Umzimba wakho ulawula kakuhle kangakanani iswekile? Masifunde ngovavanyo lokunyamezela iswekile (GTT) ngendlela elula!

Ngaba wakha weva ngovavanyo lokunyamezela iswekile, okanye i-GTT ngamafutshane? Ugqirha wakho usenokuba ukuxelele ngalo, okanye usenokuba ucele ukuba lwenziwe. Olu luvavanyo olubaluleke kakhulu olujonga ukuba umzimba wakho usebenzisa kwaye ugcina iswekile, okanye iswekile. Oogqirha badla ngokusebenzisa olu vavanyo ukuxilonga iimeko ezifana nesifo seswekile. Kodwa kukho ezinye iindlela zokuxilonga isifo seswekile, njengovavanyo lwe-A1C kunye novavanyo lweswekile yegazi lokuzila ukutya.

Ngoko ke, yintoni le test yokunyamezelana neglucose (`GTT`)?

Ngamafutshane, imizimba yethu ifumana amandla ayo ekutyeni esikutyayo, ingakumbi ukutya okuneekhabhohayidreyithi ezininzi. Yile nto enika iiseli zethu amandla okusebenza. Imizimba yethu ikwagcina le glucose ukuze isetyenziswe kamva, ikakhulu kwimisipha yethu nakwisibindi. Le glucose igciniweyo ibizwa ngokuba yi-glycogen.

Ngoko ke, ukuze sigcine inqanaba leglucose egazini lethu likwinqanaba elithile, iinkqubo ezahlukeneyo zenzeka ngaphakathi emzimbeni wethu. Phakathi kwazo , ihomoni ebizwa ngokuba yi-insulin idlala indima ephambili . Le insulin iveliswa kwi-pancreas yethu. Ukuba kukho nayiphi na ingxaki kwindlela umzimba wethu osebenzisa ngayo iglucose, inqanaba leswekile egazini linokunyuswa rhoqo. Yiloo nto siyibiza ngokuba yi-hyperglycemia. Kwakhona, ngamanye amaxesha inqanaba leswekile egazini linokwehla, kwaye loo meko ibizwa ngokuba yi-hypoglycemia.

Kukho iintlobo ezahlukeneyo ze-GTT. Eyona isetyenziswa kakhulu yi-Oral Glucose Tolerance Test (OGTT), equka ukunika isisombululo seglucose ngomlomo.

Kuqhelekile ukuba novalo ngaphambi kokuba wenze naluphi na uvavanyo lwezonyango. Kodwa khumbula, eyona nto ibalulekileyo kukwazi. Nokuba iziphumo zithini na, uza kufunda okungakumbi ngomzimba wakho kunokuba wawusazi ngaphambili. Ngolo lwazi, wena nogqirha wakho ninokwenza isicwangciso esingcono sempilo yenu kwixesha elizayo.

Kuphantsi kweziphi iimeko apho kuya kufuneka wenze oku `(GTT)`?

Ugqirha wakho unokucebisa i-GTT ukujonga okanye ukuqinisekisa ukuba kukho nayiphi na kwezi meko zilandelayo:

• Isifo seswekile – sidla ngokuba sisifo sangaphambi kwesifo seswekile, isifo seswekile sohlobo lwesibini, okanye isifo seswekile sokukhulelwa.
• Imeko ebizwa ngokuba yi-insulin resistance.
• I-hypoglycemia ekhawulezayo - Oku kukwehla kwamanqanaba eswekile egazini emva kokutya.
• I-Acromegaly yimeko yehomoni.
• Iingxaki ezingaqhelekanga zemetabolism ye-carbohydrate.

Kodwa khumbula ukuba kukho ezinye iimvavanyo ezinokusetyenziswa ukuxilonga ezi meko. Ugqirha wakho unokuyalela uvavanyo olungaphezulu kolunye.

Ingakumbi ngexesha lokukhulelwa, uvavanyo lwe-glucose challenge lweyure enye ludla ngokwenziwa ukujonga isifo seswekile sokukhulelwa . Ukuba iziphumo aziqhelekanga, ugqirha wakho unokuyalela uvavanyo lokunyamezela i-glucose ngomlomo (OGTT) lweeyure ezintathu ukuqinisekisa ukuxilongwa okanye ukuthintela imeko.

Ubani ufanele azilungiselele njani `(GTT)`?

Ekubeni kukho iintlobo ezahlukeneyo ze-GTT, kunokubakho utshintsho oluncinci kwindlela ekufuneka uzilungiselele ngayo kuxhomekeke kuvavanyo olulwenzayo. Kodwa ngokubanzi, nazi izinto ekufuneka uzenze:

• Ufanele uxelele ugqirha wakho ngawo onke amayeza kunye nezongezo ozisebenzisayo, kuba amanye amayeza anokuchaphazela iziphumo zovavanyo. Ugqirha wakho angakucela ukuba uyeke ukusebenzisa amayeza athile kwiintsuku ezimbalwa ngaphambi kovavanyo.
• Ufanele utye ngokwesiqhelo ubuncinane iintsuku ezintathu ngaphambi kovavanyo. Kubalulekile ukutya ukutya okune-150 grams yeecarbohydrates ngosuku.
• Musa ukutshintsha imisebenzi yakho yemihla ngemihla okanye indlela oqhele ukuzilolonga ngayo ubuncinane iintsuku ezintathu . Musa ukuzilolonga nzima ngequbuliso ngaphambi kovavanyo.
• Kuya kufuneka uzile ukutya ngaphambi kovavanyo – oku kuthetha ukuba awunakutya okanye usele nantoni na ngaphandle kwamanzi ubuncinane iiyure ezisi-8 (mhlawumbi nangaphezulu).
• Akunakutya okanye ukutshaya ngexesha lonke lovavanyo.

Ugqirha wakho uza kukunika imiyalelo ecacileyo malunga nento omawuyenze ngokusekwe kwimeko yakho kunye nohlobo lwe-GTT onayo. Kubaluleke kakhulu ukuyilandela ngqo. Ukuba unemibuzo okanye awuqondi into ethile, ungathandabuzi ukubuza ugqirha wakho, kulungile?

Kwenzeka ntoni ngomhla we-`(GTT)`?

Sele sixoxe ngokuba indlela eyenziwa ngayo i-`(GTT)` inokwahluka ngokuxhomekeke kuhlobo lovavanyo. Makhe sithathe umzekelo wendlela eyenziwa ngayo i-`(Oral Glucose Tolerance Test - OGTT)` eqhele ukwenziwa ngayo iiyure ezimbini.

Uninzi lwexesha, olu vavanyo luqala kusasa, ngesiqhelo phakathi kwentsimbi yesi-7:00 nentsimbi yesi-9:00 kusasa. Ekubeni uza kuba sesibhedlele okanye kwiziko lezonyango de uvavanyo luphele, kububulumko ukuzisa into eza kukugcina uxakekile, njengencwadi okanye incwadi yamanqaku.

La manyathelo adla ngokwenzeka:

1. Okokuqala, ugqirha okanye ingcali ye-phlebotomist iza kuthatha isampuli yegazi emthanjeni wakho. Oku kusetyenziswa ukulinganisa inqanaba le-glucose egazini lakho lokuzila ukutya.

2. Emva koko, uza kunikwa isisombululo esikhethekileyo seglucose ukuze usisele. Esi siqhelo siqulathe malunga neegram ezingama-75 zeglucose enyibilikiswe kwi-250-300 milliliters zamanzi. Uza kuyalelwa ukuba usele sonke esi sisombululo kwimizuzu emihlanu.Nangona kunjalo, ubungakanani beglucose enikwa abantwana abancinci kunye noomama abakhulelweyo bunokwahluka. Esi sicombululo seglucose simnandi kakhulu, njengeGatorade eswiti. Abanye abantu banokuyifumana incasa ingathandekiyo kancinci.

3. Emva kweeyure ezimbini emva kokusela isisombululo seglucose, kuya kuthathwa esinye isampuli yegazi emthanjeni wakho ukuze kuhlolwe inqanaba leglucose egazini lakho. Ngokuxhomekeke kwisizathu sovavanyo, igazi linokuthatyathwa rhoqo emva kwemizuzu engama-30, kube kanye ngeyure, okanye amaxesha amaninzi emva kokusela isisombululo seglucose.

Ngaba kukho ezinye iinguqulelo ze-`(GTT)`?

Ewe, kukho iintlobo ezahlukeneyo ze-`(GTT)` ezenzelwe iimfuno ezahlukeneyo. Makhe sijonge imizekelo embalwa:

• Uvavanyo lokunyamezela iswekile egazini oluthatha iyure enye: Oku kudla ngokwenziwa ukuze kuhlolwe isifo seswekile sokukhulelwa. Usela ulwelo olune-50 grams yeswekile egazini, uze emva koko ulinganise inqanaba leswekile egazini lakho emva kweyure. Olu vavanyo aludingi kuzila ukutya.
• Uvavanyo lokunyamezela i-glucose lweeyure ezintathu: Kolu vavanyo, igazi lithathwa ngaphambi kokuba kuphungwe isisombululo se-glucose (emva kokuzila ukutya). Emva koko, iisampuli zegazi zithathwa kwakhona emva kweyure enye, iiyure ezimbini, kunye neeyure ezintathu emva kokusela isisombululo se-glucose.
• Uvavanyo lokunyamezela i-glucose kwi-acromegaly: Kolu vavanyo, ugqirha wakho uthatha isampuli yegazi kungekhona ukujonga inqanaba leswekile egazini lakho, kodwa ukujonga amanqanaba akho e-human growth hormone (HGH). Emva kokuba usele isisombululo se-glucose, igazi lakho linokuthathwa rhoqo emva kwemizuzu engama-30 kangangeeyure ezimbini (oko kukuthi, kwimizuzu engama-30, engama-60, engama-90, nengama-120).

Yintoni onokuyilindela emva kokuba uvavanyo luphelile?

Emva kwe-GTT, ungenza imisebenzi yakho yemihla ngemihla njengesiqhelo. Ungaqala nokutya kwakhona. Kungaba licebo elihle ukuzisa i-snack emva kovavanyo. Ugqirha wakho uza kukuxelela ukuba kukho nayiphi na imiyalelo ekhethekileyo, aze akwazise nokuba iziphumo ziya kufumaneka nini.

Kuthatha ixesha elingakanani ukwazi iziphumo zovavanyo?

Kwiimeko ezininzi, uya kukwazi ukufumana iziphumo ze-"GTT" kwiintsuku ezimbalwa zokusebenza. Nangona kunjalo, eli xesha linokwahluka kancinci kwilabhoratri nganye. Ngoko ungakhathazeki.

Ngaba kukho naziphi na iziphumo ebezingalindelekanga ezivela kule `(GTT)`?

Uvavanyo lokunyamezela i-glucose luvavanyo olukhuselekileyo . Uninzi lwabantu aluziva lungonwabanga emva kokusela isisombululo se-glucose. Nangona kunjalo, abanye abantu banokuziva benesicaphucaphu okanye bedidekile. Nangona kunjalo, iziphumo ebezingalindelekanga ezibi azixhaphakanga.

Ukutsalwa kwegazi yinxalenye eqhelekileyo neyimfuneko yovavanyo lwezonyango. Akuzibeki mngcipheko mkhulu. Usenokuziva unesilonda okanye unesilonda esincinci, kodwa ziya kuphola ngokukhawuleza.

Zithini ngokwenene iziphumo ze-`(GTT)`?

Ingxelo yeziphumo zakho ze-GTT iya kubonisa inqanaba leswekile egazini ngalo lonke ixesha igazi lakho litsalwa. ESri Lanka, iswekile egazini idla ngokulinganiswa ngeemiligrama ngedesilitha nganye (mg/dL).

Uluhlu olusetyenziswa ziilabhoratri ezahlukeneyo kunye noogqirha ukuxilonga iingxaki zeswekile yegazi ezifana nesifo seswekile lunokwahluka kancinci, ngoko ke soloko ubhekisa kuluhlu lweereferensi olunikiweyo kwingxelo yeziphumo zakho.

Ngokubanzi, oogqirha basebenzisa la manqanaba amaxabiso kwi-OGTT yeeyure ezimbini:

• Eqhelekileyo: Ngaphantsi kwe-140 mg/dL.
• I-Prediabetes: Phakathi kwe-140 mg/dL kunye ne-199 mg/dL.
• Isifo seswekile: 200 mg/dL okanye ngaphezulu.

La maxabiso kunye nexesha lokuthathwa kweesampuli zegazi linokwahluka kwezinye iimeko, ezifana nesifo seswekile sokukhulelwa kunye ne-acromegaly. Umzekelo, uvavanyo lwehomoni yokukhula (GTT) lokujonga i-acromegaly luvavanya utshintsho kumanqanaba ehomoni yokukhula. Ugqirha wakho uza kuxoxa nawe ngezi ziphumo ngokweenkcukacha.

Ukuba iziphumo aziqhelekanga, kuza kwenzeka ntoni emva koko?

Khawucinge nje, kuya kwenzeka ntoni emva koko ukuba iziphumo zakho ze-`(GTT)` aziqhelekanga, oko kukuthi, 'ezingaqhelekanga'. Ungakhathazeki, ugqirha wakho uya kukuxelela ngokucacileyo ukuba zeziphi amanyathelo omawuwathathe ngokulandelayo. Yinyani, kuqhelekile ukuba uzive ukhathazekile kwaye usoyika xa iziphumo zingaqhelekanga. Kodwa yazi oku, oogqirha abagqibi kwangoko ukuba une-`prediabetes` okanye `diabetes` kuba nje isiphumo esinye se-`(OGTT)` singaqhelekanga.

Kusenokufuneka uphinde wenze uvavanyo olufanayo kwiintsuku ezimbalwa, okanye ugqirha wakho angayalela olunye uvavanyo lokuxilonga, njengovavanyo lwe-A1C. Nangona kunjalo, ugqirha wakho uya kuba nawe kuyo yonke inkqubo yokuxilonga. Musa ukuthandabuza ukubuza nayiphi na imibuzo onayo kwaye uthethe ngezinto ezikuxhalabisayo.

Kuqhelekile ukuba noloyiko xa ubona iziphumo zovavanyo ezingaqhelekanga. Kodwa khumbula, iziphumo ze-GTT ezingaqhelekanga akuthethi ukuba unesifo seswekile.
