Hypocalcemia is a medical condition characterized by low calcium levels in the blood serum. [5] The normal range of blood calcium is typically between 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), while levels less than 2.1 mmol/L are defined as hypocalcemic. [1] [3] [6] Mildly low levels that develop slowly often have no symptoms.
Like hypocalcemia, hypercalcemia can be non-severe and present with no symptoms, or it may be severe, with life-threatening symptoms. Hypercalcemia is most commonly caused by hyperparathyroidism and by malignancy, and less commonly by vitamin D intoxication, familial hypocalciuric hypercalcemia and by sarcoidosis. [2]
The Chvostek sign (/ ˈ k v ɒ s t ɪ k /) is a clinical sign that someone may have a low blood calcium level (a decreased serum calcium, called hypocalcemia).The Chvostek sign is the abnormal twitching of muscles that are activated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII).

Other potential symptoms include: nausea and vomiting, a decreased level of consciousness, and breathing difficulties. [2] Symptoms usually begin within 6 hours of taking the medication by mouth. [2] With extended release formulations symptoms may not occur for up to a day. [2] Seizures are rare in adults but in children occur more often. [2]
Deficiency of magnesium can cause tiredness, generalized weakness, muscle cramps, abnormal heart rhythms, increased irritability of the nervous system with tremors, paresthesias, palpitations, low potassium levels in the blood, hypoparathyroidism which might result in low calcium levels in the blood, chondrocalcinosis, spasticity and tetany, migraines, epileptic seizures, [7] basal ganglia ...
Dialysis can, however, increase the excretion of calcium by developing hypocalcemia, thus possibly worsening the symptoms and signs of hypermagnesemia. The use of diuretics must be associated with infusions of saline solutions to avoid further electrolyte disturbances (e.g., hypokalemia ) and metabolic alkalosis .
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
[2] [3] By mouth they are used to treat and prevent low blood calcium, osteoporosis, and rickets. [1] By injection into a vein they are used for low blood calcium that is resulting in muscle spasms and for high blood potassium or magnesium toxicity. [2] [4] Common side effects include constipation and nausea. [1]
