Ngaba ugqirha wakho wakha wakucela ukuba usele ulwelo oluneswekile uze uvavanye igazi? Abantu abaninzi bayazibuza ukuba yintoni le nto kwaye kutheni isenziwa, mhlawumbi bade bazive besoyika kancinci. Kodwa eneneni akukho nto yokoyika. Olu luvavanyo oluqhelekileyo olwenziwayo ukuze kufunyanwe ulwazi olubalulekileyo malunga nempilo yakho. Ke namhlanje, masithethe ngolu Vavanyo Lokunyamezela Iswekile Yomlomo, okanye i-OGTT njengoko sonke sisazi.
Yintoni le OGTT?
Ngamafutshane, i-OGTT luvavanyo olulinganisa indlela umzimba wakho olawula ngayo i-glucose evela kumthombo wamandla. Oku kunokunika ugqirha wakho izikhokelo ezibalulekileyo malunga nempilo yakho.
Xa sisitya, amanqanaba eswekile egazini lethu adla ngokunyuka. Emva koko, i-gland ebizwa ngokuba yi-pancreas, ekwisisu sethu, ivelisa i-hormone ebizwa ngokuba yi-insulin . Cinga ngeeseli zomzimba wakho njengezindlu ezincinci. Iswekile oyifumana ekutyeni okutyayo ngamandla afunekayo kwezi zindlu. Ngoko ke, i-insulin ifana nesitshixo esithatha le swekile, sivule iingcango zezindlu, size sivumele iswekile ingene. Xa iswekile ingena kwiiseli, amanqanaba eswekile egazini abuyela kwisiqhelo.
Nangona kunjalo, ukuba unesifo seswekile sohlobo lwesibini, umzimba wakho awusisebenzisi kakuhle esi sitshixo sibizwa ngokuba yi-insulin. Emva koko iswekile iqokelelana egazini endaweni yokungena kwiiseli. Le swekile ingaphezulu egazini inokonakalisa imithambo yegazi emzimbeni wonke. Iswekile inokubangela isifo sentliziyo, umonakalo wemithambo-luvo, isifo samehlo, kunye nesifo sezintso.
Ngoko ke uvavanyo lwe-OGTT lujonga ikakhulu ukuba usemngciphekweni wokuba nesifo seswekile, okanye ukuba sele unesifo seswekile. Uvavanyo olufutshane lwe-OGTT ngexesha lokukhulelwa lunokufumanisa ukuba unesifo seswekile sokukhulelwa.
Ngubani ocelwa ukuba enze olu vavanyo lwe-OGTT?
Ukuba unenye okanye ngaphezulu kwezi zinto zilandelayo ezibangela umngcipheko, ugqirha wakho unokukucela ukuba wenze uvavanyo lwe-OGTT.
| Into enobungozi | Inkcazo |
|---|---|
| Ukutyeba kwakho | Ukuba umzimba wakho utyebile/utyebile kakhulu. |
| Imbali yosapho | Ukuba kukho umntu kusapho lwakho olusondeleyo (umama, utata, abantakwenu noodadewabo) onesifo seswekile. |
| Igazi elonyukayo | Ukuba une-high blood pressure. |
| Ii-triglycerides eziphezulu | Ukuba unezinga eliphezulu lamafutha abizwa ngokuba yi-triglycerides egazini lakho. |
| Imeko ye-PCOS | Ukuba unesifo esibizwa ngokuba yiPolycystic Ovary Syndrome (PCOS), esibangela iingxaki kumjikelo wakho wokuya exesheni. |
| Imeko yangaphambi kokukhulelwa | Ukuba ubelethe umntwana onobunzima obungaphezulu kweekhilogram ezili-10 (malunga neekhilogram ezi-4) okanye ukuba unesifo seswekile sokukhulelwa ngexesha lokukhulelwa kwangaphambili. |
Ngaba i-OGTT yahlukile ngexesha lokukhulelwa?
Ewe, ukuba ukhulelwe, kuya kufuneka ube novavanyo olufutshane lwe-OGTT phakathi kweeveki ezingama-24 nezingama-28 zokukhulelwa. Olu vavanyo lweyure enye lubizwa ngokuba 'luvavanyo lwe-glucose challenge'.
Nangona kunjalo, ukuba usemngciphekweni omkhulu wokuba nesifo seswekile sokukhulelwa, ugqirha wakho unokucebisa ukuba wenze olu vavanyo kwangethuba. Ezi zinto ziquka:
- Ukuba wayenesifo seswekile sokukhulelwa ngaphambili.
- Ukuba nesifo seswekile kusapho.
- Ukutyeba kakhulu.
- Ukuba nenye imeko yezonyango eyonyusa umngcipheko wesifo seswekile, njenge-PCOS.
Ukuba ugqirha wakho ukhathazekile ngengozi yakho, okanye ukuba iziphumo zovavanyo lweyure enye ziphezulu, unokucelwa ukuba wenze uvavanyo lwe-OGTT olude oluhlala iiyure ezi-3.
Ulungiselela njani ngaphambi kovavanyo?
Ukulungiselela oku kulula kakhulu.
- Kwiintsuku ezimbalwa ngaphambi kovavanyo, yitya ngendlela eqhelekileyo. Musa ukutya ukutya okukhethekileyo.
- Akunakutya okanye kusela nantoni na kangangeeyure ezisi-8 ngaphambi kovavanyo. Elona xesha lilungileyo lokwenza oku kukucwangcisa uvavanyo kusasa. Emva koko ungazila ukutya ubusuku bonke.
- Ngeli xesha leeyure ezisi-8 , uvumelekile ukusela amanzi kuphela. Musa ukusela naziphi na ezinye iziselo.
- Thetha nogqirha wakho malunga neminye imithi oyithathayo xa ucwangcisa uvavanyo lwakho.
Indlela yokwenza uvavanyo inyathelo ngenyathelo
Ungenza olu vavanyo lwe-OGTT eofisini kagqirha wakho, ekliniki, esibhedlele, okanye elebhu.
1. Okokuqala, kuya kuthathwa isampuli yegazi ukujonga inqanaba le-glucose egazini lakho lokuzila ukutya.
2. Emva koko uza kunikwa iglasi enkulu yolwelo oluneswekile ukuze ulusele.
3. Okulandelayo, kuya kufuneka ulinde okwethutyana. Ngeli xesha, awunakuphuma kwilabhoratri okanye kwikliniki.
4. Ukuba wenza uvavanyo lwesifo seswekile rhoqo , uza kusela isinyibiliko seswekile uze emva koko uthathe esinye isampuli yegazi emva kweeyure ezimbini .
5. Ukuba wenza uvavanyo lwesifo seswekile sokukhulelwa (iiyure ezi-3) , uza kusela isisombululo seswekile kwaye uthathwe iisampuli zegazi kwiyure e-1, iiyure ezi-2, kunye neeyure ezi-3 .
Emva kokuba uvavanyo luphelile, ungabuyela kwimisebenzi yakho yesiqhelo.
Ngaba kukho naziphi na iingozi ngolu vavanyo?
Uvavanyo lwe-OGTT luvavanyo olukhuselekileyo kakhulu, kodwa abanye abantu banokufumana iziphumo ebezingalindelekanga ezincinci.
Izinto ezinokwenzeka ngenxa yeziselo ezineswekile:
- Isicaphucaphu
- Ukuhlanza
- Ukuzalisa isisu
- Intloko ebuhlungu
- Amanqanaba eswekile egazini aphantsi (anqabile kakhulu)
Izinto ezinokwenzeka ngenxa yokunikela ngegazi:
- Ukopha kakhulu
- Isiyezi
- Imeko yosulelo
- Intlungu encinci evela kwimizamo ephindaphindiweyo yokufumana umthambo wegazi
- Ukugruzuka okanye iintlungu kwindawo yolunywa
Ezi zizinto ezincinci kakhulu kwaye ziya kuphola ngokukhawuleza.
Zithini iziphumo?
Emva kokuba usele isiselo esineswekile, inqanaba leswekile egazini lakho liyanyuka kwaye kufuneka libuyele esiqhelweni emva kwexesha elithile ngenxa yesenzo sehomoni ye-insulin. Ukuba kuthatha ixesha elide ukubuyela esiqhelweni, isenokuba luphawu lwesifo seswekile. Iziphumo kwingxelo yakho zichazwe ngo-"mg/dL" (ii-milligrams nge-deciliter nganye).
| Inqanaba leswekile egazini (mg/dL) | Intsingiselo |
|---|---|
| Ukuhlolwa kwesifo seswekile rhoqo (i-OGTT yeeyure ezi-2) | |
| 139 mg/dL okanye ngaphantsi | Isiqhelo : Umzimba wakho ulawula iswekile kakuhle. |
| Phakathi kwe-140 mg/dL kunye ne-199 mg/dL | I-Prediabetes : Usengozini enkulu yokuba nesifo seswekile. |
| 200 mg/dL okanye ngaphezulu | Isifo seswekile . Usenokuba unesifo seswekile. |
| Ukuhlolwa kwesifo seswekile sokukhulelwa (i-OGTT yeeyure ezi-3) | |
| Ukuzila ukutya | Ifanele ibe ngaphantsi kwe-95 mg/dL . |
| Emva kweyure e-1 | Ifanele ibe ngaphantsi kwe-180 mg/dL . |
| Emva kweeyure ezi-2 | Ifanele ibe ngaphantsi kwe-155 mg/dL . |
| Emva kweeyure ezi-3 | Ifanele ibe ngaphantsi kwe-140 mg/dL . |
I-prediabetes ithetha ukuba usengozini enkulu yokuba nesifo seswekile. Kufana nomqondiso wesilumkiso. Ukuba wenza utshintsho kwindlela ophila ngayo ngeli xesha, ungenza lukhulu ekuthinteleni isifo seswekile.
Ukuba umfazi okhulelweyo unesinye seziphumo ezingentla eziphezulu kunesiqhelo, ugqirha wakhe uya kumcebisa ukuba aphinde avavanywe kwiiveki ezimbalwa. Ukuba iziphumo ezimbini nangaphezulu ziphezulu, ufunyaniswa ukuba unesifo seswekile sokukhulelwa.
Kwenzeka ntoni emva kovavanyo?
Ugqirha wakho uza kukuchazela into omawuyenze ngokulandelayo ngokusekelwe kwiziphumo.
- Ukuba une-prediabetes: Ugqirha wakho uza kuthetha nawe ngeendlela zokuthintela ukuba ingabi sisifo seswekile. Ukuzilolonga kunye nokunciphisa umzimba zezona ndlela zimbini zibalaseleyo zokunciphisa umngcipheko wakho wesifo seswekile.
- Ukuba unesifo seswekile: Usenokucelwa ukuba wenze ezinye iimvavanyo, ezifana ne-A1c, ukuqinisekisa ukuba unesifo. Ukutya okunempilo, umthambo, kunye namayeza kunokunceda ukulawula amanqanaba eswekile egazini lakho.
- Ukuba unesifo seswekile sokukhulelwa: Ungayilawula le meko ngokutya ukutya okunempilo nokuzilolonga. Amanqanaba eswekile yakho egazini kufuneka abuyele kwisiqhelo emva kokuba uzele umntwana wakho. Nangona kunjalo, umntu onesifo seswekile sokukhulelwa usemngciphekweni omkhulu wokufumana isifo seswekile sohlobo lwesibini kwixesha elizayo. Yiyo loo nto kubalulekile ukuqhubeka nokugcina indlela yokuphila esempilweni.
Eyona nto ibalulekileyo kukuthetha nogqirha wakho ngayo yonke le nto uze ulandele imiyalelo yakhe ngokuchanekileyo.
Umyalezo Wokuya Ekhaya
- I-OGTT luvavanyo olubalulekileyo olujonga indlela umzimba wakho oyisebenzisa ngayo iswekile.
- Oku kunokunceda ekuxilongeni isifo seswekile kunye nesifo seswekile sokukhulelwa.
- Kuyimfuneko ukuzila ukutya iiyure ezisi-8 ngaphambi kovavanyo.
- Ngokusekelwe kwiziphumo, ugqirha wakho uza kukunika icebiso elifanelekileyo.
- Olu luvavanyo olukhuselekileyo olunengozi encinci kakhulu, ngoko ke musa ukuloyika.
