Wake wazibuza ukuthi ubani olawula izinto eziningi kangaka emzimbeni wakho, njengokukhula kwakho, isisindo, ukucindezeleka, kanye nekhono lokuba nabantwana? Ngemuva kwakho konke lokhu kukhona isidalwa esincane kodwa esinamandla kakhulu. Leso yi-gland ebizwa ngokuthi i-Anterior Pituitary, etholakala phansi kobuchopho bethu. Namuhla, sizoxoxa ngalo mphathi omncane.
Kalula nje, iyini i-Anterior Pituitary?
I-Anterior Pituitary ibhekisela engxenyeni engaphambili ye-pituitary gland yakho. Ibizwa nangokuthi "i-Adenohypophysis" kwisayensi yezokwelapha. Le gland ye-pituitary incane kakhulu, njenge-pea. Kodwa umsebenzi wayo mkhulu kakhulu. Itholakala phansi kobuchopho bakho, ngaphansi kwe-"Hypothalamus".
Ake sithi imizimba yethu ifana neqembu elikhulu le-orchestra. Khona-ke le ndlala ye-Anterior Pituitary ingumqhubi walelo qembu le-orchestra. Yiyo eyabela umsebenzi kwezinye izindlala eziningi emzimbeni futhi iqinisekise ukuthi ziwenza kahle. Ngamanye amazwi, yenza umsebenzi omuhle kakhulu wokugcina ibhalansi yesistimu yama-hormone emzimbeni wethu.
I-pituitary gland inezingxenye ezimbili eziyinhloko:
1. I-Anterior Lobe: Lena yi-Anterior Pituitary esikhuluma ngayo namuhla.
2. I-Posterior Lobe: Lokhu kwenza eminye imisebenzi embalwa.
I-Anterior Pituitary ikhiqiza futhi ikhiphe ama-hormone ayisithupha (6) abalulekile emzimbeni wethu egazini. La ma-hormone alawula izinto eziningi emzimbeni wethu.
- Ukukhula
- Ukuguqulwa kwe-Metabolism
- Ukukhiqiza kabusha
- Impendulo yokucindezeleka
- Ukukhiqizwa kobisi lwebele (ukuncelisa)
Yimaphi ama-hormone akhiqizwa yi-Anterior Pituitary gland?
Kulungile, manje ake sibheke ama-hormone ayisi-6 abaluleke kakhulu akhishwa yilo mphathi omncane emizimbeni yethu, nokuthi kwenzekani kuwo. Ukuze lokhu kube lula ukukukhumbula, ake sibheke ithebula.
| I-hormone | Okufanele ukwenze nje |
|---|---|
| I-Adrenocorticotropic Hormone (ACTH) | Kuvuselela izindlala ze-adrenal, ezitholakala ngaphezu kwezinso zethu, ukuze zikhiqize i-hormone i- cortisol , esisiza ukubhekana nokucindezeleka. |
| I-hormone evuselela i-follicle (i-FSH) | Ivuselela ama-ovari kwabesifazane ukuze ibasize bakhule futhi ikhiqize i-hormone i-estrogen . Ivuselela ama-testicles kwabesilisa ukuze ibasize bakhiqize isidoda. |
| I-Luteinizing Hormone (LH) | Kusiza ama-ovary abesifazane ukuthi akhiqize i-hormone i-progesterone . Kusiza amadoda ukuthi akhiqize i-hormone i-testosterone . |
| I-Hormone Yokukhula Komuntu (HGH) | Kubalulekile ekukhuleni ngokomzimba kwezingane. Kusiza ekugcineni imisipha namathambo enempilo kubantu abadala futhi kulawula ukusatshalaliswa kwamafutha emzimbeni. |
| I-Prolactin | Kuvuselela ukukhiqizwa kobisi lwebele ngemva kokubeletha. Kuphinde kuthinte umjikelezo wokuya esikhathini, ukuzala, kanye nokusebenza kocansi. |
| I-hormone evuselela i-thyroid (TSH) | Ivuselela indlala yegilo entanyeni, okubangela ukuthi ikhiqize ama-hormone egilo. Lawa ma-hormone abalulekile ekulawuleni izinga lokugaya ukudla emzimbeni wethu. |
Yiziphi izifo ezihambisana ne-Anterior Pituitary Gland?
Ngenxa yokuthi le ndlala ilawula ama-hormone amaningi kangaka, ngisho nenkinga encane kakhulu ngayo ingabangela izinkinga eziningi zempilo. Lezi zinkinga ngokuvamile zingahlukaniswa zibe izinhlobo ezimbili eziyinhloko.
1. I-Hypopituitarism: Lokhu kusho ukuthi indlala ye-pituitary ayisebenzi kahle, okusho ukuthi ayikhiqizi ama-hormone anele adingekayo.
2. I-Hyperpituitarism: Lokhu kusho ukuthi indlala ye-pituitary isebenza ngokweqile, ikhiqiza ama-hormone amaningi kunokudingekile.
Kunezizathu eziningana eziyinhloko ezenza lezi zimo zenzeke:
- Amathumba akhula endlaleni ye-pituitary - lawa abizwa ngokuthi "ama-adenoma e-pituitary".
- Ukulimala kwe-Anterior Pituitary, Hypothalamus, noma imigudu exhumanisa nabo ngenxa yokulimala, ukutheleleka, noma ukopha (`(pituitary apoplexy)`).
- Ezinye izimo zofuzo, isibonelo 'i-multiple endocrine neoplasia (MEN)'.
Izifo ezibangelwa amazinga aphansi ama-hormone (i-Hypopituitarism)
Lezi zimo zingabangelwa ukwehla kwehomoni elilodwa noma ngaphezulu akhiqizwa yi-pituitary gland.
| Isimo sezokwelapha | Incazelo elula |
|---|---|
| Ukungasebenzi kahle kwe-adrenal yesibili | Ukusebenza kwezindlala ze-adrenal kwehla ngenxa yokwehla kokukhiqizwa kwe-hormone ye-ACTH. |
| Ukuntuleka kwe-hormone yokukhula (GHD) | I-Growth hormone (HGH) ayikhiqizwa ngobuningi obanele. Lesi ngesinye sezizathu ezenza izingane zikhule zibe zimfushane. |
| I-hypogonadism ephakathi | Ukwehla kwama-hormone e-FSH kanye ne-LH kubangela ukwehla kokukhiqizwa kwama-hormone ocansi avela kuma-ovari noma emasendeni. |
| I-hypothyroidism ephakathi | Ukwehla kwe-hormone ye-TSH kubangela ukwehla komsebenzi we-thyroid. |
Izifo ezibangelwa amazinga aphezulu ama-hormone (i-Hyperpituitarism)
Lezi zimo zibangelwa ukukhiqizwa ngokweqile kwehomoni elilodwa noma ngaphezulu le-pituitary.
| Isimo sezokwelapha | Incazelo elula |
|---|---|
| I-Acromegaly | Ukukhiqizwa ngokweqile kwe-hormone yokukhula kwabantu abadala (i-HGH), okubangela ukukhula okungavamile kwamathambo nezicubu (isib., ukwandiswa kwezandla, izinyawo, nobuso). |
| UbuGigantism | Ukukhiqizwa ngokweqile kwe-hormone yokukhula ngesikhathi sobuntwana noma sobusha, okuholela ekukhuleni okungavamile. |
| Isifo sikaCushing | Ukukhiqizwa ngokweqile kwe-hormone i-ACTH kubangela ukuthi umzimba ukhiqize amazinga aphezulu e-cortisol. Lolu uhlobo lwesimo esibizwa ngokuthi 'i-Cushing's syndrome.' |
| I-Hyperprolactinemia | I-hormone i-prolactin ikhiqizwa ngokweqile. |
| I-hyperthyroidism ephakathi | Indlala yegilo iyasebenza ngokweqile ngenxa yokukhiqizwa ngokweqile kwehomoni i-TSH (lesi yisimo esingavamile kakhulu). |
Into ebalulekile ukuthi lezi zimpawu zivame ukufana nezezinye izifo. Ngakho-ke uma usola ukuthi unenkinga efana nale, bona udokotela wakho ngokushesha ukuze akunike iseluleko.
Udokotela uyihlola kanjani impilo yale ndlala?
Uma unezimpawu zenkinga yendlala ye-pituitary, udokotela wakho uzoqala ahlole amazinga akho ama-hormone. Lokhu kuvame ukwenziwa ngokuhlolwa kwegazi .
Uma kukhona ukukhubazeka kuleyo mibiko yokuhlolwa, udokotela wakho angase ancome okuthile okufana ne-MRI scan ukuze ahlole i-pituitary gland ngokuseduze.
Ngingayigcina kanjani i-Anterior Pituitary gland yami iphilile?
Eqinisweni, izinkinga ngale ndlala azikwazi ukuvinjelwa ngaso sonke isikhathi. Kodwa kukhona into eyodwa ebalulekile esingayenza. Lokho ukuvikela amakhanda ethu.
Ukulimala ekhanda kanye nokulimala kobuchopho okubuhlungu (ii-TBI) kungalimaza indlala ye-pituitary, okungaholela ekunciphiseni noma ekwandeni kokukhiqizwa kwama-hormone.
Ngakho-ke, nazi ezinye izinto ongazenza ukuze uvikele ikhanda lakho:
- Gqoka ibhande lesihlalo noma nini lapho usemotweni.
- Shayela ngokuphepha.
- Gqoka isigqoko sokuzivikela uma ugibela ibhayisikili, isithuthuthu, noma udlala imidlalo (ikakhulukazi imidlalo engase ihilele ukushayisana).
- Thatha izinyathelo zokuvimbela ukuwa. Lokhu kubaluleke kakhulu kubantu asebekhulile. Susa izindawo ezishelelayo nezinto ezingabangela ukukhubeka.
- Uma unezingane ezincane, qiniseka ukuthi izindawo lapho zidlala khona futhi zichitha khona isikhathi ziphephile.
I-Anterior Pituitary iyi-gland encane kodwa enamandla ethonya izici eziningi zempilo yethu. Ngakho-ke uma unezimpawu ezintsha noma ezikhathazayo, ungacabangi nje ukuthi kuyinto ehlukile, kodwa khuluma nodokotela njalo. Bangathola isithombe esinembile sempilo yakho ngokuhlolwa okulula okumbalwa.
Umlayezo Wokuya Nawe Ekhaya
- I-Anterior Pituitary iyi-gland engangophizi, kodwa ebaluleke kakhulu, etholakala phansi kobuchopho bakho.
- Ikhiqiza ama-hormone ayisithupha alawula imisebenzi ebalulekile yomzimba njengokukhula, imetabolism kanye nokuzala.
- Izimo ezahlukene zezokwelapha zingavela ngenxa yokweqisa (i-hyperpituitarism) noma ukuntuleka (i-hypopituitarism) kwala ma-hormone.
- Kubaluleke kakhulu ukuvikela ikhanda, njengoba ukulimala ekhanda kungalimaza le ndlala.
- Uma unezimpawu ezihlobene nenkinga yama-hormone, ungangabazi ukubona udokotela wakho ngokushesha ukuze uthole iseluleko.
