[citation needed], Hypoparathyroidism is a common cause of hypocalcemia. Resources and support. Only the unbound calcium is physiologically active. Low magnesium is typically due to decreased absorption of magnesium in the gut or increased excretion of magnesium in the urine. When calcium levels are high in the cells and the extracellular fluids, as they are in most adults, magnesium levels are corresponding low. // Leaf Group Lifestyle. Both babies and adults suffering from hypocalcemia are at risk of seizures because of the condition. Other symptoms of hypocalcaemia include abdominal cramps, mood changes, and general weakness.

[2] If due to hypoparathyroidism, hydrochlorothiazide, phosphate binders, and a low salt diet may also be recommended. If the building material is absent, they become weak. Normal blood calcium level is between 8.5 to 10.5 mg/dL (2.12 to 2.62 mmol/L) and that of unbound calcium is 4.65 to 5.25 mg/dL (1.16 to 1.31 mmol/L). Since calcium is also bound to small anions, it may be more useful to correct total calcium for both albumin and the anion gap. [7] The symptoms can be recalled by the mnemonic "CATs go numb" - convulsions, arrhythmias, tetany, and numbness in the hands and feet and around the mouth.
