Kalula nje, iyini i-thyroxine (T4)?
I-Thyroxine (T4) iyi-hormone enkulu ekhiqizwa yi -thyroid gland , isitho esimise okwebhabhathane esitholakala ngaphambili entanyeni yethu, ikakhulukazi eduze komphimbo. Le gland encane ilawula izinqubo eziningi ezibalulekile emzimbeni wethu.- Izinga esiguqula ngalo ukudla esikudlayo kube amandla ( Metabolism )

- Indlela imisipha efinyela ngayo
- Izinga lokufa kwamaseli emzimbeni kanye nokwakheka kwamaseli amasha
Dokotela, kungani ungicela ukuthi ngenze ukuhlolwa kwe-T4?
Kunezizathu eziningana zokuthi kungani udokotela wakho engase ancome ukuhlolwa kwegazi kwe-T4.- Ukuhlonza izifo ze-thyroid : Lokhu kuhlolwa kubalulekile ekuhlonzeni izimo ezifana ne-hypothyroidism noma i-hyperthyroidism kanye nokuqapha isimo ngesikhathi sokwelashwa.
- Thola izinkinga ngendlala ye-pituitary: Indlala ye-pituitary ebuchosheni bethu ikhiqiza i-hormone ebizwa ngokuthi i-TSH (i-Thyroid-Stimulating Hormone). Le hormone ye-TSH itshela indlala ye-thyroid ukuthi ingakanani i-T4 ne-T3 okufanele iyenze. Ngakho-ke, ukuhlolwa kwe-T4 kusiza futhi ukubona ukuthi kunenkinga ngendlala ye-pituitary.
- Ezinye izimbangela: Ezinye ezifana ne-TSH noma i-T3Uma kukhona ukungahambi kahle ekuhlolweni kwe-thyroid, uma kukhona iqhubu endlaleni ye-thyroid, uma indlala ivuvukele, noma uma unenkinga yokukhulelwa umntwana, ungase ucelwe ukuthi wenze isivivinyo se-T4 ukuze kutholakale ukuthi i-thyroid yakho isebenza kanjani kahle.
| Isimo se-thyroid | Izimpawu ezivame ukubonakala |
|---|---|
| Amazinga e-T4 aphansi (i-Hypothyroidism) Ukunciphisa ukusebenza komzimba | Ukucindezeleka okukhulu, ukulahlekelwa inkumbulo nokunaka, ukuvuvukala okuzungeze amehlo, ukulahlekelwa izinwele, ukuvuvukala kwendlala yegilo (i-goiter), ukukhathala okukhulu, ukungakwazi ukubekezelela umkhuhlane, ukukhuluphala, ukulahlekelwa yisifiso sokudla, isikhumba esomile nesibandayo, ukushaya kwenhliziyo okuhamba kancane, ubunzima bokuphefumula, ukuqunjelwa, imijikelezo yokuya esikhathini engajwayelekile kwabesifazane. |
| Amazinga e-T4 akhuphukile (i-Hyperthyroidism) Ukusebenza komzimba okusheshayo | Ukucasuka njalo nokungahlaliseki, ukuqwasha, amehlo avuvukele (isifo samehlo sikaGraves), ukwehla kwesisindo, indlala enkulu, ukungabekezelelani nokushisa, ukujuluka ngokweqile, ukuthuthumela kweminwe, ikhanda, noma ubuso, ukushaya kwenhliziyo okusheshayo noma okushaya ngamandla, umfutho wegazi ophakeme, isifo sohudo. |

Yini i-Free T4 kanye ne-Bound T4?
Kunezinhlobo ezimbili ze-hormone ye-T4 emzimbeni wethu.- I-T4 yamahhala: Lena yi-T4 ejikeleza ngokukhululeka egazini, ingaboshelwe kunoma yini. Lena yi-T4 engangena emaseli futhi isetshenziswe nganoma yisiphi isikhathi.
- I-T4 eboshiwe: Lezi ziboshiwe kumaprotheni futhi zihamba egazini. Lawa maprotheni asiza i-hormone ye-T4 ukuthi ithuthwe ngokuphephile iye lapho idingeka khona, ngaphandle kokumuncwa amanye amangqamuzana endleleni. Iningi le-T4 emzimbeni wethu liboshiwe ku-T4.
Odokotela bavame ukubheka izinga le-Free T4 ngoba liyinani le-T4 umzimba ongalisebenzisa, futhi linikeza umbono omuhle kakhulu wokuthi i-thyroid isebenza kahle kangakanani.
Izinto okufanele uzicabangele ngaphambi kokuhlolwa
Ngaphambi kokuhlolwa kwegazi, kubalulekile ukutshela udokotela wakho nganoma yimiphi imithi, amavithamini, noma izithasiselo ozithathayo. Eminye imithi, njengemithi yokulwa nokuquleka, imithi yenhliziyo, kanye namaphilisi okulawula ukuzalwa, ingathinta imiphumela yakho ye-T4. Ikakhulukazi uma uthatha isithasiselo se -biotin , singenza amazinga akho e-T4 abonakale ephakeme kunalokho ayikho ngempela. Lokhu kungabangela udokotela wakho ukuthi aphuthelwe inkinga ye-thyroid. Tshela nodokotela wakho uma ukhulelwe noma unezinye izimo zezokwelapha, njengesifo sezinso.Ingabe kukhona izingozi zokuhlolwa kwegazi le-T4?
Lokhu ukuhlolwa okuvamile, njenganoma yikuphi ukuhlolwa kwegazi. Umuntu oqeqeshwe usebenzisa inalithi encane ukuthatha inani elincane legazi emthanjeni osengalweni yakho bese efaka i-patch endaweni. Izingozi zincane kakhulu, kodwa ngezinye izikhathi okulandelayo kungenzeka:- Ubuhlungu obuncane lapho inaliti ifakiwe khona.
- Ukopha okuncane
- Ukuphuka (igazi lihlangana ngaphansi kwesikhumba)
- Uma unganakekeli ukuhlanzeka, ungathola ukutheleleka.
- Isiyezi noma ukuquleka
Ukuqonda imiphumela yokuhlolwa kwe-T4
Amabanga ajwayelekile okuhlolwa kwe-Free T4 angahluka kancane kuye ngobudala, ubulili, kanye nelebhu eyenza ukuhlolwa. Kodwa-ke, ngokuvamile, amanani ajwayelekile alandelayo: Kwabomama abakhulelwe
Into ebaluleke kakhulu ukuthi udokotela wakho kuphela ongachaza amanani akulo mbiko ngendlela evumelana nesimo sakho. Ngakho-ke, qiniseka ukuthi uyawuthatha umbiko bese ubona udokotela wakho.| Iqembu lobudala / isimo | Ibanga Elijwayelekile le-T4 yamahhala (ng/dL) |
|---|---|
| Izingane ezineminyaka engu-5 ubudala | 0.8 - 2.8 |
| Izingane ezineminyaka engu-6-15 ubudala | 0.8 - 2.1 |

| Izinyanga zesibili nezesithathu | 0.7 - 1.20 |
Izimbangela zamazinga aphansi e-T4 (i-Hypothyroidism)
- I-Hashimoto's thyroiditis: Lesi yisifo esibangelwa ukuzivikela komzimba. Lokhu kusho ukuthi amasosha ethu omzimba ahlasela i-thyroid gland ngephutha.
- Ukuntuleka kwe-iodine ekudleni.
- Izifo ezithathelwanayo zesikhathi esifushane.
- Ukungondleki kahle.
- Eminye imithi.
Izimbangela zokwanda kwamazinga e-T4 (i-Hyperthyroidism)
- Isifo sikaGraves: Lesi futhi yisifo sokuzivikela komzimba.

- Amaqhubu angewona umdlavuza (izimila/amaqhubu angewona awemvelo) endlaleni yegilo.
- Ukuvuvukala kwendlala yegilo (i-Goiter).
- Ukwandisa umthamo wemithi ye-thyroid hormone esetshenziselwa ukwelashwa.
Ukuhlolwa okwengeziwe
Nakuba ukuhlolwa kwe-T4 kungabonisa ukuthi kunenkinga nge-thyroid gland yakho, akukwazi ukukutshela ngqo ukuthi yini ebangela lokho. Ngakho-ke, uma izinga lakho le-T4 lingajwayelekile, udokotela wakho cishe uzoyala ukuhlolwa okwengeziwe ukuthola imbangela.- Ukuhlolwa kwegazi le-TSH: Lokhu kuvame ukuba ukuhlolwa kokuqala okwenziwayo. Amazinga e-TSH ne-T4 ahlobene ngqo.
- Ukuhlolwa kwegazi kwe-T3 kwamahhala: Kuhlola izinga lenye i-hormone eyinhloko eyenziwe yi-thyroid gland.
- Ukuhlolwa kwama-antibodies e-thyroid: Hlola isifo esifana nesikaHashimoto noma sikaGraves.
- Isithombe sokuthathwa kwe-iodine emisebeni: Bona indlela i-thyroid gland emunca ngayo i-iodine.
Umlayezo Wokuya Nawe Ekhaya
- Ukuhlolwa kwegazi le-T4 kuwukuhlolwa okubalulekile okuhlola ukuthi indlala yakho yegilo isebenza kahle kangakanani.
- Amazinga aphansi e-T4 abizwa ngokuthi i-Hypothyroidism, kanti amazinga aphezulu e-T4 abizwa ngokuthi i-Hyperthyroidism. Zombili lezi zimo zinezimpawu ezihlobene.
