Ngokwe-theoretically, kunzima kakhulu ukubala inani elidingekayo le-insulin - umthamo ofanayo olawulwa yiziguli ezahlukahlukene ungadala ukusabela okuhlukile komzimba, ngenxa yokusebenza komuthi, isikhathi nobude besenzo sawo. Ukubalwa kwenani le-insulin kwenziwa esibhedlela, lowo onesifo sikashukela unquma inani lelo, alihambise ngamandla omzimba, athathe ukudla noshukela egazini.
Izinhlobo zama-insulin zokuphatha
- Umjovo owodwa we-insulin osebenza isikhathi eside noma ophakathi nendawo;
- Ukujova kabili kwe-insulin yangaphakathi;
- Ukujova kabili kwe-insulin esezingeni eliphakathi nendawo nelifushane;
- Kathathu umjovo we-insulin omfushane futhi owenziwe isikhathi eside;
- Isisekelo uhlelo lwe-bolus.
Inqubo yokuzitholela kwemvelo okwenziwa nsuku zonke kwe-insulin ingamelwa ngesimo somugqa onama-vertices ngezikhathi zekhonkco le-insulin elenza ihora elilodwa ngemuva kokudla (Umfanekiso 1). Isibonelo, uma umuntu ethatha ukudla ngo-7 a.m., 12 p.m., 6 p.m. no-10 p.m. khona-ke isilinganiso se-insulin sizokwenzeka ngo-8 a.m., 1 p.m. 7 p.m no 11 p.m.
Ijika lamasango emvelo linezigaba eziqondile, ukuxhuma esithola isisekelo - umugqa. Izingxenye eziqondile zihambelana nezikhathi lapho umuntu ongenaso isifo sikashukela engadli futhi i-insulin ikhishwa kancane. Ngesikhathi sokukhishwa kwe-insulin ngemuva kokudla, umugqa oqondile wokuqothuka kwemvelo uhlukaniswe iziqongo zezintaba ngokukhuphuka okukhulu kanye nokwehla okungatheni.Umjovo owodwa we-insulin osebenza isikhathi eside noma ophakathi nendawo
Umjovo owodwa ubangelwa ukwethulwa komthamo we-insulin nsuku zonke ekuseni ngaphambi kokudla kwasekuseni.
Isenzo salesi sikimu ijika eliqhamuka ngesikhathi sokuphatha umuthi, lifinyelela inani eliphakeme ngesikhathi sasemini futhi lehlela phansi kuzodla isidlo sakusihlwa (igrafu 2)
- Ijika elilodwa-elilodwa-mancane amathuba okuba lifane nejika lemvelo lokufihlwa kwe-insulin.
- Ukusetshenziswa kwalolu hlelo kufaka phakathi ukudla izikhathi eziningana ngosuku - isidlo sasekuseni esikhanyayo sithathelwa indawo isidlo sasemini esiningi, isidlo sasemini esiningi nokudla okuncane.
- Inani nokwakheka kokudla kufanele kuhambisane nokusebenza kwesenzo se-insulin okwamanje kanye nezinga lomsebenzi womzimba.
Ukwethulwa komthamo obalulekile we-insulin kuphazamisa umzimba we-metabolism, okungaholela ekwakhekeni kwezifo ezihlangene.
Lolu hlelo alunconywa kubantu abanesifo sikashukela sohlobo 1, uhlobo 2 sikashukela, ukwelashwa kusetshenziswa ngokubambisana nezidakamizwa ezinciphisa ushukela ezethulwa ngesikhathi sokudla.
Ukujova kabili kwesenzo sangaphakathi se-insulin
Lolu hlelo lokwelashwa kwe-insulin lubangelwa ukwethulwa kwezidakamizwa ekuseni ngaphambi kokudla kwasekuseni nakusihlwa ngaphambi kokudla kwakusihlwa. Umthamo wansuku zonke we-insulin uhlukaniswe ekuseni nakusihlwa ngesilinganiso se-2: 1, ngokulandelana (igrafu 3).
- Izinzuzo zesikimu ukuthi ubungozi be-hypoglycemia buncishisiwe, kanti ukwahlukaniswa kwe-insulin emithanjeni emibili kunomthelela kumthamo ophansi ojikelezayo emzimbeni womuntu.
- Okubi kwecebo kufaka okunamathiselwe okuqinile kwirejimeni nasekudla - umuntu onesifo sikashukela kufanele adle ngaphansi kwezikhathi ezi-6 ngosuku. Ngaphezu kwalokho, ijika lesenzo se-insulin, njengasesikhathini sokuqala, likude kakhulu nejika lemvelo le-insulin secretion.
Ukujova kabili kwe-insulin esezingeni eliphakathi nendawo nefish
Esikhathini sikashukela, ngenxa yokuqhathaniswa komthamo we-insulin, kungenzeka ukuthi kuguqulwe imenyu yesifo sikashukela ngokusebenzisa umkhiqizo onokuqukethwe okunoshukela omningi noma ukwandisa inani lokudla okuthathiwe (ishadi 4).
- Uma phakathi nosuku ohlela ngalo isidlo esisebenzayo (ukuhamba, ukuhlanza, ukulungisa), umthamo wasekuseni we-insulin omfushane unyuka ngamayunithi ama-2, futhi umthamo ophakathi nendawo uyancipha ngamayunithi ama-4 - 6, njengoba ukusebenza komzimba kuzoba nomthelela ekwehliseni ushukela;
- Uma umcimbi ohlonishwayo ngokudla okuningana kuhlelelwa kusihlwa, umthamo we-insulin omfushane kufanele ukhuphuke ngamayunithi ama-4, ophakathi nendawo - ushiye ngokulinganayo.
Ngaphandle kwezinzuzo, uhlelo alunazo izithiyo, olunye lwazo oluhambisana nokudla okunzima. Uma ukwelashwa kwe-insulin okuphindwe kabili kukuvumela ukuthi uguqule uhla lokudla, khona-ke ukuphambuka ohlelweni lokudla okunqatshelwe akuvunyelwe ngokuphelele. Ukuphambuka ohlelweni lwesigamu sehora kusongela ngokuvela kwe-hypoglycemia.
Kathathu umjovo we-insulin emfushane nehlala isikhathi eside
Ukujova okwenziwa kathathu kwe-insulin ekuseni nantambama kuhambelana nohlelo lwangaphambilini lokwelashwa okuphindwe kabili, kepha kuguquguquka ngokwengeziwe kusihlwa, olwenza kube ngcono. Uhlobo lolo lubandakanya ukuphathwa kwengxube ye-insulin efushane nehlala isikhathi eside ngaphambi kokudla kwasekuseni, imithamo ye-insulin emfushane ngaphambi kwasemini kanye nedosi elincane le-insulin ende ngaphambi kokudla kwakusihlwa (Umfanekiso 5).Isisekelo - Isikimu seBolus
Ngohlobo lwasisekelo-bolus lokuphathwa kwe-insulin, uhhafu wethamo eliphelele liwela kwi-insulin esebenza isikhathi eside, nengxenye kwenye "emfishane". Izingxenye ezimbili kwezintathu ze-insulin isikhathi eside ziphathwa ekuseni nantambama, ezinye ziphumule kusihlwa. Umthamo we-insulin "omfishane" kuncike kunani kanye nokwakheka kokudla okuthathiwe.
