| has gloss | (noun) abnormally low level of calcium in the blood; associated with hypoparathyroidism or kidney malfunction or vitamin D deficiency hypocalcaemia, hypocalcemia |
| has gloss | eng: In medicine, hypocalcemia is the presence of low serum calcium levels in the blood, usually taken as less than 2.1 mmol/L or 9 mg/dl or an ionized calcium level mm of less than 1.1 mmol/L (4.5 mg/dL). It is a type of electrolyte disturbance. In the blood, about half of all calcium is bound to proteins such as serum albumin, but it is the unbound, or ionized, calcium that the body regulates. If a person has abnormal levels of blood proteins, then the plasma calcium may be inaccurate. The ionized calcium level is considered more clinically accurate in this case. In the setting of low serum albumin (frequently seen in patients with chronic diseases, hepatic disease or even long term hospitilization), the formula for corrected calcium is: CorrCa = Measured serum Ca + [(4.0 - measured serum albumin) * 0.8]. Thus, if the albumin is low, the measured calcium may appear low when in fact it is physiologically within normal limits. |

| has gloss | ces: Hypokalcémie je stav sníženého množství vápníku v krvi. Je způsobena ztrátami vápníku (např. při otravě fluorovodíkem , ale i z řady jiných příčin) nebo jeho nedostatečným příjmem. Nejčastěji je způsobována absencí (chirurgickou extrakcí nebo autoimunitním zničením) příštítných tělísek. Závažnost hypokalcémie se může pohybovat od bezpříznakové abnormality až po život ohrožující stav. |

| has gloss | deu: Von Hypokalzämie (auch Hypocalcämie, Hypocalciämie oder Hypokalziämie) spricht man, wenn der Calciumspiegel im Blutserum unter 2,2 mmol/l (9 mg/dl) oder der Gehalt von Calciumionen unter 1,1 mmol/l (4,5 mg/dl) liegt. Sie bewirkt eine Störung des Gleichgewichts zwischen verschiedenen Elektrolyten und kann zu einer Übererregbarkeit des Nervensystems führen, was sich in Krämpfen in der Skelettmuskulatur äußert. In einigen Fällen wird auch ein Spasmus der glatten Muskulatur ausgelöst. Im Allgemeinen wirkt das Parathormon der Hypocalciämie kurzfristig entgegen, Calcitriol dient der längerfristigen Anpassung des Calciumspiegels an Normwerte. |

| has gloss | fra: L hypocalcémie est un état caractérisé par un taux de calcium dans le sang (calcémie) anormalement bas, indépendamment des autres constantes biologiques. La calcémie doit être corrigée avec le taux dalbumine dans le sang (par la formule : Ca corrigée = Ca + (40 - Albu)/40) ; elle est basse en dessous de 2,20 mmol/l . Mécanisme |

| has gloss | spa: Se considera hipocalcemia cuando el nivel sérico de calcio total es menor de 2,1 mmol/L ó 8,5 mg/dL y presenta efectos fisiopatológicos. También puede ocurrir como consecuencia de disminución de la fracción del calcio ionizado: los niveles bajos de calcio impiden que la troponina inhiba la interacción actina-miosina, observándose un incremento del nivel de contracción muscular o incluso tetania. |

| has gloss | tur: Süt humması veya hipokalsemi, kan kalsiyum seviyesini düzenleyen paratroid hormonunun doğum sonrası işlev gösterememesi sonucunda oluşur. Doğum felci daha çok yüksek süt verimli sığırlarda doğum sonrası görülen metabolik bir hastalıktır. Hayvan doğum yaptıktan sonra sağıldığı için sütle birlikte vücuttan fazla miktarda kalsiyum dışarı verilmektedir. Bu hastalığın en önemli çıkış sebebi kandaki iyonize kalsiyumun doğumdan hemen sonra ilk süt verimiyle beraber azalmasıdır. Genetik yatkınlık, doğum öncesinde hayvanların yanlış beslenmeleri, yüksek süt verimi, kalsiyumca zengin yemlerle fazla beslenme, mera ve rasyonun magnezyum miktarı hastalık oluşumunda önemli etmenlerdir. Doğum haricinde hipoprotidemi, renal yetmezlik, hipoparatiroidi, pankreatit, malabsorbsiyon sendromu gibi durumlarda da görülebilir. |

| has gloss | vie: Hạ canxi máu (tiếng Anh: hypocalcemia) được định nghĩa là nồng độ canxi huyết tương toàn phần thấp hơn 2,2 mmol/l (hay 8,8 mg/dL). Một cách chính xác hơn, hạ canxi máu được định nghĩa khi nồng độ canxi ion hóa trong huyết tương thấp hơn 1,16 mmol/l (hay 4,6 mg/dL) bởi chính phần canxi ion hóa này mới là phần canxi lưu hành có tác dụng sinh học và được điều hòa bởi các hormone của cơ thể. |
