Hipocalcemia é definida como uma concentração de cálcio total sérico menor que 8,4 mg/dL ou concentração de cálcio iônico menor que 4,48 mg/dL. As doenças renais são as causas mais comuns de hipocalcemia , além de várias outras . Outras causas são: deficiência de vitamina D, transtornos associados com hipoparatireoidismo genético ou adquirido, terapia com bisfosfonato endovenoso, pós-tireoidectomia e pós-paratireoidectomia, e pancreatite aguda. Hipocalcemia pode estar associada com um espectro de manifestações clínicas variando de poucos sintomas, se a hipocalcemia for leve, a convulsões com risco de vida, insuficiência cardíaca refratária ou laringoespasmo se for grave. Além da gravidade, o ritmo de desenvolvimento de hipocalcemia e sua cronicidade determinam as manifestações clínicas. | |||

Hypocalcaemia is defined as a total serum calcium concentration of less than 8.4 mg/dl (2.1 mmol/litre) or an ionized calcium concentration of less than 4.48 mg/dl (1.12 mmol/litre). There are numerous causes of hypocalcaemia, chronic kidney disease being the most common cause. Other causes are: vitamin D deficiency, disorders associated with acquired or genetichypoparathyroidism , including intravenous bisphosphonate therapy, post-thyroidectomy and post-parathyroidectomy, and acute pancreatitis. Hypocalcaemia may be associated with a spectrum of clinical manifestations, ranging from few symptoms if the hypocalcaemia is mild, to life-threatening seizures, refractory heart failure, or laryngospasm if it is severe. In addition to severity, the rate of development of hypocalcaemia and chronicity determine the clinical manifestations. | |||
