Uvavanyo lwegazi lwe-Antidiuretic

Uvavanyo lwe-Antidiuretic lwegazi lilinganisa inqanaba lehomoni ye-antidiuretic (ADH) egazini.

Isampulu yegazi iyafuneka.

Thetha nomboneleli wakho wezempilo malunga namayeza akho phambi kovavanyo. Amachiza amaninzi anokuchaphazela inqanaba le-ADH, kubandakanya:

• Utywala
• I-diuretics (iipilisi zamanzi)
• Amayeza oxinzelelo lwegazi
• I-insulin
• Amayeza okuphazamiseka kwengqondo
• Inikotini
• IiSteroids

Xa kufakwa inaliti ukutsala igazi, abanye abantu baziva iintlungu eziphakathi. Abanye baziva behlaba okanye behlaba kuphela. Emva koko, kunokubakho ukubetha okanye ukutyumza kancinci. Oku kuya kuhamba kungekudala.

I-ADH yihomoni eveliswa kwinxalenye yengqondo ebizwa ngokuba yihypothalamus. Emva koko iyagcinwa ize ikhutshwe kwilungu lobuchopho, incindi encinci emazantsi engqondo. I-ADH isebenza kwizintso ukulawula ubungakanani bamanzi aphuma kumchamo.

Uvavanyo lwegazi lwe-ADH luyalelwa xa umboneleli wakho ekrokrela ukuba unesifo esichaphazela inqanaba lakho le-ADH njenge:

• Ulwakhiwo lwamanzi emzimbeni wakho abangela ukudumba okanye ukudumba (i-edema)
• Umchamo ogqithisileyo
• Inqanaba lesodium (ityuwa) esegazini lakho
• Ukunxanwa okunzulu okanye okungalawulekiyo

Izifo ezithile zichaphazela ukukhutshwa okuqhelekileyo kwe-ADH. Inqanaba legazi le-ADH kufuneka lihlolwe ukufumanisa unobangela wesifo. I-ADH inokulinganiswa njengenxalenye yovavanyo lokuthintelwa kwamanzi ukufumana unobangela wesifo.

Amaxabiso aqhelekileyo e-ADH anokuvela kwi-1 kuye kwi-5 pg / mL (0.9 kuye ku-4.6 pmol / L).

Amaxabiso esiqhelo ahluka kancinci phakathi kweelebhu ezahlukeneyo.Ezinye iilebhu zisebenzisa imilinganiselo eyahlukeneyo okanye zinokuvavanya iisampulu ezahlukeneyo. Thetha nomboneleli wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Inqanaba eliphezulu kuneliqhelekileyo linokwenzeka xa kukhutshwa i-ADH eninzi, nokuba kubuchwephesha apho yenziwa khona, okanye kwenye indawo emzimbeni. Oku kubizwa ngokuba sisifo se-ADH esingafanelekanga (SIADH).

Izizathu ze-SIADH zibandakanya:

• Ukulimala kwengqondo okanye ukwenzakala
• Amathumba ebongo
• Ukungalingani kolwelo emva kotyando
• Usulelo kwingqondo okanye izicubu ezijikeleze ingqondo
• Usulelo kwimiphunga
• Amayeza athile, anje ngokuthimba iziyobisi, amayeza entlungu, kunye neyeza lokuthomalalisa uxinzelelo
• Umhlaza omncinci wesifo somhlaza wemiphunga
• Ukubetha

Inqanaba eliphezulu kune-ADH lingafunyanwa kubantu abanesifo sentliziyo, ukusilela kwesibindi, okanye ezinye iintlobo zesifo sezintso.

Inqanaba elisezantsi kuneliqhelekileyo linokubonisa:

• Ukonakaliswa kwehypothalamus okanye i-pituitary gland
• Isifo seswekile esiphakathi (insipidus) (imeko apho izintso zingakwaziyo ukugcina amanzi)
• Unxano olugqithisileyo (polydipsia)
• Ulwelo oluninzi kwimithambo yegazi (umthamo omkhulu)

Akukho mngcipheko ubandakanyekileyo ekuthatheni igazi lakho. Imithambo kunye nemithambo iyahluka ngobukhulu ukusuka komnye umntu ukuya komnye, kwaye ukusuka kwelinye icala lomzimba ukuya kwelinye. Ukuthatha igazi kwabanye abantu kunokuba nzima ngakumbi kunabanye.

Eminye imingcipheko enxulumene nokutsalwa kwegazi incinci, kodwa inokubandakanya:

• Ukopha kakhulu
• Ukufa isiqaqa okanye ukuziva ungenantloko
• Ukugqobhoza okuninzi ukufumana imithambo
• I-Hematoma (igazi eliqokelela phantsi kwesikhumba)
• Usulelo (umngcipheko omncinci nangaliphi na ixesha ulusu lwaphukile)
