Ukuphuhliswa kwamagciwane kunye nokuba kutheni ukuphendula kuhluka
Nantsi inyaniso elula malunga neengxaki zentlungu : awukwazi ukufumana isisombululo sokubangela into ongayange uhlangabezane nayo. Oku kungenxa yokuba umzimba awuyi kuqonda into njengotyikwano de kube emva kokuhlangana ezininzi.
Ngokungafani nentsholongwane okanye iibhaktheriya, ezininzi izifo aziyi kubangela impendulo yangasese kwi-immune system. Kunoko, impendulo eqhubeka ngokuhamba kwexesha, kaninzi ingenakho isigqi okanye isizathu sokuba kutheni kwabanye abantu kungekhona kwabanye.
Inkqubo eyenziwa ngumzimba wakho-kwaye inkunkuma ethile-into ethile ichazwa ngokuba yi-sensitization.
Ukuqonda ukuSenisisation kunye ne-Allergies yangempela
Ukwazisa inkqubo yenkqubo apho umzimba wokuzivikela oza kuvelisa iprotheni ekhuselayo, ebizwa ngokuba ngumntu olwaphilileyo , ekuphenduleni nayiphi na into ebona ingaqhelekanga, kuquka ukutya okunye, ipollen, isikhunta okanye imithi.
Ukuveliswa kwe-antibody, nangona kunjalo, akuyikhokelela kwiimpawu. Ngokuxhomekeke kumntu, impendulo inokuvela kwizinto ezincinci okanye ezingekho kwizinto ezinzulu kunye nokuba zisongela ubomi.
Ngaloo ndlela, "ukunyaniseka kweqiniso" yindlela eyenzekayo yenziwa ngumzimba wokhuseleko lomzimba ekuphenduleni i-agent-causing causing agent (allergen). Ukuba kukho iziganeko zengqungquthela kodwa akukho mpendulo ephawulekayo, sibhekisela kuloo nto njengobuninzi bokuqonda.
Iimpawu zokungabikho komzimba zingabandakanya:
- Ukugqithisa isikhumba
- Iimbuzi
- Ukutshekisha amehlo okanye ulusu
- Ukugubha
- I-Rhinitis (ukuxhamla emanzini, ukukrazula, ukudibanisa)
Kwiimeko ezinzima kakhulu zokungabonakali-njengento yokuluma kwezinambuzane , isilwanyana ( njengepenicillin ), okanye ukutya (njengamanqatha) -ahlobo olunzulu lokungabikho komzimba lungakhula ngokubizwa ngokuba yi-anaphylaxis. Lo mzimba wonke uphendule ukuphazamiseka kweempawu kwaye ubangele ukuphefumula, ukuphazamiseka , kunye nokufa.
Utshintsho kwi-Sensitivevity Allergic
Okuthakazelisayo ngokwaneleyo, ukuvalelwa komzwelo kungabi nje kuphela okuhlukileyo ngumntu kodwa ngelo lizwe ohlala kulo. Ngokomzekelo, ukuba uhlala kwingxenyeni esezantsi ye-US, unakho amathuba okuba unobungozi beeqanda, ubisi, i-shrimp , kunye namanqatha. Ukuba uhlala eItali, ukhululekile ukuba uhlaselwe kwiintlanzi.
Nangona izazinzulu aziqinisekanga ngokupheleleyo ukuba kutheni le nto yenzeka, abanye bakholelwa ukuba ukusetyenziswa kokutya okuthe ngqo kwindawo ethile kuya kuguqulela kwisiganeko esiphezulu se-allergies ethile.
Ngakolunye uhlangothi, indlela yokutya ethile iqhutywe ngayo (okanye nokuba umhlaba ukhula) unokuba negalelo kwimeko. Kuyafana nokungcola okanye i-toxins ezixhaphakileyo kwiindawo ezithile zehlabathi kwaye ngaphantsi kwezinye.
Ekugqibeleni, konke kubuyiselwa kwinqanaba lethu eliphambili: awukwazi ukufumana into engafanelekanga kuyo.
Ubuninzi bokusebenza
Ukuba umntu unobungozi obuyinyaniso, ubukho be-antibody echasayo buya kuhlala bukhona kwigazi. Ngaloo ndlela, naphi na umntu echazwe kwi-allergen, i-antibody iya kuba khona ukuqala impendulo.
Nangona kunjalo, kwezinye iimeko, i-immune system iya kuphazamisa i-allergengen ye-allergen yangempela.
Oku kubizwa ngokuba yi-cross-reactivity kwaye kwenzeka xa iprotheni ye-allergen njenge-pollen ifana nesakhiwo sesinye into, njengesityalo.
Siyibona le nto ihlala rhoqo kunye nemeko eyaziwa njenge- oral allergies syndrome (i-OAS), impendulo engapheliyo phakathi kwepollen kunye nezinye iziqhamo eziluhlaza. Njengoko ubukhulu bokuqala buvela kwimpova, iimpawu zokungahambi kakuhle kwesiqhamo zivame ukuba ziqine kwaye ziphoswe apho iziqhamo zidibene nomlomo okanye ngomlomo.
Kule nkalo, i-OAS ayilona yinto engamkelekanga kodwa yinto efanelekileyo "yesazisi ephosakeleyo" kwinqanaba le-immune system.
