Ingabe unesisindo esiningi ngokweqile, isifo sokuphela sokukhathala, umfutho wegazi ophansi? Kukhona ithuba lokwenza ukuhlolwa kwegazi kwamahomoni. Ngokuvamile, imbangela yempilo empofu yizinga eliphakanyisiwe noma eliphansi lomunye wabo. Isibonelo, i-hormone thyroxin inomthwalo wemetabolism, ithoni yomzimba nezinye izinto ezibalulekile.
Imisebenzi ye-hormone thyroxine
I-hormone ye-thyroid i-thyroxine ibhekisela kwenye ye-hormone ezimbili ezinkulu umzimba oveza. Ngokuphuza, ngezinye izikhathi kuthiwa yi-T4. Ngaphandle kwe-thyroxine, i-gland yegciwane iveza ama-hormone amaningi angu-8, kodwa isabelo sabo ku-10% kuphela. Konke okunye ku-thyroxine, enezindawo ezinjalo:
- ilawula izinga lomfutho wegazi;
- obhekene nezwi le-muscle;
- kwandisa umsebenzi womzimba nengqondo;
- ikhuthaza ukungena kwe-oxygen ngamalungu;
- kushukumisa ukucabanga;
- kusheshisa umzimba ;
- kwandisa inani lama-caroles enhliziyo;
- obhekene nokukhiqizwa kwe-hormone erythropoietin, ukwakhiwa kwama-erythrocyte nokufaniswa kwamaprotheni.
Abagijimi abaningi kanye nabesifazane abathile bathatha izithako zemvelo nezakhi zokwelapha ze-thyroxine ukunciphisa isisindo somzimba futhi ukwandise ukudla okune-caloric nsuku zonke. Nokho, umuntu kufanele acabange ukuthi insalela ye-thyroxin iyingozi njengokuntuleka kwayo:
- ukujuluka okukhulu;
- umuntu uyathukuthela futhi ulaka;
- kukhona ukuleleka;
- ingozi eyengeziwe ye-tachycardia nezinye izifo zenhliziyo;
- i-resorption yamathambo iqala.
Ungakhuphula kanjani noma ukwandise i-hormone i-thyroxine nokuthi ngabe kuyadingeka yini ukuyenza noma ukuyenza?
Ngaphambi kokuba uphendule lo mbuzo, sifuna ukukhuluma ngalokho okungaba imiphumela ye-hormone thyroxin eyancishiswa. Okuyingozi kakhulu ukuthuthukiswa kwe-hypothyroidism (ukunciphisa i-thyroxine) ezinsaneni, kungabangela ukuwohloka komqondo kanye ne-cretinism, kanye nokukhubazeka okuvamile cishe yonke imisebenzi yomzimba. Ngakho-ke, abantwana, abazalwa lapho beba nokusola kokuntuleka kwaleli hormone, cishe ngosuku lwe-4th-5 lokuphila, igazi lithathwa ukuze lihlaziywe. Kubantu abadala, i-hypothyroidism ibangela izifo ezinjalo:
- ukunciphisa kwemisebenzi yengqondo;
- ischemia;
- i-bradycardia;
- i-hypotension ;
- ukuphazanyiswa komgudu wamathumbu;
- kunciphise umsebenzi wokuzala.
Njengoba i-thyroxine i-hormone yegazi yamahhala, kodwa ingaba nesifundazwe esihlotshaniswa namaprotheni, zonke izinhlelo zomzimba kanye ne-gland gland ziqala ukusebenza ngokuphumelelayo ngemva kwamasonto amabili ngemuva kokujwayelekile izinga layo. I-hormone hormone thyroxine ayiyona inqwaba enzile futhi ingashintsha ngaphakathi kwamanani amaningana kumuntu ngamunye.
Njengoba i-hormone ye-T4 ihluke kwenye i-hormone ye-thyroid eyisisekelo, i-T3, ukuba khona kwe-molecule ye-iodine ekubunjweni, izinga le-thyroxin lihlobene ngokuqondile nenani laleli phuzu elilandelanayo emzimbeni kanye nokufana kwalo. Uma i-iodine ingenayo ngokwanele, i-thyroxine yehla. Ngokweqile kwalesi sici, isifo se-Graves siqala - ubufakazi obuphezulu kakhulu kwezinga lakho le-thyroxin
Endabeni lapho ukudla okune-iodine kungathinti ukukhiqizwa kwe-thyroxine, ukuhlolwa kwezokwelapha kufanele kwenziwe futhi imbangela enqunywe. Udokotela kumele enze lokhu. Yena, uma kunesidingo, uzobeka i-thyroxine kumathebulethi. Isimiso se-thyroxine kubantu besifazane sinqunywa ngemuva kokuhlolwa okuningiliziwe kwegazi kuma-hormone amakhulu, emva kwalokho ungase uqale ukwamukela okunye komunye wabo. Izidakamizwa ezifana ne-thyroxine kufanele zisetshenziswe nsuku zonke nangesikhathi eside. Lokhu kukuvumela ukuba ulungise ibhalansi ye-hormonal.
