Uvavanyo lwe-insulin

I-insulin yihomoni ebalulekileyo eveliswa yipancreas enceda ekulawuleni amanqanaba eswekile yegazi (glucose) emzimbeni. Idlala indima ebalulekileyo ekugcineni ibhalansi yamandla kunye ne-metabolism ngokubanzi ngokuququzelela ukuthatyathwa kwe-glucose kwiiseli zamandla okanye ukugcina. Uvavanyo lwe-insulin sisixhobo sokuxilonga sezonyango esilinganisa amanqanaba e-insulin egazini ukunceda ukuxilonga nokubeka iliso kwisifo seswekile, ukunganyangeki kwe-insulin, kunye nezinye iimeko zemetabolism.

Yintoni uvavanyo lwe-insulin?

Uvavanyo lwe-insulin luvavanyo lwegazi olulinganisa isixa se-insulin egazini. I-insulin iyimfuneko ekulawuleni amanqanaba e-glucose yegazi, kwaye uvavanyo lunokubonelela ngengqiqo ebalulekileyo malunga nendlela umzimba wakho olawula ngayo le nkqubo ibalulekileyo. Ngokukodwa, uvavanyo lwe-insulin lunokunceda ukubona ukunganyangeki kwe-insulin, uhlobo lwe-1 yeswekile, uhlobo lwe-2 yeswekile, kunye nezinye iziphazamiso ezinxulumene nokuveliswa kwe-insulin engaqhelekanga.

Uvavanyo lwe-insulin lunokwenziwa ngokuzimeleyo okanye ecaleni kwezinye iimvavanyo, ezifana novavanyo lwe-glucose okanye uvavanyo lwe-A1C, ukujonga ngokubanzi impilo yakho ye-metabolic.

Iintlobo zovavanyo lwe-insulin

Kukho iintlobo ezimbini eziphambili zovavanyo lwe-insulin:

• Uvavanyo lokuzila ukutya kwe-insulin: Olu vavanyo lulinganisa inqanaba le-insulin emva kokuzila ukutya (ngokuqhelekileyo kwiiyure ze-8-12) ngaphandle kokutya okanye ukusela nantoni na ngaphandle kwamanzi. Amanqanaba e-insulin yokuzila ukutya asetyenziswa ukuvavanya impendulo ye-pancreas kumanqanaba eswekile kwaye aqhele ukusetyenziswa ukufumanisa ukunganyangeki kwe-insulin.
• Uvavanyo lwe-insulin olungaqhelekanga: Olu vavanyo lulinganisa amanqanaba e-insulin nanini na emini, ngaphandle kwesidingo sokuzila ukutya. Ingasetyenziselwa kunye novavanyo lwe-glucose ukuvavanya ukuveliswa kwe-insulin kunye nokukhutshwa.

Lusebenza njani uvavanyo lwe-insulin?

Uvavanyo lwe-insulin lubandakanya ukuzoba isampuli yegazi, ngokwesiqhelo ukusuka kumthambo ongalweni wakho. Igazi ke lihlalutywe ukulinganisa inani le-insulin ekhoyo kwigazi. Amanqanaba e-insulin anokwahluka imini yonke ngokuxhomekeke kwizinto ezifana nokutya, ukuzivocavoca umzimba, kunye nokusebenza ngokubanzi kwemetabolism.

Xa amanqanaba eswekile yegazi enyuka emva kokutya, i-pancreas yakho ikhupha i-insulin ukunceda iiseli zifunxe iswekile kwaye zilawule iswekile yegazi. Ukuba amanqanaba e-insulin akaqhelekanga okanye anyukile, oko kunokubonisa ukuba i-pancreas iyasokola ukuhambisana neemfuno ze-insulin zomzimba, ezinokukhomba ukuxhathisa kwe-insulin okanye eminye imiba ye-metabolic.

Kutheni lenziwa uvavanyo lwe-insulin?

Uvavanyo lwe-insulin lwenziwa ngezizathu ezahlukeneyo, ngakumbi ukubeka iliso kunye nokuxilonga iimeko ezinxulumene nokuveliswa kwe-insulin kunye ne-glucose metabolism. Ezinye zezizathu eziqhelekileyo zokwenziwa kovavanyo ziquka:
