Ukudlula kwisisu luhlobo lotyando kunyango lokutyeba kakhulu equka ukwenza ingxowa encinci esiswini. Ikwabizwa ngokuba kukuhlinzwa ngokudlula esiswini, yeyona ndlela isetyenziswa kakhulu e-US nakwamanye amazwe, apho ugqirha esahlulahlula isisu sibe yinxalenye enkulu kwaye incinci kakhulu.
Inxalenye encinci ithungiwe okanye ifakwe isitokhwe, yenza ingxowa enokubamba ikomityi enye yokutya. Ngesisu esincinci abantu baziva behluthi ngokukhawuleza kwaye batya kancinci. Esi sicwangciso sibizwa ngokuba "sisithintelo" kuba ubungakanani obutsha besisu buyasithintela isixa sokutya esinokubamba.
Inxalenye yesibini yotyando ineBypass. Ugqirha usikhulula isikhwama esitsha esincinci kwisisu esisininzi kunye nenxalenye yokuqala yamathumbu amancinci (i-duodenum) yokuqhagamshela kwinxalenye yamathumbu amancinci asezantsi (ijejeum). Obu buchule botyando bubizwa ngokuba yi "Roux-Y."
Emva kwe "Kwaye iRoux", Ukufakwa kweekhalori kunye nezondlo kuyacothaKuba ukutya kudlula ngokuthe ngqo ukusuka esiswini ukuya kwijejeum, kuthintela i-duodenum. Ngenxa yale ndlela, le ndlela yokunciphisa umzimba ibizwa ngokuba yi "malabsorptive."
Ngokubanzi, ukutyiwa kwesisu kunye ne- «Roux-Y» kwenziwa ngexesha lotyando olufanayo, xa zenziwe kunye, zibizwa ngokuba yi- «Gastric bypass with the Roux-Y technique». Ihlala iqhutywa ngokwasemzimbeni (ngokusika okuncinci esiswini), nangona kukho iimeko apho kungenakwenzeka khona. Emva koko ogqirha banokwenza i-laparotomy (ukusika okukhulu embindini wesisu)
Ukubuyisela
Emva kotyando ngokudlula esiswini, abantu mabahlale esibhedlele iintsuku ezimbini ukuya kwezintathu ngaphambi kokuba ubuye ekhaya-ngamanye amaxesha kuncinci kwaye abanye ngakumbi, kuxhomekeke kwisigulana-, nangona kuhlala kucetyiswa ukuba ungaphindi ujoyine inkqubo kude kube emva kweeveki ezimbini ukuya kwezintathu.
Iingxaki ezinzima zinqabilengakumbi xa inkqubo yenziwa ngugqirha onamava. Nangona kunjalo, ezinye iingxaki zempilo zinokubakho ngenxa yotyando. Umzekelo, ukungafaki i-iron okanye i-calcium eninzi njengangaphambili kunokubangela i-anemia kunye ne-osteoporosis. Ukuthatha izongezo kunye nokuvavanywa rhoqo kunokunciphisa umngcipheko.
