Ngomuthi ovamile we-calcium egazini, abesifazane kudingeka bagcinwe. Lesi sici sithatha inqubo ehlukahlukene eyenzeka emzimbeni. Ukuphambuka kwezinga lokuqukethwe kwalo okuvela esimweni esijwayelekile kuyisibonakaliso sokuphulwa komsebenzi wesistimu ethile kanye nesenzakalo sokwenza ucwaningo.
Iyini izinga elivumelekile le-calcium egazini labesifazane?
I-calcium iqukethe amathambo abantu namazinyo. Ngaphezu kwalokho, into esiza ukwenza imisebenzi enjalo:
- kujwayelekile ukwenza isigqi senhliziyo;
- ulawula inqubo yokushintshaniswa kwensimbi;
- ubamba iqhaza ekukhunjweni kwemisipha;
- kuthinta inqubo yokweqa igazi;
- iyingxenye ekudlulisweni kwemizwa ye-nerve kanye nokulawulwa kwesimiso sezinzwa.
Okujwayelekile kubafazi kuthathwa njengezinga le-calcium egazini, kusukela ku-2.15 kuya ku-2.5 mmol / l. Amangqamuzana namazinyo aqukethe kuphela iphesenti yenani lezinkinga. Cishe u-40% we-calcium ephelele ubophezela ku-albinini. Okunye kungenxa ye-calcium yamahhala.
Umkhuba we-ionized - free-calcium egazini labesifazane uncane. Okungcono, inani lendaba "elikude" kufanele linqunywe ngokwehlukana. Kodwa empeleni, kunzima kakhulu ukuqhuba isifundo ukucacisa inani le-calcium ioniwe egazini. Ngakho-ke, kuvame ukukholelwa ukuthi izinga lempahla lingaphezu kwengxenye ye-calcium yenani - 1.15 -1.27 mmol / l.
Uma okuqukethwe kwe-calcium ephelele egazini labesifazane kuhlulekile
Ngokuvamile, ukunciphisa inani le-calcium kubonisa ukuntuleka kwevithamini D. Ngaphezu kwalokho, i-hypocalcemia ingabangelwa yi:
- imikhiqizo ethile yezokwelapha;
- ukudla okungalungile;
- izifo ze-gland yegciwane;
- ukwephulwa kwe- acid-base balance ;
- i-pancreatitis enzima;
- i-hypoparathyroidism;
- ukuhlukunyezwa kwemikhiqizo equkethe i-caffeine;
- ukuchithwa isikhathi eside;
- i-pancreatitis engapheliyo.
Kukholelwa ukuthi uma i-calcium enganele, lokhu kubonisa ukuthi i-osteoporosis. Kodwa noma yiliphi udokotela uzoqinisekisa ukuthi i-hypocalcemia ayiyona into esemqoka yesifo.
Ukwedlula izinga le-calcium ephelele egazini labesifazane
I-Hypercalcemia nayo ibhekwa njengento engathandeki. Izici ezilandelayo zisiza ukuthuthukisa lesi sifo:
- i-hypervitaminosis D;
- ukulungiswa kwefa;
- i-sarcoidosis;
- izicubu ezinhle futhi ezimbi;
- ukuxhashazwa kwemithi ethile kanye nezithako zokudla;
- i-hyperthyroidism ;
- ukwephulwa kwe-calcium metabolism;
- ukuphazamiseka kwesimiso sezinzwa.
