Hypervitaminosis D

I-Hypervitaminosis D yimeko eyenzeka emva kokuthatha idosi ephezulu kakhulu yevithamini D.

Unobangela kukutya okuthe kratya kwevithamini D. Amanani kufuneka abe phezulu kakhulu, ngaphezulu kakhulu kunoko uninzi lwababoneleli bezonyango bemisela ngesiqhelo.

Kubekho ukudideka okuninzi malunga nokongezwa kweevithamini D. Isibonelelo semihla ngemihla (i-RDA) se-vitamin D siphakathi kwama-400 nama-800 IU / ngosuku, ngokobudala kunye nenqanaba lokukhulelwa. Amanani aphezulu anokufuneka kwabanye abantu, njengaleyo inesiphene se-vitamin D, i-hypoparathyroidism, kunye nezinye iimeko. Nangona kunjalo, uninzi lwabantu aludingi ngaphezulu kwe-2,000 IU ye-vitamin D ngemini.

Kubantu abaninzi, ivithamin D ityhefu yenzeka kuphela ngeedosi zikavithamini D ngaphezulu kwe-10,000 IU ngosuku.

Ukugqithisa kwe-vitamin D kunokubangela izinga eliphezulu le-calcium egazini (hypercalcemia). Oku kungonakalisa kakhulu izintso, izicubu ezithambileyo, kunye namathambo ngokuhamba kwexesha.

Iimpawu zibandakanya:

• Ukuqunjelwa
• Ukunciphisa ukutya (anorexia)
• Ukuphelelwa ngamanzi emzimbeni
• Ukudinwa
• Ukuchama rhoqo
• Ukucaphuka
• Ubuthathaka bemisipha
• Ukuhlanza
• Unxano olugqithisileyo (polydipsia)
• Igazi elonyukayo
• Ukugqithisa isixa esikhulu somchamo (i-polyuria)

Umboneleli wezempilo uyakukuvavanya akubuze malunga neempawu zakho.

Uvavanyo olunoku-odolwa lubandakanya:

• Calcium egazini
• I-calcium kumchamo
• Amanqanaba e-1,25-dihydroxy vitamin D
• I-serum phosphorus
• X-reyi yethambo

Umboneleli wakho uya kukuxelela ukuba uyeke ukuthatha ivithamin D. Kwiimeko ezinzima, olunye unyango lunokufuneka.

Ukuchacha kulindeleke, kodwa umonakalo osisigxina wezintso ungenzeka.

Iingxaki zempilo ezinokubangelwa kukuthatha ivithamin D eninzi kakhulu ixesha elide zibandakanya:

• Ukuphelelwa ngamanzi emzimbeni
• Hypercalcemia
• Umonakalo wezintso
• Amatye eentso

Fowunela umnikezeli wakho ukuba:

• Wena okanye umntwana wakho ubonakalisa iimpawu ze-hypervitaminosis D kwaye uthathe i-vitamin D engaphezulu kwe-RDA
• Wena okanye umntwana wakho ubonakalisa iimpawu kwaye ebesele ethatha amayeza okanye ifom engu-vitamin D e-okhawuntareni

Ukuthintela le meko, nikela ingqalelo kwiidosi echanekileyo ye-vitamin D.

Uninzi lwezinto zokudibanisa ivithamin ziqulathe ivithamin D, ke jonga iilebheli zazo zonke izongezo ozithathayo kumxholo wevithamin D.
