionized calcium level and be confirmed after a week. Specific changes may be seen on an electrocardiogram (ECG).
Treatment may include intravenous fluids, furosemide, calcitonin, or pamidronate in addition to treating the underlying cause. The evidence for furosemide; however, is poor. In those with very high levels hospitalization may be required.Hemodialysis may be used in those who do not respond to other treatments. In those with vitamin D toxicity steroids may be useful. Hypercalcemia is relatively common. Primary hyperparathyroidism occurs in between one and seven per thousand people and hypercalcemia occurs in about 2.7% of those with cancer.
