Calcium imbalance: Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))

Calcium deficit causes nerve fiber irritability and repetitive muscle spasms. Consequently, characteristic symptoms of hypocalcemia include perioral paresthesia, twitching, carpopedal spasm, tetany, seizures and, possibly, cardiac arrhythmias. Chvostek’s sign and Trousseau’s sign are reliable indicators of hypocalcemia. (See Trousseau’s sign. Also see Chvostek’s sign, page 918.)

Clinical effects of hypercalcemia include muscle weakness, decreased muscle tone, lethargy, anorexia, constipation, nausea, vomiting, dehydration, polydipsia, and polyuria. Severe hypercalcemia (serum levels that exceed 15 mg/dl) may produce cardiac arrhythmias and, eventually, coma.

Calcium imbalance: Signs and symptoms
(Handbook of Diseases)

Indications of calcium imbalance depend on the type of imbalance. (See Signs and symptoms of calcium imbalance.)

Hypocalcemia

A lack of calcium causes nerve fiber irritability and repetitive muscle spasms. Consequently, characteristic signs and symptoms of hypocalcemia include perioral paresthesia, twitching, carpopedal spasm, tetany, seizures and, possibly, cardiac arrhythmias. Although Chvostek’s and Trousseau’s signs are reliable indicators of hypocalcemia, they aren’t specific.

Hypercalcemia

Signs and symptoms of hypercalcemia include muscle weakness, decreased muscle tone, lethargy, anorexia, constipation, nausea, vomiting, dehydration, polydipsia, and polyuria. When calcium levels are greater than 3.2 mmol/L (13 mg/dL), calcification in kidneys, skin, vessels, lungs, heart, and stomach occurs and renal insufficiency may develop, especially if blood phosphate levels are normal or elevated due to impaired renal function. Severe hypercalcemia (serum levels that exceed 4.5 mmol/L or greater than 18 mg/dL) may produce cardiac arrhythmias and, eventually, coma.
