Ngemuva kokuphothula uchungechunge lwezifundo, ososayensi bafika eziphethweni ezidumazayo: uhlobo 2 sikashukela, olutholakala ebusheni, lukhulisa ubungozi empilweni. Sikhuluma ngamathuba anyuswe angama-60% okufa kwesifo senhliziyo, kanye nengozi engama-30% yokufa kusuka kunoma yisiphi isizathu ngokujwayelekile. Kepha amathuba okufa komdlavuza ezigulini ezinje aphansi kakhulu kunokujwayelekile, bayasho.
"Isifo sikashukela sohlobo 2 kubantu abasha sikhula ngokuhlukumezeka futhi siholele ekufeni kwabantu abaningi," kusho umlobi we-cwaningo uDianna Magliano, inhloko ye-laboratory e-Baker Institute for Heart and Diabetes eMelbourne.
Kungani lokhu kwenzeka? Ngokunokwenzeka, ngoba abantu abasha baphila isikhathi esingaphezu konyaka noshukela wegazi ophakeme kanye nezinkinga ezihlobene.
UDkt Joel Zonszine, umphathi weClinical Center for Diabetes eMontefiore Medical Center eNew York, akazange abambe iqhaza kulolu cwaningo, kodwa futhi uthi emashumini eminyaka adlule, uhlobo lwesifo sikashukela selushintshe kakhulu, unolaka kakhulu futhi waqala ukukhula cishe nanganoma ikuphi ubudala, kodwa ngaphambili wabizwa ngokuthi isifo sabadala.
"Kuhlobo lwayo lwamanje, isifo sikashukela sohlobo 2 sidala izinkinga ezikhuluphele ngokweqile kanye ne-lipotoxicity (lokhu ukuqongelela kwe-cholesterol lapho kufanele kungabi khona - esibindini, izinso noma inhliziyo), ukuzwela kwe-insulin, ukuvela okuningi, nakho konke lokhu kubangela isifo senhliziyo ngaphambi kwesikhathi, ”kusho uDkt Zonszain.
Ephawula ngemininingwane mayelana nengozi encishisiwe yokuthola umdlavuza, uZonszain uphawula ukuthi umdlavuza uvama ukukhula kancane futhi umane ungatholakali kuze kube yilapho abantu sebekhulile. Ubuye wengeza ukuthi ukukhuluphala, okuhambisana nesifo sikashukela sohlobo 2, futhi kubangela ukukhula kwenamba enkulu yomdlavuza, ukuze, ngokubona kwakhe, okutholakele ocwaningweni lokuthi amacala okuqala esifo sikashukela sohlobo 2 mancane kakhulu amathuba okuba nomdlavuza.
Mhlawumbe iqiniso lokuthi iziguli ezisencane ezinesifo sikashukela zinokufa okungajwayelekile okuvela kumdlavuza kungenxa yokuthi lesi sifo sivame ukuvela ekugugeni. Kukhona futhi ukuthi njengoba abantu abanesifo sikashukela kufanele bahlolwe njalo, bazothola umdlavuza kusenesikhathi futhi bavame ukuselapha.
Noma ngabe kunjani, into eyodwa isobala: ukwanda kwesifo sikashukela sohlobo 2 kuya ngokuya kukhula, ikakhulukazi kubantu abasha. Ososayensi bakhala i-alamu - lesi sifo sidinga ukwenziwa ngokushesha ngaphansi kokulawulwa futhi sithole izindlela ezisebenzayo zokwelapha. "Indlela yokuphila enempilo ingasiza kulokhu. Isisindo esinempilo sidlala indima ebaluleke kakhulu. Futhi ukukhula kwesifo kumele kuvikeleke kuwo wonke ubudala," kusho uDkt Magliano.
Labo asebevele benesifo sikashukela, odokotela baluleka ukuthi banake kakhulu impilo yenhliziyo ukuze banciphise amathuba okuhlaselwa yinhliziyo nezinye izinkinga. Ukuze wenze lokhu, udinga ukugcina izinga likashukela endaweni eluhlaza, futhi kunamathuba amaningi kulokhu, kufaka phakathi umuthi, lokhu manje kunangaphambili. Kubalulekile futhi ukuqapha amazinga wesisindo nama-cholesterol, ayakhumbuza.
"Singayikhulisa impilo yethu uma sihlasela lesi sifo ngobudlova njengathi," kuphetha uDkt Zonszain, futhi isiluleko sakhe kufanele silandelwe.
