Ukuqubuka kwegazi kuyenzeka lapho i-capillaries yegazi iphuka kanye nokuphuma kwama-erythrocyte ngaphezu kwezimpahla. Ezimweni eziningi, ukuqhuma akukwenzeki, ngaphandle kokuvuvukala kwezindonga zemikhumbi. Kusuka kwezinye izilonda ezifanayo, ukuqhuma okumnyama kuhlukahluka ngokuthi akuguquki futhi akupheli uma ucindezelwe. Ukubonakala kwe-rash kubangelwa izimbangela zokubonakala kwayo, ngezifo ezihlukahlukene kungaba nobukhulu obuhlukahlukene kanye nemibala. Ukuqhuma kungahle kube uhlobo lwezingcezu ezincane, amachashazi noma amabala amakhulu okubomvu, obomvu, obomvu, obuluhlaza noma omnyama. Izinsalela ezincane zibizwa ngokuthi i-petechiae, izindawo ezinkulu zibizwa nge-purpura noma i-ecchymosis. Okuvame kakhulu ukuqhuma okukhulu emilenzeni, okungahlushwa ukuxilongwa, ngoba indawo enjalo isici sezifo eziningi.
Kungakhathaliseki isimo esijwayelekile kanye nokutholakala kwezinye izibonakaliso zesifo, ukubonakala kokushona okukhulu kokubili kwezingane kanye nabantu abadala kubonisa isidingo sokwelashwa ngokushesha ukuze uthole usizo lokuqala kanye nokukhomba izimbangela zokuhlukumeza.
Izimbangela zokuqhaqhazela okukhulu
Isimbangela sokuqhaqhazela kwamanzi kungaba izifo ezithathelwanayo nezifo ezithathelwanayo, i-steroids, kanye nezifo ezihlukahlukene ezithinta imithwalo yegazi. Izinguquko zomdala nazo zingaholela ekubukeni kwezindawo ezivuthayo. Isizathu esivamile sokuqhaqhazela kwezingane ezineminyaka engaphansi kweminyaka emihlanu yisimo esibi se-vasculitis, isifo se-microvessel. I-vasculitis ene-Hemorrhagic, evame ukuhambisana nokuqhuma okukhulu emilenzeni. Ukwelashwa kunqunywe kuye ngokuthi ubukhulu nesimo sesifo. Njengomthetho, izingane ngesikhathi sonyango zibhekwa ngaphansi kwesikhalazo. Njengoba ukwelashwa okufanele futhi okufika ngesikhathi, lesi sifo sinomphumela omuhle.
Ngokufanayo, lapho kuqhuma ukulimala kwezingane, izifo ezinjenge-hemophilia nesifo sikaV von Willebrand kufanele zisuswe. I-Hemophilia ibonakala ngokubonakala kwe-hematomas engaphansi, kanti noma yikuphi ukulimala kuhambisana nokuphuma kwegazi ngaphakathi nangaphandle. Ngokuyinhloko, i-hemophilia ithinta amadoda. Izifo zikaWillebrand ziholela ekukhuphukeni kwe-capillaries, okubangela ukubukeka kwesisu.
Izifo ezinzulu ezifana ne-amyloidosis, i-wegener's granulomatosis, i-thrombocytopenic purpura, ihambisane nezinhlobo ezihlukahlukene zokuqhwala okukhulu, futhi zidinga ukwelashwa ngokushesha.
I-Hemosiderosis yesikhumba nayo ihambisana nokubonakala kwe-rash, okushintsha umbala kusuka obomvu kuya ophuzi noma obomvu ngemva kwesikhathi.
Phakathi kwezifo ezithathelwanayo ezibangelwa ukuqhuma okukhulu kwezingane nasezikhulile, okuyingozi kunazo zonke okulandelayo:
- ukutheleleka kwe-meningococcal okubhekene nokuqhuma okuqinile kwe-stellate, phakathi nendawo okungase kube khona izimpawu zokufa kwezicubu. Ukushona okubuhlungu ebusweni kungaba uphawu oluphawulekayo lwezinkinga ezinkulu zesifo, ezisongela impilo yesiguli;
- umfutho obomvu, obhekene nokubonakala kwe-hemorrhages lapho ufihla isikhumba;
- Ama-tick of ticks angabangela ukushisa komzimba, okuhambisana ne-rashes enkulu.
Lapho kuqhuma ukushisa okukhulu, kufanele uthintane nodokotela ngokushesha bese unciphisa ukuhamba kwakho ekuxilongweni nasekufakeni izibhedlela. Ezimweni eziningi, amahora okuqala ngemva kokuqala kokuphuthuma, usizo lokuqala luyadingeka, ngakho-ke asikho isikhathi sokuzama ukuzitholela. Uma kukhona ukuqhuma okukhulu kwezingane, kubalulekile ukugcina ukunakekelwa okukhethekile, ngisho nempilo evamile kubalulekile ukuhambisana nokuphumula kombhede ngaphambi kokufika kukadokotela.
