Yintoni eyenza umfazi okhulelweyo aphathwe sisicaphucaphu?

Yintoni eyenza umfazi okhulelweyo aphathwe sisicaphucaphu?

Uphononongo lwakutsha nje lubonise ukuba ihomoni ekhuselwe yimveku engekazalwa ngunobangela wesicaphucaphu kunye nokugabha abathi abafazi abaninzi babandezeleke ngexesha lokukhulelwa, into ebalulekileyo efunyenweyo enokuthi ivule indlela yonyango kwezi meko.

Ukuya kuthi ga kwisixhenxe kwabasetyhini abakhulelweyo abalishumi baba nesicaphucaphu kunye nokugabha. Kwabanye abasetyhini (ukukhulelwa omnye ukuya kwabathathu kwi-100 ngalinye), ezi mpawu zinokuba nzima kakhulu, kwaye zibizwa ngokuba yi-vomiting gravidarum, esona sizathu siqhelekileyo sokulaliswa esibhedlele kwabasetyhini kwiinyanga ezintathu zokuqala zokukhulelwa.

Ukuba ebesazi isizathu

UKate Middleton, umfazi weNkosana uWilliam, wabandezeleka kwezi ngxaki ngexesha lokukhulelwa kwakhe kathathu, kwaye ngokutsho kweziphumo zophando olupapashwe kutshanje liphephancwadi elithi "Nature" apho izazinzulu ezivela kwiYunivesithi yaseCambridge kunye nabaphandi baseScotland, eUnited States kunye I-Sri Lanka ithathe inxaxheba, ezi ngxaki zempilo, nokuba zinzima okanye azikho, zibuyela kwi-hormone ekhutshwe yi-fetus, eyiprotheni eyaziwa njenge "GDF-15".

Ukufezekisa esi siphumo, abaphandi bafunda idatha kubasetyhini abafakwe kwinani lezifundo, kwaye basebenzisa uluhlu lweendlela ezibandakanya imilinganiselo yamahomoni egazini labasetyhini abakhulelweyo, izifundo kwiiseli kunye neempuku, njalo njalo.

Abaphandi babonise ukuba iqondo le-nausea kunye nokugabha ukuba ibhinqa libandezeleka ngexesha lokukhulelwa lihambelana ngokuthe ngqo nomthamo we-hormone ye-GDF15 eveliswa yi-fetal part of placenta kwaye ithunyelwe kwi-bloodstream, kunye novakalelo kwisiphumo soku. ihomoni.

Iqela lafumanisa ukuba abanye abafazi banomngcipheko ophezulu kakhulu wemfuza wokuphuhlisa i-hyperemesis gravidarum, ehambelana namanqanaba aphantsi e-hormone egazini kunye nezicubu ngaphandle kokukhulelwa.

Kwangokunjalo, abasetyhini abanengxaki yegazi elifuza eyaziwa ngokuba yi-beta thalassemia, ebavumela ukuba babe namazinga aphezulu kakhulu e-GDF15 ngokwemvelo phambi kokukhulelwa, babe buthathaka ngezinga lesicaphucaphu okanye ukugabha okanye kungabikho nanye kwezi mpawu kwaphela.

Unjingalwazi uStephen O'Reilly, ongumalathisi weWellcome Medical Research Institute for Metabolic Sciences kwiYunivesithi yaseCambridge, nokwangumbhali oncedisana nolu hlolisiso, wathi: “Usana olukhula esibelekweni luvelisa incindi yedlala kumanqanaba umama awathi akuwo. ayiqhelanga. Okukhona esiba novelwano ngale ncindi yedlala, kokukhona eza kuba neengxaki zempilo ezingakumbi.”

“Ukwazi oku kusinika umbono wendlela yokuthintela oku kungenzeki,” wongeze watsho.

Umphandi-mphandi osebenza naye uMarlena Viso osuka kwiDyunivesithi yaseMazantsi eCalifornia, oqela lakhe lachonga ngaphambili ubudlelwane bemfuzo phakathi kwe-GDF15 kunye ne-hyperemesis gravidarum, wahlaselwa yile meko ngokwakhe. Uthi: “Xa ndandikhulelwe, ndandingakwazi nokushukuma ngaphandle kokuba ndibe nesicaphucaphu. “Ndiyathemba ukuba ngoku siyasiqonda isizathu, sizakusondelela ekuphuhliseni unyango olusebenzayo,” wongeze watsho.
