Wake wezwa ngokuhlolwa kokubekezelela ushukela, noma i-GTT ngamafuphi? Udokotela wakho kungenzeka ukuthi ukutshelile ngakho, noma kungenzeka ukuthi ucele ukuthi kwenziwe. Lokhu ukuhlolwa okubaluleke kakhulu okuhlola ukuthi umzimba wakho usebenzisa noma ugcina ushukela, noma i-glucose ngempela. Odokotela bavame ukusebenzisa lokhu kuhlolwa ukuthola izimo ezifana nesifo sikashukela. Kodwa kunezinye izindlela zokuxilonga isifo sikashukela, njengokuhlolwa kwe-A1C kanye nokuhlolwa koshukela wegazi osheshayo.

Ngakho-ke, kuyini lokhu kuhlolwa kokubekezelela ushukela (`GTT`)?

Kalula nje, imizimba yethu ithola amandla ayo ekudleni esikudlayo, ikakhulukazi ukudla okunama-carbohydrate amaningi. Yilokhu okunikeza amangqamuzana ethu amandla okusebenza. Imizimba yethu igcina futhi le glucose ukuze isetshenziswe kamuva, ikakhulukazi emisipheni yethu nasesibindini. Le glucose egciniwe ibizwa ngokuthi i-glycogen.

Ngakho-ke, ukuze sigcine izinga likashukela egazini lethu lisezingeni elithile, izinqubo ezahlukahlukene zenzeka emzimbeni wethu. Phakathi kwazo , i-hormone ebizwa ngokuthi i-insulin idlala indima eyinhloko . Le insulin ikhiqizwa kuma-pancreas ethu. Uma kukhona inkinga endleleni umzimba wethu osebenzisa ngayo ushukela, izinga likashukela egazini lingakhula kaningi. Yilokho esikubiza ngokuthi i-hyperglycemia. Futhi, ngezinye izikhathi izinga likashukela egazini lingancipha, futhi leso simo sibizwa ngokuthi i-hypoglycemia.

Kunezinhlobo ezahlukene ze-GTT. Esetshenziswa kakhulu yi-Oral Glucose Tolerance Test (OGTT), ehilela ukunikeza isisombululo se-glucose ngomlomo.

Kuvamile ukuzizwa ukhathazekile kancane ngaphambi kwanoma yikuphi ukuhlolwa kwezokwelapha. Kodwa khumbula, into ebaluleke kakhulu ukwaziswa. Kungakhathaliseki ukuthi imiphumela ithini, uzofunda okwengeziwe ngomzimba wakho kunangaphambili. Ngalolo lwazi, wena nodokotela wakho ningenza uhlelo olungcono kakhulu lwempilo yenu esikhathini esizayo.

Kukuziphi izimo lapho kungadingeka wenze lokhu `(GTT)`?

Udokotela wakho angaphakamisa i-GTT ukuze ahlole noma aqinisekise ukuthi kukhona noma yiziphi zalezi zimo ezilandelayo:

• Isifo sikashukela – ngokuvamile singaphambi kwesifo sikashukela, isifo sikashukela sohlobo 2, noma isifo sikashukela sokukhulelwa.
• Isimo esibizwa ngokuthi ukumelana ne-insulin.
• I-hypoglycemia esabelayo - Lokhu ukwehla kwamazinga kashukela egazini ngemva kokudla.
• I-Acromegaly yisimo sama-hormone.
• Izinkinga ezingavamile ze-carbohydrate metabolism.

Kodwa khumbula ukuthi kunezinye izivivinyo ezingasetshenziswa ukuxilonga lezi zimo. Udokotela wakho angayala izivivinyo ezingaphezu kwesisodwa.

Ikakhulukazi ngesikhathi sokukhulelwa, ukuhlolwa kwe-glucose challenge yehora elilodwa kuvame ukwenziwa ukuhlola isifo sikashukela sokukhulelwa . Uma imiphumela ingavamile, udokotela wakho angase akucele ukuhlolwa kokubekezelela ushukela ngomlomo (OGTT) kwamahora amathathu ukuqinisekisa ukuxilongwa noma ukususa lesi simo.

Umuntu kufanele azilungiselele kanjani ngempela i-`(GTT)`?

Njengoba kunezinhlobo eziningana ze-GTT, kungase kube nokwehluka okuncane endleleni okudingeka uzilungiselele ngayo kuye ngokuhlolwa okwenzayo. Kodwa ngokuvamile, nansi izinto okudingeka uzenze:

• Kufanele utshele udokotela wakho ngayo yonke imithi kanye nezithasiselo ozithathayo, njengoba eminye imithi ingathinta imiphumela yokuhlolwa. Udokotela wakho angase akucele ukuthi uyeke ukuthatha imithi ethile ezinsukwini ezimbalwa ngaphambi kokuhlolwa.
• Kufanele udle ngokujwayelekile okungenani izinsuku ezintathu ngaphambi kokuhlolwa. Kubalulekile ukudla ukudla okuhlinzeka okungenani amagremu angu-150 ama-carbohydrate ngosuku.
• Ungayishintshi imisebenzi yakho evamile yansuku zonke noma isimiso sokuzivocavoca okungenani izinsuku ezintathu . Ungazibandakanyi ngokuzumayo ekuzivocavoceni okunzima ngaphambi kokuhlolwa.
• Kuzodingeka uzile ukudla ngaphambi kokuhlolwa – lokhu kusho ukuthi awukwazi ukudla noma ukuphuza noma yini ngaphandle kwamanzi okungenani amahora angu-8 (mhlawumbe nangaphezulu).
• Awukwazi ukudla noma ukubhema phakathi nokuhlolwa konke .

Udokotela wakho uzokunikeza imiyalelo ecacile yokuthi yini okufanele uyenze ngokusekelwe esimweni sakho kanye nohlobo lwe-GTT onayo. Kubaluleke kakhulu ukuyilandela ngqo. Uma unemibuzo noma ungaqondi okuthile, ungangabazi ukubuza udokotela wakho, kulungile?

Kwenzekani ngosuku lwe-`(GTT)`?

Sesixoxile kakade ukuthi indlela i-`(GTT)` eyenziwa ngayo ingahluka kuye ngohlobo lokuhlolwa. Ake sithathe isibonelo sendlela okwenziwa ngayo okuvame kakhulu amahora amabili `(Oral Glucose Tolerance Test - OGTT)`.

Esikhathini esiningi, lokhu kuhlolwa kuqala ekuseni, ngokuvamile phakathi kuka-7:00 no-9:00 ekuseni. Njengoba uzobe usesibhedlela noma esikhungweni sezokwelapha kuze kube yilapho ukuhlolwa kuphelile, kuwukuhlakanipha ukuletha okuthile okuzokugcina umatasa, njengencwadi noma incwadi yamanothi.

Lezi yizinyathelo ezivame ukwenzeka:

1. Okokuqala, udokotela noma udokotela we-phlebotomist uzothatha isampula yegazi emthanjeni wakho. Lokhu kusetshenziselwa ukukala izinga lakho likashukela egazini lokuzila ukudla.

2. Ngemuva kwalokho, uzonikezwa isisombululo esikhethekile se-glucose ukuze usiphuze. Ngokuvamile lokhu kuqukethe cishe amagremu angu-75 e-glucose encibilikiswe emanzini angamamililitha angu-250-300. Uzoyalwa ukuba uphuze lonke leli sixazululo kungakapheli imizuzu emihlanu.Kodwa-ke, inani le-glucose elinikezwa izingane ezincane kanye nomama abakhulelwe lingahluka. Lesi sixazululo se-glucose simnandi kakhulu, njenge-Gatorade emnandi. Abanye abantu bangase bathole ukunambitheka kwayo kungathandeki kancane.

3. Ngemva kwamahora amabili nje uphuze isisombululo se-glucose, kuzothathwa elinye isampula yegazi emthanjeni wakho ukuze kuhlolwe izinga le-glucose egazini lakho. Kuye ngesizathu sokuhlolwa, igazi lingathathwa njalo ngemizuzu engama-30, kanye ngehora, noma izikhathi eziningana ngemva kokuphuza isisombululo se-glucose.

Ingabe zikhona ezinye izinhlobo ze-`(GTT)`?

Yebo, kunezinhlobo eziningana ze-`(GTT)` ezenzelwe izidingo ezahlukene. Ake sibheke izibonelo ezimbalwa:

• Ukuhlolwa kokubekezelela ushukela wehora elilodwa: Lokhu kuvame ukwenziwa ukuhlola isifo sikashukela sokukhulelwa. Uphuza uketshezi oluqukethe amagremu angu-50 eglucose, bese kuthi izinga likashukela egazini lakho likalwe ngemva kwehora elilodwa. Lokhu kuhlolwa ngokuvamile akudingi ukuzila ukudla.
• Ukuhlolwa kokubekezelela ushukela kwamahora amathathu: Kulokhu kuhlolwa, igazi lithathwa ngaphambi kokuphuza isisombululo se-glucose (ngemuva kokuzila ukudla). Bese, amasampula egazi athathwa futhi ihora elilodwa, amahora amabili, kanye namahora amathathu ngemva kokuphuza isisombululo se-glucose.
• Ukuhlolwa kokubekezelela i-glucose kwe-acromegaly: Kulolu vivinyo, udokotela wakho uthatha isampula yegazi hhayi ukuze ahlole izinga likashukela egazini lakho, kodwa ukuze ahlole amazinga akho e-hormone yokukhula komuntu (i-HGH). Ngemva kokuphuza isisombululo se-glucose, igazi lakho lingadonswa njalo ngemizuzu engama-30 amahora amabili (okungukuthi, ngemizuzu engama-30, engama-60, engama-90, kanye neyi-120).

Yini ongayilindela ngemva kokuphela kokuhlolwa?

Ngemva kwe-GTT, ungaqala imisebenzi yakho yansuku zonke njengenjwayelo. Ungaqala futhi ukudla futhi. Kungaba ngumqondo omuhle ukuletha ukudla okulula ozokudla ngemva kokuhlolwa. Udokotela wakho uzokutshela uma kukhona imiyalelo ekhethekile, futhi uzokwazisa nokuthi imiphumela izotholakala nini.

Kuthatha isikhathi esingakanani ukwazi imiphumela yokuhlolwa?

Ezimweni eziningi, uzokwazi ukuthola imiphumela ye-"GTT" zingakapheli izinsuku ezimbalwa zokusebenza. Kodwa-ke, lesi sikhathi singahluka kancane kuye ngelebhu. Ngakho ungakhathazeki.

Ingabe kukhona imiphumela emibi evela kulokhu `(GTT)`?

Ukuhlolwa kokubekezelela ushukela ngokuvamile kuyindlela ephephile kakhulu . Iningi labantu alizizwa lingakhululekile ngemva kokuphuza isisombululo se-glucose. Kodwa-ke, abanye abantu bangase bazizwe benesicanucanu noma benesiyezi. Kodwa-ke, imiphumela emibi emibi ayivamile.

Ukukhipha igazi kuyingxenye evamile kakhulu futhi edingekayo yokuhlolwa kwezokwelapha. Akuvezi zingozi ezinkulu. Ungase uzizwe ubuhlungu noma ulimale kancane, kodwa kuzophola ngokushesha.

Imiphumela ye-`(GTT)` ithini ngempela?

Umbiko wakho wemiphumela ye-GTT uzokhombisa izinga likashukela egazini njalo lapho igazi lakho likhishwa. ESri Lanka, ushukela egazini uvame ukulinganiswa ngama-milligram nge-deciliter (mg/dL).

Amazinga asetshenziswa amalabhorethri ahlukene kanye nodokotela ukuxilonga izinkinga zikashukela egazini njengesifo sikashukela angahluka kancane, ngakho-ke bheka njalo uhla lwezinkomba olunikezwe embikweni wakho wemiphumela.

Ngokuvamile, odokotela basebenzisa la mazinga amanani e-OGTT yamahora amabili:

• Okuvamile: Ngaphansi kuka-140 mg/dL.
• I-Prediabetes: Phakathi kuka-140 mg/dL no-199 mg/dL.
• Isifo sikashukela: 200 mg/dL noma ngaphezulu.

Lezi zindinganiso kanye nezikhawu zokuthatha amasampula egazi zingahluka kwezinye izimo, njengesifo sikashukela sokukhulelwa kanye ne-acromegaly. Isibonelo, ukuhlolwa kwe-growth hormone (GTT) ukuhlola i-acromegaly kuhlola izinguquko emazingeni e-growth hormone. Udokotela wakho uzoxoxa nawe ngale miphumela ngokuningiliziwe.

Uma imiphumela ingajwayelekile, kuzokwenzekani ngokulandelayo?

Cabanga nje, kuzokwenzekani ngokulandelayo uma imiphumela yakho ye-`(GTT)` ingavamile, okungukuthi, 'engavamile'. Ungakhathazeki, udokotela wakho uzokutshela ngokucacile ukuthi yiziphi izinyathelo okufanele uzithathe ngokulandelayo. Yiqiniso, kuvamile ukuzizwa ukhathazekile futhi wesaba kancane lapho umphumela ungavamile. Kodwa yazi lokhu, odokotela abanqumi ngokushesha ukuthi une-`prediabetes` noma `isifo sikashukela` ngoba nje umphumela owodwa we-`(OGTT)` awujwayelekile.

Cishe kuzodingeka uphinde wenze isivivinyo esifanayo ezinsukwini ezimbalwa, noma udokotela wakho angase acele olunye isivivinyo sokuxilonga, njengokuhlolwa kwe-A1C. Kodwa-ke, udokotela wakho uzoba nawe kuyo yonke inqubo yokuxilonga. Unganqikazi ukubuza noma yimiphi imibuzo onayo futhi ukhulume ngezinto ezikukhathazayo.

Kuvamile ukuzizwa wesaba uma ubona umphumela wokuhlolwa ongajwayelekile. Kodwa khumbula, umphumela we-GTT ongajwayelekile akusho ukuthi unesifo sikashukela. Uma imiphumela ibonisa ukuthi ushukela wakho wegazi uphezulu, udokotela wakho cishe uzokwenza ezinye izivivinyo ukuze athole ukuxilongwa okuqondile. Ungesabi ukubuza udokotela wakho imibuzo. Bakhona ukukusiza.

Izinto ezibaluleke kakhulu okufanele sizithathe ekhaya kule ndaba

Ngakho-ke, i-Glucose Tolerance Test (GTT) esikhulume ngayo namuhla iyisivivinyo sezokwelapha esibaluleke kakhulu esisisiza sazi kahle ukuthi umzimba wethu usebenzisa futhi ugcina kanjani ushukela, okungukuthi, i-glucose. Lokhu kusiza kakhulu ekutholeni izifo ezinjengoshukela kusenesikhathi.

Kunokulungiselela okuncane ngaphambi kokuhlolwa, futhi ukukulandela kubaluleke kakhulu ukuze uthole imiphumela enembile. Ngesikhathi sokuhlolwa, uzophuza uketshezi olushukela olumnandi, bese kuthi amasampula egazi athathwe izikhathi eziningana emahoreni ambalwa.

Into ebaluleke kakhulu ukungesabi, kungakhathaliseki ukuthi imiphumela injani . Ngisho noma imiphumela ingavamile, akusikho ukuphela komhlaba. Khuluma nodokotela wakho ngokucophelela bese uthola ukuthi yini okufanele uyenze ngokulandelayo. Khumbula, ukutholakala kusenesikhathi kanye nokwelashwa kwezimo zezokwelapha kuyindlela engcono kakhulu yokuphila impilo enempilo nejabulisayo! Uma unemibuzo, ungangabazi ukukhuluma nodokotela.
