Ukuba ungumama okhulelweyo, umama oncancisayo, okanye umntu olindele umntwana, mhlawumbi ukhe weva igama elithi "prolactin". Le yi-hormone ebaluleke kakhulu emzimbeni wethu, ingakumbi kubasetyhini, ebandakanyeka kwizinto ezininzi, ezinje ngokuzala kunye nokuveliswa kobisi lwebele. Ngoko ke masithethe ngayo ngokulula nangendlela ehloniphekileyo namhlanje.
Ngamafutshane, yintoni iprolactin?
Cinga ngemizimba yethu njengomzi-mveliso omkhulu oneengcali zomsebenzi ngamnye. Iihomoni zizithumeli ezithwala imiyalezo yokugcina lo mzi-mveliso usebenza kakuhle. I-Prolactin , ekwaziwa ngokuba yiLactotropin okanye i-PRL, yenye yezithumeli zibalulekileyo.
Nangona le hormone ibandakanyeka kumakhulu emisebenzi emzimbeni wethu, inemisebenzi emibini ephambili:
1. Ukuncedisa ekuvelisweni kobisi lwebele (Ukuncancisa): Isizathu esiphambili sokuba umama akwazi ukuvelisa ubisi lomntwana wakhe yi-hormone prolactin.
2. Inegalelo ekuphuhlisweni kwamabele: Le hormone inoxanduva lokuphuhlisa amadlala avelisa ubisi emabeleni, ingakumbi ngexesha lokukhulelwa, kwaye iwalungiselele ukuncancisa.
Ngamafutshane, yile hormone yeprolactin eyalela imizimba yethu ukuba ivelise isipho esixabisekileyo esibizwa ngokuba "lubisi lwebele" esifunekayo ukuze kwaneliswe indlala yomntwana emva kokuba nomntwana.
Ivela phi le hormone iProlactin? Isebenza njani?
Ngaphantsi kwengqondo yethu, kukho idlala elincinci kodwa elinamandla kakhulu elinobukhulu obufana ne-pea encinci ebizwa ngokuba yi-Pituitary Gland . Lifana "negumbi lokulawula" lenkqubo yehomoni yomzimba wethu. Kukule gumbi lokulawula apho i-prolactin iveliswa khona ngobuninzi kwaye ikhutshwe egazini.
Kodwa oku akwenzeki nje kuphela. Kukho iinkosi ezimbini ezilawula i-pituitary gland, ziyixelela ukuba zenze i-prolactin kwaye ziyixelela ukuba iyeke ukuyenza.
- I-Dopamine: Le yi-neurotransmitter engqondweni yethu. I-Dopamine isebenza ngokunciphisa imveliso ye-prolactin. Oko kukuthi, i-dopamine ithintela i-prolactin ukuba ingandi kakhulu.
- I-estrogen: Le yi-hormone ebalulekileyo yabasetyhini. I-estrogen inceda ekwandiseni imveliso ye-prolactin.
Njengoko amanqanaba e-estrogen esanda ngexesha lokukhulelwa, nemveliso ye-prolactin iyanda. Oku kubangela ukuba amadlala avelisa ubisi (i-mammary alveoli) emabeleni akhule aze alungiselele ukuvelisa ubisi lomntwana.
Okumangalisayo kukuba emva kokuba umntwana ezelwe, xa umntwana encanca ibele likanina, loo myalezo uya ngqo engqondweni uze uxelele i-pituitary gland ukuba "yenze i-prolactin engaphezulu." Njengoko i-prolactin isanda, ubisi oluninzi luyaveliswa. Oku sikubiza ngokuba yi-positive feedback loop.Oko kukuthi, xa inkqubo iqala, ivuselela loo nkqubo nangakumbi.
Kutheni amanqanaba eprolactin etshintsha ngesiquphe?
Amanqanaba eprolactin awafani rhoqo. Ngamanye amaxesha ayanda ngokwendalo, kwaye ngamanye amaxesha ayanda ngenxa yesifo.
Iimeko apho amanqanaba eProlactin enyuka ngokwendalo
Ezi zinto zinokubangela ukuba amanqanaba akho e-prolactin anyuke okwethutyana, oko kuthetha ukuba okwexeshana elifutshane. Oku kuqhelekile kwaye akukho nto inokubangela ukuba ukhathazeke ngayo.
- Uxinzelelo lomzimba: Xa uziva intlungu enzulu.
- Ukuzilolonga: Emva kokuzilolonga kakuhle.
- Ukutya: Emva kokutya.
- Isondo: Emva kwesenzo sesondo.
- Ukuvuselelwa kwamabele: Ukuba amabele avuselelwa ngaphandle kokuncancisa.
- Ukulimala esifubeni: Ukuba kukho ingozi okanye ukwenzakala kwindawo yesifuba.
- Ukukhulelwa nokuncancisa: Amanqanaba eprolactin ngokwendalo aphezulu kakhulu ngeli xesha.
Amanqanaba aphezulu eprolactin (i-Hyperprolactinemia)
Ezinye iimeko zonyango okanye amayeza zinokubangela ukuba amanqanaba e-prolactin ahlale ephezulu ngendlela engaqhelekanga ixesha elide. Le meko yaziwa ngokwezonyango njenge- hyperprolactinemia .
Eyona nto ibangela oku yimeko ebizwa ngokuba yi -prolactinoma . Le yithumba elincinci, elingenalo umhlaza (ngesiqhelo) elikhula kwi-pituitary gland. Le thumba ikhupha i-hormone prolactin ngokungeyomfuneko.
Xa amanqanaba eprolactin enyuka ngendlela engaqhelekanga, ezi mpawu zilandelayo zinokwenzeka.
| Uphawu | Ngubani ochaphazelekayo kunye nengcaciso elula |
|---|---|
| Ukungazali | Ingachaphazela abafazi kunye namadoda. Xa amanqanaba eprolactin enyuka, iphazamisana nokukhutshwa kweqanda kunye nokuveliswa kwesidoda. |
| Umjikelo wenyanga ongaqhelekanga wokuya exesheni | Iyachaphazela abafazi. Ukuya exesheni kusenokungahambelani, kuphele ixesha, okanye kuphele ngokupheleleyo. |
| Ukuphuma kobisi oluvela emabeleni (iGalactorrhea) | Le meko inokwenzeka kumfazi okanye kwindoda engakhulelwanga okanye engancancisi. |
| Ukuncipha komnqweno wesondo | Iqhelekile kubafazi nakumadoda. |
| Ukungasebenzi kakuhle kwe-erectile | Ichaphazela isini samadoda. |
Ngaba amanqanaba eprolactin angaphantsi ngokungaqhelekanga?
Ewe, inokwenzeka. Kodwa ayiqhelekanga kakhulu. Ngokwesiqhelo, ngaphandle kokuba ukhulelwe okanye uncancisa, amanqanaba akho e-prolactin aphantsi. Loo nto ikwimeko entle.
Ngoko ke, uphawu olulodwa lokuba amanqanaba eprolactin aphantsi ngendlela engaqhelekanga kukungabikho kokuveliswa kobisi lwebele emva kokuzala umntwana .
Kwimeko enjalo, unobangela usenokuba yimeko ebizwa ngokuba yi -hypopituitarism . Oku kuthetha ukuba i-pituitary gland ayivelisi i-hormone enye okanye ezingaphezulu ezifunekayo. Le yimeko engaqhelekanga kakhulu.
Kodwa kufuneka ukhumbule oku. Amanqanaba aphantsi e-prolactin ayisosizathu sodwa sokuba umama abe nobisi oluncinci. Kunokubakho ezinye izinto ezininzi ezibangela oku. Ke ngoko, ukuba uneengxaki zokuncancisa, kungcono ukubona ingcali okanye umcebisi wokuncancisa malunga noko.
Ulinganisa njani amanqanaba akho eProlactin?
Oku kulula kakhulu. Ugqirha wakho angayalela uvavanyo lwegazi (uvavanyo lwe-PRL) ukujonga inqanaba le-prolactin egazini lakho. Oku kufana novavanyo lwegazi oluqhelekileyo. Ukuba uneempawu ezichazwe apha ngasentla kwaye ukrokrela ukuba i-pituitary gland yakho isebenza kakuhle, ugqirha wakho uya kuyalela olu vavanyo.
Zithini iinqanaba zeprolactin eziqhelekileyo?
Itheyibhile engezantsi ibonisa uluhlu oluqhelekileyo lwamanqanaba e-prolactin kumntu ophilileyo. Nangona kunjalo, la maxabiso anokwahluka kancinci kwilabhoratri nganye. Ke ngoko, kubalulekile ukujonga icandelo elithi "Uluhlu Oluqhelekileyo" kwingxelo yakho.
| Udidi | Ixabiso eliqhelekileyo (ng/mL) |
|---|---|
| Amadoda | Ngaphantsi kwe-20 ng/mL |
| Abafazi abangakhulelwanga nabangencancisi | Ngaphantsi kwe-25 ng/mL |
| Abafazi abakhulelweyo okanye abancancisayo | Phakathi kwama-80 kunye nama-400 ng/mL |
Ukuba unenkxalabo malunga neziphumo zakho, ungathandabuzi ukuthetha nogqirha wakho ngayo.
Ufanele uye nini kugqirha malunga neprolactin?
Ukuba ucinga ukuba uneempawu eziphezulu ze-prolactin esizixubushe apha ngasentla (ezifana nokuya exesheni okungacwangciswanga, ukungazali, kunye nokukhupha ubisi emabeleni akho), bona ugqirha wakho ngoko nangoko . Unokwenza uvavanyo, afumane unobangela, aze akunike unyango ukuba kuyimfuneko.
Ukuba ungumama oncancisayo kwaye unengxaki yokungabi nabisi olwaneleyo, funa iingcebiso zonyango malunga naloo nto.
I-Prolactin yi-hormone ebalulekileyo ekukhulelweni nasekuncanciseni. Kodwa ngaphandle koko, asicingi kakhulu ngayo de kuvele iimpawu ezingaqhelekanga. Ngoko ke lumka ngotshintsho emzimbeni wakho. Ukuba uneengxaki, funa ingcebiso kugqirha.
Umyalezo Wokuya Ekhaya
