Yintoni iProlactin? Masithethe ngayo ngokulula!

Usenokuba ukhe weva okanye awuzange uve ngegama elithi 'prolactin'. Kodwa le yi-hormone eyenza imisebenzi emininzi ebalulekileyo emizimbeni yethu, ingakumbi emizimbeni yabasetyhini. Ngokuchanekileyo, le hormone ibalulekile kumama ukuvelisa ubisi lomntwana wakhe. Ngoko makhe sijonge ukuba yintoni le prolactin, yintoni eyenzayo emizimbeni yethu, kwaye kwenzeka ntoni ukuba iyanda okanye iyancipha. Masithethe ngayo yonke into ngokulula.

Yintoni eyenziwa yiprolactin emzimbeni wethu?

Ngamafutshane, i-hormone prolactin ibandakanyeka kumakhulu emisebenzi emizimbeni yethu. Kodwa kukho ezimbini eziphambili . Masibone ukuba zeziphi.

• Eyokuqala kukuncedisa ekuphuhliseni amabele avelisa ubisi emabeleni.
• Okwesibini kukuxhasa ukuveliswa kobisi kunye nokuncancisa kunye nokuncancisa emva kokuba umntwana ezelwe.

Ezi zizinto ezimbini eziphambili. Ngaphandle kwezi, lo mhlobo ubizwa ngokuba yiprolactin unceda kwimisebenzi emininzi emincinci.

Indlela yokunceda ukukhula kwamabele kunye nokuncancisa

Ngoku makhe sibone ukuba oku kwenzeka njani. Xa ukhulelwe, i-hormone prolactin, kunye nezinye ii-hormone ezimbini ezibizwa ngokuba yi-estrogen kunye ne -progesterone, zisebenza kunye ukukhulisa izicubu zebele kunye nokulungiselela amabele ukuvelisa ubisi. Ngokukodwa, ezi hormone zisebenza kunye ukuphuhlisa iingxowa ezincinci ngaphakathi kwamabele ezenza ubisi, ezibizwa ngokuba yi-mammary alveoli. Kungaphakathi kwezi ngxowa zobisi apho ubisi luveliswa kwaye lugcinwa khona.

Emva kokuba umntwana ezelwe, inani lee-receptors (ii-receptors) kwezi seli ze-milk follicle ezisabela kwi-hormone ye-prolactin liyanda. Oku kuthetha ukuba i-prolactin inamathuba amaninzi okusebenza. Yiyo loo nto ubisi luqala ukuphuma kwi-nipple (ukuncancisa). Ayisiyondlela imangalisayo le?

Iprolactin ngexesha lokukhulelwa nasemva kokubeleka

I-Prolactin yi-hormone ekhethekileyo kakhulu. Isizathu saloo nto yinkqubo ebizwa ngokuba yi -positive feedback loop . Uyazi ukuba yintoni leyo? Cinga ngale ndlela, xa umntwana encanca ubisi, olo vuselelo luthumela isignali kwi-pituitary gland ukuba 'ivelise i-prolactin engaphezulu'. Emva koko i-pituitary gland ivelisa i-prolactin engaphezulu. Xa i-prolactin isanda, imveliso yobisi nayo iyanda. Okukhona umntwana encanca, kokukhona kuza ubisi oluninzi. Yiloo nto le positive feedback loop ibizwa ngayo. Oko kukuthi, isenzo sonyusa eso senzo nangakumbi. Umntwana oncanca ingono yeyona nto iphambili ekukhulisweni kwe-prolactin engaphezulu.

Iveliswa njani iprolactin? Ivela phi?

Uninzi lweprolactin eveliswa emzimbeni wakho luvela kwi-gland encinci ekwisiseko sobuchopho bakho ebizwa ngokuba yi-pituitary gland. Le gland yiyo eyenza i-prolactin kwaye iyikhuphele emzimbeni wakho.

Kodwa kukwakho nabantu abanokulawula le prolactin.I-neurotransmitter dopamine kunye ne-hormone i-estrogen zimisela ukuba ingakanani i-prolactin ekufuneka yenziwe kunye nexesha lokuyikhupha. Zifana namapolisa etrafikhi, amisa xa kufuneka aze awavumele ukuba ahambe xa kufuneka.

Ziziphi izizathu ezinokubangela utshintsho kumanqanaba eprolactin?

Amanqanaba eprolactin awafani rhoqo. Ngamanye amaxesha ayatshintshatshintsha ngokwendalo.

Kuqhelekile ukuba amanqanaba eprolactin anyuke kancinci.

Kuqhelekile ukuba amanqanaba eprolactin anyuke ngexesha lokukhulelwa nokuncancisa. Nangona kunjalo, kukho amaxesha apho amanqanaba eprolactin anokunyuka kancinci okwethutyana, oko kuthetha ukuba ixesha elifutshane . Ezi ziquka:

• Uxinzelelo lomzimba: Umzekelo, xa uziva iintlungu eziqatha.
• Xa uzilolonga.
• Emva kokutya isidlo.
• Emva kwesondo.
• Ukuvuselelwa kweengono okungenamsebenzi nokuncancisa: Kunokubangelwa ziimpahla ezithile okanye ezinye izizathu.
• Ukuba kukho ukwenzakala kwindawo yesifuba.
• Ukuba kukho imeko efana nokuxhuzula.

Nangona amanqanaba eprolactin esenokunyuka kancinci ngeli xesha, adla ngokubuyela kwisiqhelo emva kwexesha elithile. Akukho nto inokubangela ukukhathazeka ngayo.

Amanqanaba eprolactin aphakanyisiweyo ixesha elide (i-hyperprolactinemia)

Kodwa ngamanye amaxesha, ngenxa yeemeko ezithile zonyango okanye amayeza athile, amanqanaba eprolactin anokuba phezulu ngendlela engaqhelekanga ixesha elide, oko kukuthi, ixesha elide. Le yimeko esiyibiza ngokuba yi-hyperprolactinemia .

Eyona nto ibangela oku yimeko ebizwa ngokuba yi -prolactinoma . Le yithumba elincinci elikhula kwi-pituitary gland, ingakumbi i-pituitary adenoma . Nangona kunjalo, le ayingomhlaza, kodwa yithumba elingenabungozi nelinyangekayo kwiimeko ezininzi.

Ezinye iimpawu ezinokwenzeka xa une-hyperprolactinemia zezi:

• Ukungazali: Oku kuthetha ukungakwazi ukukhulelwa .
• Ukulahlekelwa ngumdla kwisondo.
• Ukuphuma kolwelo olufana nobisi kwiingono nangona ungancancisi (iGalactorrhea).
• Ukuya exesheni okungaqhelekanga kwabasetyhini: Imijikelo yokuya exesheni engenzeki rhoqo.
• Ukungasebenzi kakuhle kwe-erectile kumadoda.

Ukuba uneempawu ezinje, kubaluleke kakhulu ukubona ugqirha, kuba kukho unyango olufanelekileyo lwesi sifo.

Ngaba amanqanaba eprolactin angaphantsi ngokungaqhelekanga?

Ewe, ngamanye amaxesha amanqanaba eprolactin anokuba phantsi ngendlela engaqhelekanga. Kodwa oku kudla ngokuba yingxaki emva kokuba nomntwana. Kuba, ngaphandle kokuba ukhulelwe okanye uncancisa, amanqanaba akho eprolactin ahlala ephantsi. Loo nto yimeko esempilweni.

Ngoko ke, uphawu olulodwa lokuba iprolactin iphantsi kakhulu kukungabikho kokuveliswa kobisi lwebele emva kokuba umntwana ezelwe, okanye ubisi olufumanekayo luphantsi kakhulu.

Kwimeko enjalo, unobangela usenokuba yimeko engaqhelekanga ebizwa ngokuba yi -hypopituitarism , imeko apho i-pituitary gland yakho ingavelisi i-hormone enye okanye ezingaphezulu ngokufanelekileyo.

Kodwa into enye ekufuneka uyikhumbule kukuba ukuncancisa yinkqubo enzima kakhulu. Zininzi izizathu zokuba ubisi lungabi ninzi. Ngoko ke ukuba unengxaki efana nokungabi nabisi olwaneleyo, kungcono ukubona ugqirha okanye umcebisi wokuncancisa.

Ujonga njani amanqanaba eprolactin? Luhlobo luni lovavanyo olwenziwayo?

Ungafumana uvavanyo lwegazi ukuze ufumane ukuba angakanani na amanqanaba akho e-prolactin. Oku kubizwa ngokuba luvavanyo lwe-prolactin (PRL) .

Ukuba uneempawu ezibonisa ukuba unokuba namanqanaba aphezulu e-prolactin, njengoko bekutshiwo ngaphambili (umzekelo, ukuphuma kobisi kwiingono zakho xa ungancancisi, imijikelo yokuya exesheni engacwangciswanga), ugqirha wakho unokucebisa ukuba wenze olu vavanyo lwe-prolactin.

Olu vavanyo lukwanceda ekuboneni indlela esebenza ngayo i-pituitary gland.

Amanqanaba aqhelekileyo eprolactin afanele abe njani?

Makhe sijonge amanye amaxabiso aqhelekileyo kumanqanaba e-prolactin yomntu ophilileyo. Nangona kunjalo, la maxabiso anokwahluka kancinci kwilabhoratri nganye. Ke ngoko, kubalulekile ukujonga uluhlu oluqhelekileyo kwingxelo yakho.

La ngamaxabiso amkelekileyo ngokubanzi:

• Kumadoda: Kufuneka ibe ngaphantsi kwe-20 ng/mL (ii-nanograms nge-milliliter).
• Kwabasetyhini abangakhulelweyo okanye abangancancisi: Kufuneka ibe ngaphantsi kwe-25 ng/mL.
• Kwabasetyhini abakhulelweyo okanye abancancisayo: Uluhlu lunokuba phakathi kwe-80 ng/mL kunye ne-400 ng/mL.
