Luhlobo luni lokuhlolwa kwegazi olukhona futhi kungani lwakhiwe?
Ukuhlaziywa okujwayelekile kwegazi, okwenziwe ngesikhathi sokukhulelwa, kukuvumela ukuba uhlole isimo somzimba wesifazane, ukudalula izinqubo zokuvuvukala ezifihlekile. Ucwaningo luveza ngokuqondile ukusabela komzimba womuntu ekushintsheni okwenzeka kuyo, kufaka phakathi izifo. Ukubheka okuphawulekayo ekuhlaziyweni kwemiphumela kunikezwa kuleso sibonakaliso njengezinga le-hemoglobin, ukwehla kwalo okungabonisa ukuthi i- anemia, eqinisweni, ebangela i-hypoxia ye-fetus.
Ukuze unqume ukukhulelwa ngokwayo ngendlela yokuhlolwa kwegazi, ngosuku lwesihlanu isifundo senziwa, esibizwa ngokuthi ukuzimisela kwezinga le-hCG. I-Countdown ivela ngosuku lokusola okusolwayo. Ngokushesha, le hormone iqala ukuhlanganiswa ngemuva kokukhulelwa futhi ikhombise ukufakwa kwesitshalo.
Ukuhlaziywa kwegazi ngegazi, okushiwo ngesikhathi sokukhulelwa, kuhloswe ukukhomba ezinyathelweni zakuqala zokuthuthukiswa kwengane ye-anomalies engavamile ehambisana nokuguqulwa kwamagciwane. Phakathi kwazo yi-syndrome ye-Edwards, i-Down, ukwephula, okufana ne-trisomy, polysomy. Uma zisungulwa, ukukhishwa kwesisu kuxazululwe.
Ukuvivinya igazi kwegazi, okubekiwe kwabesifazane ngesikhathi sokubeletha, kunikeza ithuba lokuhlola izici zamaprotheni, i-lipid metabolism, ukuhlunga kwamanoni egazini, izinga lamavithamini kanye nezinsizakalo eziwusizo. Ukuqapha okukhethekile kubhalwa amaprotheni okuhlushwa, imingcele ye-nitrogen metabolism. Ukuhlolwa kwezinto eziphilayo kuhlanganisa nokuhlolwa kwegazi nge-glucose, okuvame ukwenziwa ngesikhathi sokukhulelwa. Nguye ovumela ukukhomba ukwephulwa okunjalo njengesifo sikashukela. Ngenxa yokuzwela komzimba wesifazane okhulelwe ukuba i-insulin ebangelwa isenzo se-prolactin ne-estrogens, izinguquko zokubekezelelana kwe-glucose, okuholela ekuthuthukiseni isifo sikashukela sokubeletha.
