Ngaphambi kokuyeka ukuya exesheni, abasetyhini banomngcipheko ophantsi wesifo senhliziyo kunamadoda, kodwa oko kuyatshintsha emva kokuba bedlule kwinguqu. Nangona isizathu singaqondwa ngokupheleleyo, entsha kufunda kwiJournal yePhysiology ibonelela ngendlela enye: utshintsho lwehomoni ukunciphisa umthamo yabafazi for yenza imithambo yegazi emincinci kwimisipha yakho, ukwandisa umngcipheko weemeko ze-cardiovascular and especially type 2 diabetes.
Ngethamsanqa, abaphandi bacebisa, oku akufuneki kuphephe, kuba umthambo wexesha elifutshane unokunceda - emva kokuyeka ukuya exesheni, kodwa ngakumbi ngaphambi kwayo.
Abaphandi bajonge amaqela amabini abasetyhini: i-12 yayiphakathi kweminyaka engama-59 kunye ne-70 kwaye abahlanu baphakathi kweminyaka eyi-21 kunye ne-28. Omabini la maqela enze i-biopsy yezihlunu zethanga phambi kokuba aqale, emva koko aqeqeshwa kwisithuba seeveki ezisibhozo esebenzisa iibhayisekile ezijikelezayo ezimodareyithayo ukuya phezulu.
Iqela elincinane elaqalisa ukwenza umthambo ngaphambi kokuba lifikelele ekuyekeni ukuya exesheni liye labonisa ukwanda kwenani leemithambo-luvo, okanye imithambo emincinane yegazi, kwizicubu zezihlunu zamathambo ekupheleni kwexesha lofundo, ngoxa iqela elikhulileyo lingazange. Ii-capillaries, ezinceda iswekile kunye namafutha ukuba afakwe kwizihlunu ukuze zisetyenziswe ngokufanelekileyo njengamafutha, nazo zinefuthe ekuxhathiseni i-insulin. Yiyo loo nto ukuba namandla amancinci okuphuhlisa ezintsha kunokukhokelela kwiingxaki zentliziyo.
Iinzuzo zokuzilolonga emva kokuyeka ukuya exesheni
Nangona kunjalo, oko akuthethi ukuba umthambo we-postmenopausal awuqatshelwa. Kwisifundo, nangona abazange babonise ukukhula kweenwele ezibalulekileyo, iqela elidala kuphuculwe amandla akho okwenza umthambo nge-15 ekhulwini. Oko, kukodwa, kukukhuthaza kwentliziyo.
Ikhonkco phakathi kokulahleka kwe-estrogen, eyenzeka ngexesha lokuyeka ukuya exesheni, kunye notshintsho olubi kwimithambo yegazi lusekwe kakuhle. Uphononongo lwangaphambili lucebise ukuba ezinye zeempawu eziphambili zokuyeka ukuya exesheni, njenge ukuvutha okutsha kunye ukuphazamiseka kokulala, inokunxulumana nale nkqubo yokuguga kwemithambo.
Imida ephambili yophononongo lwangoku lubukhulu besampulu encinci kunye nexesha elifutshane. Nangona kunjalo, sisiqalo esithembisayo esinokukhokelela kuphononongo olukhulu oluvavanya iimpembelelo zexesha elide ezinokubakho zokutshintsha komthambo wegazi ngexesha lokuyeka ukuya exesheni okanye kwinguqu yokuyeka ukuya exesheni.
Okwangoku, kunzima ukudlula kwisigqibo sokuba neenyanga ezimbalwa zoqeqesho oluqhelekileyo lunokuba nefuthe elibi kwimpilo yentliziyo, ngoku nakwixesha elizayo.
