Yintoni uvavanyo lwe-thyroxine (T4)?

Uvavanyo lwe-thyroxine lunceda ekuchongeni iingxaki ze-thyroid. Idlala lengqula yinto encinci, emile okwibhabhathane ekumqala womqala. Idlala lengqula lakho lenza iihomoni ezilawula indlela umzimba wakho osebenzisa ngayo amandla. Ikwadlala indima ebalulekileyo ekulawuleni ubunzima bakho, iqondo lobushushu emzimbeni, amandla emisipha, kwanemvakalelo yakho. I-Thyroxine, eyaziwa ngokuba yi-T4, luhlobo lwehomoni yedlala lengqula. Olu vavanyo lulinganisa inqanaba le-T4 egazini lakho. I-T4 eninzi kakhulu okanye encinci inokubonisa isifo se-thyroid.

Ihomoni ye-T4 iza ngeendlela ezimbini:

• T4 yasimahla, engena kwizicwili zomzimba apho kufuneka khona
• Ixabiso le-T4, ebambelela kwiiproteni, kuthintele ukuba zingangeni kwizicubu zomzimba

Uvavanyo olulinganisa zombini i-T4 yasimahla kunye ne-B4 ibizwa ngokuba luvavanyo olupheleleyo lwe-T4. Olunye uvavanyo lilinganisa i-T4 yasimahla. Uvavanyo lwe-T4 yasimahla luthathwa njengoluchanekileyo ngaphezu kovavanyo olupheleleyo lwe-T4 lokujonga ukusebenza kwe-thyroid.

Amanye amagama: i-thyroxine yasimahla, i-T4 yasimahla, ingqokelela ye-T4 iyonke, isikrini se-thyroxine, uxinzelelo lwe-T4 yasimahla

Isetyenziselwa ntoni?

Uvavanyo lwe-T4 lusetyenziselwa ukuvavanya ukusebenza kwe-thyroid kunye nokufumanisa isifo se-thyroid.

Kutheni ndifuna uvavanyo lwe-thyroxine?

Isifo se-Thyroid sixhaphake kakhulu kubafazi kwaye sihlala sikhona singaphantsi kweminyaka engama-40. Ikwayasebenza nasezintsatsheni. Unokufuna uvavanyo lwe-thyroxine ukuba ilungu losapho lakha lafumana isifo se-thyroid okanye ukuba uneempawu zokuba unehomoni yegazi egazini, imeko ebizwa ngokuba yi-hyperthyroidism, okanye iimpawu zokuba unehomoni encinci, imeko ebizwa ngokuba yihypothyroidism.

Iimpawu zehyperthyroidism, ekwabizwa ngokuba yi-thyroid engasebenziyo zibandakanya:

• Ixhala
• Ukuhla ukusinda
• Iinyikima ezandleni
• Ukunyuka kwentliziyo
• Ukukhukhumala
• Ukudumba kwamehlo
• Ingxaki yokulala

Iimpawu zehypothyroidism, ekwabizwa ngokuba yi-thyroid engasebenziyo zibandakanya:

• Ukutyeba kwakho
• Ukudinwa
• Ukulahleka kweenwele
• Ukunyamezelana kancinci kumaqondo obushushu abandayo
• Amaxesha okuya exesheni ngokungaqhelekanga
• Ukuqunjelwa

Kwenzeka ntoni ngexesha lovavanyo lwe-thyroxine?

Ingcali yokhathalelo lwempilo iyakuthatha isampulu yegazi kumthambo engalweni yakho, isebenzisa inaliti encinci. Emva kokuba inaliti ifakiwe, inani elincinci legazi liya kuqokelelwa kwityhubhu yovavanyo okanye igutyana. Unokuziva uluma kancinci xa inaliti ingena okanye iphuma. Oku kuhlala kuthatha imizuzu engaphantsi kwesihlanu.

Ngaba kuya kufuneka ndenze nantoni na ukulungiselela uvavanyo?

Awudingi naluphi na ulungiselelo olukhethekileyo lovavanyo lwegazi lwe-thyroxine. Ukuba umboneleli wakho wezempilo uyalele iimvavanyo ezingaphezulu kwisampulu yegazi lakho, unokufuna ukuzila ukutya (ungatyi okanye usele) iiyure ezininzi ngaphambi kovavanyo. Umboneleli wakho wezempilo uya kukwazisa ukuba ngaba kukho nayiphi na imiyalelo ekhethekileyo ekufuneka uyilandele.

Ngaba bukhona ubungozi kuvavanyo?

Mncinci kakhulu umngcipheko wokuvavanywa kwegazi. Unokuba nentlungu encinci okanye ukrakra kwindawo apho inaliti yafakwa khona, kodwa uninzi lweempawu zihamba ngokukhawuleza.

Zithetha ntoni iziphumo?

Iziphumo zakho zinokuza zikwimo yetotali iyonke, T4 yasimahla, okanye isalathiso sasimahla se-T4.

• Isalathiso simahla se-T4 siquka ifomula ethelekisa isimahla kunye nokubopha i-T4.
• Amanqanaba aphezulu alo naluphi na olu vavanyo (iyonke i-T4, i-T4 yasimahla, okanye isalathiso sasimahla se-T4) inokubonisa i-thyroid egqithisileyo, ekwabizwa ngokuba yi-hyperthyroidism.
• Amanqanaba asezantsi alo naluphi na olu vavanyo (iyonke i-T4, i-T4 yasimahla, okanye isalathiso sasimahla se-T4) anokubonisa i-thyroid engasebenziyo, ekwabizwa ngokuba yi-hypothyroidism.

Ukuba iziphumo zakho ze-T4 aziqhelekanga, umboneleli wakho wezempilo uya ku-odola iimvavanyo ezininzi ze-thyroid ukunceda ukuxilonga. Oku kunokubandakanya:

• Uvavanyo lwe-T3 hormone ye-thyroid. I-T3 yenye ihomoni eyenziwe yidlala lengqula.
• Uvavanyo lwe-TSH (idlala lengqula). I-TSH yincindi yedlala eyenziwe yindlala yebhinqa. Ikhuthaza i-thyroid ukuvelisa i-T4 kunye ne-T3 hormone.
• Uvavanyo lokufumanisa isifo se-Graves, isifo se-autoimmune esibangela i-hyperthyroidism
• Uvavanyo lokufumanisa isifo sikaHashimoto's thyroiditis, isifo esizenzekelayo esibangela i-hypothyroidism

Funda ngakumbi malunga novavanyo lwelabhoratri, uluhlu lweereferensi, kunye neziphumo zokuqonda.

Ngaba ikhona enye into endifuna ukuyazi malunga novavanyo lwe-thyroxine?

Utshintsho lwe-thyroid luyenzeka ngexesha lokukhulelwa. Nangona ingaqhelekanga, abanye abantu basetyhini banokuphuhlisa isifo se-thyroid ngexesha lokukhulelwa. I-Hyperthyroidism yenzeka malunga ne-0.1% ukuya kwi-0.4% yokukhulelwa, ngelixa i-hypothyroidism yenzeka malunga neepesenti ezi-2.5 zokukhulelwa.

I-Hyperthyroidism, kwaye ngokufuthi, i-hypothyroidism, inokuhlala emva kokukhulelwa. Ukuba uhlakulela imeko ye-thyroid ngexesha lokukhulelwa, umboneleli wakho wezempilo uya kubeka esweni imeko yakho emva kokuzalwa komntwana. Kwakhona, ukuba unembali yesifo se-thyroid, qiniseka ukuba uthetha nomboneleli wakho wezempilo ukuba ukhulelwe okanye ucinga ukukhulelwa.
