Ngaba ulindele umntwana? Okanye sele ukhulelwe kwaye ulinde ukuba umntwana wakho omtsha afike? Ugqirha wakho usenokuba ukuxelele la mazwi athi ' Uvavanyo lweMfuzo '. Ukuva eli gama, usenokuba uzive usoyika kancinci, unomdla, kwaye udidekile kancinci. "Owu Thixo wam, yintoni le vavanyo? Ngaba kufuneka ndenze oku? Ngaba umntwana wam uza kuba semngciphekweni?" Kuqhelekile ukuba kuvele imibuzo emininzi engqondweni. Ngoko ungoyiki. Namhlanje, siza kuthetha ngale nto ngokulula, ngendlela onokuyiqonda.
Olu vavanyo lwemfuza lubaluleke kubani?
Ngamafutshane, nawuphi na umfazi unethuba lokwenza olu vavanyo ngexesha lokukhulelwa okanye ngaphambi kokukhulelwa. Ngamanye amaxesha utata womntwana naye uthunyelwa kolu vavanyo. Siza kuxoxa ngesizathu soku kamva.
Ngokwesiqhelo, ugqirha wakho ngokuqinisekileyo uya kuthetha ngolu vavanyo kwiimeko ezilandelayo:
- Imbali yosapho: Ukuba umntu kusapho lwakho, okanye kusapho lukatata womntwana, unesifo semfuza (umzekelo, i-thalassemia, i-sickle cell anemia), olu vavanyo lunokunceda ekuqinisekiseni ukuba umntwana wakho angasifumana na eso sifo semfuza.
- Ubudala: Ngokubanzi, ukuba umama uneminyaka engaphezu kwama-35 ubudala, umngcipheko wezifo ezithile zemfuza (ingakumbi i-Down syndrome) uyanda kancinci. Ke ngoko, oogqirha bacebisa olu vavanyo kwiimeko ezinjalo.
- Imvelaphi yoBuzwe: Kukho izifo ezithile zemfuza ezichaphazela amaqela ahlukeneyo eentlanga ehlabathini. Umzekelo, abantu baseMpuma Yurophu okanye imvelaphi yobuYuda baseAshkenazi basengozini enkulu yezifo ezibizwa ngokuba yiTay-Sachs kunye neCanavan . Abantu baseAfrika basengozini enkulu yesifo se-sickle cell. Abantu abamhlophe basengozini enkulu ye- cystic fibrosis . Nangona le yimizekelo evela kwihlabathi liphela, kubalulekile ukuthetha nogqirha wakho malunga nemvelaphi yosapho lwakho.
Zenza ntoni kanye kanye ezi mvavanyo?
Oogqirha basebenzisa iintlobo ezahlukeneyo zovavanyo lwemfuza . Ezi zinokwahlulwa zibe ziindidi ezimbini eziphambili. Masijonge ngale ndlela ukuze sikuqonde ngokucacileyo.
| Uhlobo lovavanyo | Kalula nje, kwenzeka ntoni ngale nto? |
|---|---|
| Uvavanyo loHlolo | Ezi mvavanyo zisetyenziselwa ukufumanisa umngcipheko wokuba umntwana wakho abe neziphene ezithile zokuzalwa. Imizekelo ibandakanya iDown syndrome, iTrisomy 18, kunye neTrisomy 13. Oku kufana nokuqikelela amathuba okuba kwenzeke ingozi yendlela. |
| Uvavanyo lwabathwali | Oku kuvavanya ukuba wena, okanye utata womntwana, ningabathwali besifo sofuzo. 'Isithwali' sithetha ukuba umntu akanazo iimpawu, kodwa isithwali sesifo sisemzimbeni wakhe. Eso sithwali semfuza sinokudluliselwa emntwaneni. Imizekelo: I-Cystic fibrosis, i-Fragile X syndrome, isifo seSickle cell. |
Ngubani umthwali?
Masicacise oku kancinci. Khawucinge ukuba udinga ii-genes ezimbini ukuze ufumane isifo esithile. Esinye sivela kumama wakho kwaye esinye sivela kutata wakho. Umthwali uthetha ukuba umntu une-genes enye kuphela ebangela isifo. Ke ngoko, abaphuhlisi sifo kwaye ababonisi zimpawu. Nangona kunjalo, ukuba bobabini abazali bangabathwali, umntwana uza kufumana i-gene ebangela isifo kubazali bobabini, kwaye kukho ithuba lokuba umntwana uza kufumana isifo. Yiyo loo nto uvavanyo lomthwali lubalulekile.
Olu vavanyo lwenziwa njani? Ngaba kukho into omele uyoyike?
Kulapho uninzi lwabantu luyoyika khona. Kodwa kulula kakhulu. Ngokwesiqhelo umongikazi uza kuthatha isampuli yegazi engalweni yakho, okanye kwezinye iimvavanyo , athathe isampuli yamathe . Yiyo leyo.
Oku akuyi kubangela monakalo okanye ingozi kuwe okanye kusana lwakho olungekazalwa. Oku kufana nje nokuhlolwa igazi rhoqo. Ngoko ke musa ukoyika ngokungeyomfuneko.
Zithini iziphumo?
Le yeyona nto ibalulekileyo ekufuneka wonke umntu ayiqonde.
Uvavanyo lokuhlolwa kwemfuza aluqinisekisi ukuba umntwana wakho uza kuba nesifo. Lubonisa kuphela 'umngcipheko' wokuba nesifo.Kuxhomekeke nje ekubeni iphezulu okanye iphantsi na. Oko kuthetha ukuba ukuba iziphumo zakho zibuya 'zinomngcipheko ophezulu', akuthethi ukuba umntwana wakho ngokuqinisekileyo unesifo. Kuthetha nje ukuba kufuneka ujonge ngakumbi.
Ukuba ufumana iziphumo 'ezinobungozi obukhulu', ugqirha wakho unokucebisa ezinye iimvavanyo zokuxilonga. Umzekelo:
- I-Amniocentesis: Kule meko, inani elincinci kakhulu lolwelo lwe-amniotic olujikeleze umntwana lithathwa ngesirinji kwaye lihlolwe kusetyenziswa i-ultrasound scan.
- I-Chorionic Villus Sampling (CVS): Kule meko, kuthathwa iqhekeza elincinci kakhulu lesicwili kwi-placenta lize lihlolwe.
Olu vavanyo luyinkimbinkimbi ngakumbi kunovavanyo lwegazi olukhankanyiweyo ngaphambili. Lunokuba nomngcipheko omncinci kakhulu. Ngoko ke olu vavanyo lwenziwa kuphela ukuze kufunyaniswe ukuba yintoni kanye kanye 'ingozi ephezulu'. Ugqirha wakho uza kukuchazela konke oku ngokupheleleyo.
Kutheni kubalulekile ukuba notata wakho ahlolwe?
Njengoko besitshilo ngaphambili, ukuze ezinye izifo zivele, umntwana kufuneka afumane i-gene evela kumama nakutata. Khawuthelekelele ukuba ungumthwali we-cystic fibrosis. Usenokuba nexhala. Kodwa ukuba utata womntwana uvavanyiwe kwaye akangomthwali (ongenayo), amathuba omntwana okufumana esi sifo aphela ngokupheleleyo. Yiyo loo nto ngamanye amaxesha kubaluleke kakhulu ukuvavanya abazali bobabini.
Luvavanyo olu luqhutywa kangaphi ngexesha lokukhulelwa?
Ngokwesiqhelo, kwenziwa kube kanye. Olu vavanyo lwenziwa kwiiveki ezithile ngexesha lokukhulelwa.
Umyalezo Wokuya Ekhaya
- Uvavanyo lwemfuza yindlela yokufumanisa umngcipheko womntwana wakho wokuba nesifo semfuza, kodwa aluqinisekisi ukuba esi sifo sikhona.
- Uninzi lwezi zinto zenziwa ngesampulu yegazi okanye isampuli yamathe, ngoko ke akukho mngcipheko kuwe okanye kumntwana wakho.
- Musa ukoyika ukuba iziphumo zovavanyo zithi 'umngcipheko ophezulu'. Oko akuthethi ukuba unesifo, kodwa kuthetha ukuba kufuneka uphande ngakumbi ngaso.
- Xoxa ngayo nayiphi na imibuzo, iinkxalabo, okanye amathandabuzo onawo malunga nezi mvavanyo, iziphumo zazo, kunye namanyathelo alandelayo omele uwathathe nogqirha wakho . Uza kukuchazela yonke into.
