I-Thyroxine (T4) yi-hormone ephambili eveliswa yi -thyroid gland , ilungu elimile okwebhabhathane eliphambi kwentamo yethu, ngakumbi elijikeleze umbhobho womoya. Eli gland lincinci lilawula iinkqubo ezininzi ezibalulekileyo emzimbeni wethu.- Isantya esiguqula ngaso ukutya esikutyayo sibe ngamandla ( iMetabolism )
- Isantya sokuhamba kokutya kwinkqubo yokugaya ukutya

- Izinga apho iiseli emzimbeni zifa kwaye kwakheka iiseli ezintsha
Gqirha, kutheni ucela ukuba ndenze uvavanyo lwe-T4?
Kukho izizathu ezahlukeneyo zokuba ugqirha wakho angacebisa uvavanyo lwegazi lwe-T4.- Ukuchonga izifo ze-thyroid : Olu vavanyo lubalulekile ekuchongeni iimeko ezifana ne-hypothyroidism okanye i-hyperthyroidism kunye nokujonga imeko ngexesha lonyango.
- Chonga iingxaki nge-pituitary gland: I-pituitary gland esebuchotsheni bethu ivelisa i-hormone ebizwa ngokuba yi-TSH (i-Thyroid-Stimulating Hormone). Le hormone ye-TSH ixelela i-thyroid gland ukuba ingakanani i-T4 kunye ne-T3 ekufuneka yenziwe. Ngoko ke, uvavanyo lwe-T4 lukwanceda ukubona ukuba kukho ingxaki nge-pituitary gland.
- Ezinye izizathu: Ezinye ezifana ne-TSH okanye i-T3Ukuba kukho izinto ezingaqhelekanga kwiimvavanyo ze-thyroid, ukuba kukho iqhubu kwi-thyroid gland, ukuba i-gland idumbile, okanye ukuba unengxaki yokukhulelwa umntwana, ungacelwa ukuba wenze uvavanyo lwe-T4 ukuze ubone ukuba i-thyroid yakho isebenza njani kanye kanye.
| Imeko ye-thyroid | Iimpawu eziqhelekileyo |
|---|---|
| Amanqanaba e-T4 aphantsi (i-Hypothyroidism) Ukucothisa ukusebenza komzimba | Uxinzelelo olukhulu, ukulahlekelwa yinkumbulo kunye nengqalelo, ukudumba okujikeleze amehlo, ukulahleka kweenwele, ukudumba kwe-thyroid gland (i-goiter), ukudinwa kakhulu, ukungakwazi ukunyamezela ingqele, ukunyuka kobunzima, ukungabi namdla wokutya, ulusu olomileyo nolubandayo, ukubetha kwentliziyo okucothayo, ubunzima bokuphefumla, ukuqhina, imijikelo yokuya exesheni engaqhelekanga kubafazi. |
| Ukwanda kwamanqanaba e-T4 (i-Hyperthyroidism) Ukusebenza komzimba okukhawulezileyo | Ukucaphuka rhoqo nokungazoli, ukungalali, amehlo avuvukileyo (isifo samehlo sikaGraves), ukwehla kobunzima, indlala egqithisileyo, ukunganyamezelani nobushushu, ukubila okugqithisileyo, ukungcangcazela kweminwe, intloko, okanye ubuso, ukubetha kwentliziyo ngokukhawuleza okanye okubuhlungu, uxinzelelo lwegazi oluphezulu, urhudo. |

Zithini ii-Free T4 kunye nee-Bound T4?
Kukho iintlobo ezimbini ze-hormone ye-T4 emzimbeni wethu.- I-T4 yasimahla: Le yi-T4 ejikeleza ngokukhululekileyo egazini, ingabotshelelwanga kuyo nayiphi na into. Le yi-T4 enokungena kwiiseli kwaye isetyenziswe nangaliphi na ixesha.
- I-T4 ebotshelelweyo: Ezi zibotshelelweyo kwiiproteni kwaye zihamba egazini. Ezi proteni zinceda i-hormone ye-T4 ukuba ithuthwe ngokukhuselekileyo ukuya apho ifunekayo khona, ngaphandle kokufunxwa zezinye iiseli endleleni. Uninzi lwe-T4 emzimbeni wethu lubotshelelwe kwi-T4.
Oogqirha badla ngokujonga inqanaba le-Free T4 kuba lixabiso le-T4 elinokusetyenziswa ngumzimba, kwaye linika umbono ongcono wokuba i-thyroid isebenza kakuhle kangakanani.
Izinto ekufuneka uziqwalasele ngaphambi kovavanyo
Ngaphambi kokuba wenze uvavanyo lwegazi, kubalulekile ukuxelela ugqirha wakho malunga namayeza, iivithamini, okanye izongezo ozithathayo. Amanye amayeza, afana namayeza okulwa nokuxhuzula, amayeza entliziyo, kunye neepilisi zokulawula ukuzalwa, anokuchaphazela iziphumo zakho ze-T4. Ingakumbi ukuba uthatha isongezelelo se-biotin , singenza amanqanaba akho e-T4 abonakale ephezulu kunokuba enjalo ngokwenene. Oku kunokubangela ukuba ugqirha wakho angayiboni ingxaki ye-thyroid. Kwakhona xelela ugqirha wakho ukuba ukhulelwe okanye unezinye iimeko zonyango, ezifana nesifo sezintso.Ngaba kukho naziphi na iingozi kuvavanyo lwegazi lwe-T4?
Olu luvavanyo oluqhelekileyo, njengalo naluphi na olunye uvavanyo lwegazi. Umntu oqeqeshiweyo usebenzisa inaliti encinci ukuthabatha igazi elincinci kumthambo osengalweni yakho aze afake isiqwenga kuloo ndawo.
