Ngaba ugqirha wakho ubhale "uVavanyo lwe-T4" kuvavanyo lwegazi oluthathiweyo? Okanye ucinga ukuba unengxaki nge-thyroid gland yakho? Mhlawumbi ulahlekelwa bubunzima okanye utyeba ngendlela engachazekiyo, uziva udiniwe ngalo lonke ixesha, okanye uzive ungaphilanga? Ngoko ke namhlanje, masithethe ngokulula nangobubele ngolu vavanyo lwe-T4 kunye noko lusixelela kona ngemizimba yethu.
Okokuqala, masibone, yintoni le vavanyo ye-T4?
Ngamafutshane, uvavanyo lwe-T4 luvavanyo lwegazi olujonga indlela esebenza ngayo i-thyroid gland yakho.
Khawucinge nje, i-thyroid gland sisitho esincinci esimile okwebhabhathane esikwindawo engaphambili entanyeni yethu, ngaphezulu nje kwe-collarbone. Le yinxalenye ebaluleke kakhulu kwinkqubo ye-endocrine yomzimba wethu, oko kukuthi, inkqubo evelisa iihomoni. Le gland yenza iihomoni ze-thyroid ize izikhuphele egazini. Ezi homoni emva koko zihamba emzimbeni wonke ngegazi kwaye ziyalele amalungu ahlukeneyo ukuba "enze oku nokuya."
I-Thyroxine, okanye i-T4 , yeyona hormone iphambili eveliswa yi-thyroid gland. Ngoko ke ukuba i-T4 hormone iphezulu kakhulu okanye iphantsi kakhulu emzimbeni, oko kusinika umbono wokuba kukho uhlobo oluthile lwesifo kwi-thyroid gland.
I-T4 yasimahla kunye ne-Bound T4: Yintoni umahluko phakathi kwezi zimbini?
Oogqirha bajonga amanqanaba e-T4 ngovavanyo lwegazi. Kodwa le hormone ye-T4 ikhona egazini lethu ngeendlela ezimbini:
- I-T4 ebotshelelweyo: Oku kufana nepasela ebotshelelwe ngokuqinileyo ngeentambo kwilori. Le hormone ye-T4 ibotshelelwe kwiiproteni. Ke ngoko, ayinakungena ngqo kwiiseli zomzimba wethu (iithishu) ize isebenze.
- I-T4 yasimahla: Le yeyona nto inzima. Njengezinto ezakhutshwa kwilori, ezikhutshwe kwiphakheji. Ezi hormone ze-T4 "zikhululekile" egazini, azibotshelelwanga kwiiproteni. Ngoko ke zinokungena ngqo kwiiseli zethu kwaye zenze umsebenzi wazo.
Ngenxa yolu mahluko, kukho iintlobo ezahlukeneyo zovavanyo ezilinganisa amanqanaba e-T4. Uvavanyo olulinganisa zombini ezi ntlobo kunye lubizwa ngokuba luvavanyo lwe-T4 epheleleyo . Nangona kunjalo, amaxesha amaninzi, oogqirha bajonga kuphela amanqanaba e-T4 asimahla . Ngenxa yokuba yi-T4 yasimahla echaphazela imizimba yethu, ukuyilinganisa kunokunika umfanekiso ochanekileyo wokusebenza kwe-thyroid gland.
Ugqirha wakho uhlala eyalela uvavanyo lwe -TSH (iHormone evuselela iThyroid) kunye novavanyo lwe-T4. I-TSH yihomoni eveliswa yi-pituitary gland engqondweni yethu. Yiyo exelela i-thyroid gland ukuba ivelise i-T4 kunye ne-T3. Kuphela xa udibanisa amaxabiso ezi vavanyo zombini apho unokufumana umfanekiso opheleleyo wemeko yakho.
Yintoni kanye kanye le hormone ye-T4 (thyroxine) eyenzayo emzimbeni?
Njengoko besitshilo ngaphambili, i-thyroxine (T4) yeyona hormone iphambili eveliswa yi-thyroid gland. Ukongeza, ikwavelisa amanani amancinci e -triiodothyronine , okanye i-T3 . Xa zidibene, i-T4 kunye ne-T3 zisebenza njenge "hormones ze-thyroid."
Cinga ngayo, i-T4 'ayisebenzi' kancinci, oko kuthetha ukuba ayisebenzi kangako. Kodwa xa ifika kwisibindi nezintso zethu, uninzi lwale T4 luguqulwa lube yi-T3, 'esebenzayo', oko kuthetha ukuba ngumsebenzi wokwenene. Ngoko ke yi-T3 engena kwiiseli zethu kwaye inefuthe elikhulu.
Xa zizonke, i-T4 kunye ne-T3 zilawula imisebenzi emininzi ebalulekileyo emzimbeni wethu:
- Izinga le-metabolic: Ngamafutshane, izinga esiguqula ngalo ukutya esikutyayo sibe ngamandla. Ukuba oku kuyanda, sinciphisa ubunzima; ukuba kuyancipha, sifumana ubunzima.
- Umsebenzi wentliziyo kunye nenkqubo yokwetyisa: Isantya esibetha ngaso intliziyo yethu kunye nendlela amathumbu ethu asebenza ngayo kuyayichaphazela le nto.
- Ukulawula izihlunu: Kubalulekile ukuze izihlunu zibe namandla kwaye zisebenze kakuhle.
- Uphuhliso lobuchopho: Yihomoni ebalulekileyo ekuphuhlisweni kobuchopho, ingakumbi kubantwana abancinci.
- Impilo yamathambo: Inceda ukugcina amathambo eqinile.
I-thyroxine yokwenziwa
I-thyroid gland yabanye abantu ayivelisi i-T4 hormone eyaneleyo. Le meko siyibiza ngokuba yi-hypothyroidism . Oogqirha banika aba bantu ipilisi equlethe i-T4 hormone yokwenziwa. Ibizwa ngokuba yi -levothyroxine . Ikwasetyenziswa emva kotyando lweminye imidlaza ye-thyroid.
Kutheni kufuneka ndenze uvavanyo lwe-T4?
Kukho izizathu ezahlukeneyo zokuba ugqirha wakho angayalela uvavanyo lwe-T4. Oku kudla ngokwenziwa ukuze kufunyanwe umbono wokuba i-thyroid yakho isebenza kakuhle kangakanani.
Nazi ezinye zezizathu eziphambili:
- Ukuba ufumana ingxelo ye-TSH engaqhelekanga: Ukuba iziphumo zakho zangaphambili zovavanyo lwe-TSH bezingekho phakathi koluhlu oluqhelekileyo, kuya kwenziwa uvavanyo lwe-T4 ukuze kufunyanwe unobangela.
- Ukuchonga izifo ze-thyroid: Olu vavanyo lubalulekile ekuxilongeni i-hyperthyroidism, imeko apho i-thyroid gland isebenza kakhulu, okanye i-hypothyroidism, i-thyroid gland engasebenzi kakuhle .
- Ukujonga unyango: Ukuba sele usebenzisa unyango lokutshintshwa kweehomoni kwimeko ye-thyroid, ugqirha wakho uya kwenza olu vavanyo rhoqo ukuze abone ukuba umthamo wamayeza owasebenzisayo ufanelekile na emzimbeni wakho.
- Kwiintsana ezisandul’ ukuzalwa: Olu vavanyo ngamanye amaxesha lwenziwa ukujonga ukusebenza okuphantsi kwe-thyroid kwiintsana ezisandul’ ukuzalwa.
- Kwezinye iimeko:Olu vavanyo lunokunceda ekufumaneni iimeko ezirhanelekayo ezifana ne -goiter , amaqhuqhuva e-thyroid , iingxaki ze-pituitary okanye ze-hypothalamus.
Ndilungiselela njani uvavanyo? Kwenzeka ntoni xa ndinikela ngegazi?
Akufuneki kulungiswa okukhethekileyo kuvavanyo lwe-T4. Ungatya kwaye usele ngokuqhelekileyo ngaphambi kokuba unike igazi. Nangona kunjalo, amanye amayeza okanye iivithamini ozithathayo zinokuchaphazela iziphumo zovavanyo. Ngoko ke, kubaluleke kakhulu ukuxelela ugqirha wakho ngawo onke amayeza owathathayo.
Khumbula ngokukodwa: Ukuba uthatha i-vitamin equlethe i-biotin (efumaneka rhoqo kwizongezo zesikhumba, iinwele, kunye neenzipho), kufuneka uyeke ukuyithatha ubuncinci iintsuku ezi-3-5 ngaphambi kokuba unikele ngegazi. Ngaphandle koko, amanqanaba akho e-thyroid hormone anokuba phezulu okanye aphantsi ngokwengxelo, nokuba aqhelekile. Oku kubaluleke kakhulu.
Akukho sizathu sokoyika ukunikela ngegazi. Yinkqubo elula kakhulu ethatha ngaphantsi kwemizuzu emihlanu:
1. Uza kuhlaliswa esitulweni kwaye kuza kufumaneka umthambo olungileyo, odla ngokuba ngaphakathi kwengqiniba yakho.
2. Indawo icocwa ngeqhekeza elincinci lekotoni, kwaye kufakwa inaliti encinci kakhulu emthanjeni. Uya kuziva intlungu encinci, njengembovane encinci ekulunywayo.
3. Emva koko, inani elifunekayo legazi liqokelelwa kwityhubhu encinci.
4. Nje ukuba igazi litsalwe, inaliti iyasuswa kwaye iqhekeza lekotoni libekwe phezu kwendawo kwaye licinezelwe. Emva koko kufakwa iplasta encinci kuloo ndawo. Yiyo leyo!
Uyiqonda njani le ngxelo?
Ngokwesiqhelo ungafumana ingxelo yakho kungekapheli usuku okanye ezimbini. Ingxelo iya kubhala ixabiso lakho le-Free T4, kunye "noLuhlu oluQhelekileyo/uLuhlu lweeReferensi" kolo vavanyo.
Kubalulekile: Uluhlu oluqhelekileyo olunikwa ziilabhoratri ezahlukeneyo lunokwahluka kancinci, ngoko ke soloko uthelekisa iziphumo zakho noluhlu oluqhelekileyo kwingxelo yakho.

- Ukuqhinwa.
Kwenzeka ntoni xa uthelekisa ixabiso le-T4 kunye ne-TSH?
Le yeyona ngongoma ibalulekileyo. Ugqirha ufikelela kwisigqibo malunga nengxaki ye-thyroid ngokujonga iingxelo ze-T4 kunye ne-TSH kunye. Kuba kukho ubudlelwane obuqinileyo phakathi kwezi zimbini.
Ungayiqonda ngokulula le theyibhile.
| Inqanaba le-TSH | Inqanaba le-T4 | Oku kungafundwa ngolu hlobo lulandelayo: |
|---|---|---|
| Phezulu | Iphantsi | Le yeyona meko ixhaphakileyo kwi -hypothyroidism . Ngenxa yokuba i-thyroid gland ayenzi i-T4 eyaneleyo, ingqondo iyayikhwaza ithi "isebenze nzima!" kwaye ikhupha i-TSH eninzi kakhulu. |
| Iphantsi | Phezulu | Le yeyona meko ixhaphakileyo kwi -hyperthyroidism . Ngenxa yokuba i-thyroid gland ivelisa i-T4 eninzi, ingqondo iyayeka ukuvelisa i-TSH. |
| Phezulu | Eqhelekileyo | Oku kubizwa ngokuba yi -Subclinical Hypothyroidism . Oku kuthetha ukuba i-thyroid gland iqala ukusebenza kancinci, kwaye ingqondo kufuneka ikhuphe i-TSH engaphezulu ukuze iyilawule. Iimpawu zisenokuba azikaqali okwangoku. |
| Iphantsi | Eqhelekileyo | Oku kubizwa ngokuba yi -Subclinical Hyperthyroidism . I-thyroid gland isebenza kakhulu kancinci. Ngenxa yoko, ingqondo iyanciphisa ukukhutshwa kwe-TSH. Oku kusenokungabi nazimpawu. |
| Iphantsi | Iphantsi | Le yimeko engaqhelekanga kancinci. Oku kuthetha ukuba ingxaki isenokungabi kwi-thyroid gland, kodwa ikwi-pituitary gland esebuchotsheni. Ekubeni loo gland ingayivelisi kakuhle i-TSH, i-thyroid gland nayo ayivelisi i-T4. |
Nceda ungoyiki ukuba ubona ixabiso elingaqhelekanga kwingxelo yakho. Isifo se-thyroid sisifo esixhaphakileyo namhlanje, kwaye sinokunyangwa kwaye silawulwe ngempumelelo. Ngugqirha wakho kuphela onokukunika icebiso elifanelekileyo ngentsingiselo yengxelo yakho kunye nento omawuyenze ngokulandelayo.
