Yini ebangela i-urticaria?

I-urticaria, eyaziwa nangokuthi i-hives, iyisimo sesikhumba esibonakala ngokubomvu, ukulunywa, ama-welts aphakanyisiwe noma ama-bumps.

Kungase kubangelwe izici ezihlukahlukene, kuhlanganise:

1. Ukusabela kwe-allergic: I-urticaria ingabangelwa ukusabela kwe-allergic kokudla, imithi, ukulunywa izinambuzane, noma ezinye izinto ezibangela ukungezwani komzimba.

2. Izici zomzimba: Ukuchayeka ekushiseni, emakhazeni, ekukhanyeni kwelanga, noma ekucindezelweni kwesikhumba kungabangela izinduna kwabanye abantu.

3. Ukutheleleka: Ukutheleleka ngegciwane, njengomkhuhlane ovamile noma umkhuhlane, ngezinye izikhathi kungabangela i-urticaria.

4. Ukuphazamiseka kwe-autoimmune: Kwezinye izimo, i-urticaria ingase ibangelwe ukuphazamiseka kwe-autoimmune, lapho isimiso somzimba sokuzivikela komzimba sihlasela khona izicubu ezinempilo ngephutha.

5. Izici zofuzo: Abanye abantu bangase babe nokuthambekela kwezakhi zofuzo ekuthuthukiseni i-urticaria.

6. Imithi: Imithi ethile, njenge-aspirin, i-penicillin, noma imithi elwa nokuvuvukala engeyona i-steroidal (i-NSAIDs), ingabangela i-urticaria kwabanye abantu.

7. Izifo ezingamahlalakhona: Ngezinye izikhathi izifo eziyisisekelo, njengezifo ze-thyroid noma umdlavuza, zingabangela i-urticaria.

8. Ukucindezeleka: Ukucindezeleka okungokomzwelo ngezinye izikhathi kungabangela i-urticaria kubantu abathambekele kuyo.

Kubalulekile ukuphawula ukuthi ezimweni eziningi, imbangela eqondile ye-urticaria ingase ingatholakali.

Nokho, ukukhomba nokugwema izimbangela ezingaba khona kungasiza ekuvimbeleni noma ekunciphiseni ubunzima bezimpawu.

Ukuzikhulula: kwezokwelapha

Le webhusayithi inikezwa ngezinjongo zemfundo nezokwaziswa kuphela futhi ayifaki ukunikeza izeluleko zezokwelapha noma izinsizakalo zobungcweti.

Imininingwane enikeziwe akufanele isetshenziselwe ukuxilonga noma ukwelapha inkinga noma isifo, futhi labo abafuna iseluleko somuntu siqu sezokwelapha kufanele babonane nodokotela onelayisense.

Sicela uqaphele ukuthi inethiwekhi ye-neural ekhiqiza izimpendulo zemibuzo, ayinembile ngokukhethekile uma kuziwa kokuqukethwe kwezinombolo. Ngokwesibonelo, inani labantu abanesifo esithile.

Ngaso sonke isikhathi funa iseluleko sikadokotela wakho noma omunye umhlinzeki wezempilo ofanelekayo mayelana nesimo sezokwelapha. Ungalokothi ungayinaki iseluleko sezokwelapha sobungcweti noma ubambezele ukusifuna ngenxa yento oyifundile kule webhusayithi. Uma ucabanga ukuthi ungase ube nesimo esiphuthumayo sezokwelapha, shayela i-911 noma uye egumbini lezimo eziphuthumayo eliseduze ngokushesha. Ayikho ubudlelwano bokuthi udokotela-isiguli obakhiwe yile webhusayithi noma ukusetshenziswa kwayo. I-BioMedLib noma abasebenzi bayo, noma noma yimuphi umnikeli wale webhusayithi, akenzi noma yimiphi imibono, ecacile noma ecacile, mayelana nolwazi olunikezwe lapha noma ukusetshenziswa kwayo.

Ukuzikhulula: amalungelo obunikazi

I-Digital Millennium Copyright Act ka-1998, i-17 U.S.C. § 512 (i- DMCA) inikeza indlela yokuphendula kubanikazi bamalungelo obunikazi abakholelwa ukuthi okokusebenza okubonakala kwi-Internet kwephula amalungelo abo ngaphansi komthetho we-copyright wase-US.

Uma ukholelwa ngobuqotho ukuthi noma yikuphi okuqukethwe noma okokusebenza okwenziwe kutholakale maqondana newebhusayithi yethu noma izinsizakalo kwephula ilungelo lakho lobunikazi, wena (noma umenzeli wakho) ungasithumela isaziso esicela ukuthi okuqukethwe noma okokusebenza kususwe, noma ukufinyelela kukho kuvinjelwe.

Izaziso kufanele zithunyelwe ngokubhala nge-imeyili (bheka isigaba esithi "Contact" ukuze uthole ikheli le-imeyili).

I-DMCA idinga ukuthi isaziso sakho sokwephulwa kwamalungelo obunikazi kubandakanye imininingwane elandelayo: (1) incazelo yomsebenzi onamalungelo obunikazi oyisihloko sokwephulwa okusolwa; (2) incazelo yokuqukethwe okusolwa ukwephula amalungelo obunikazi nolwazi olwanele ukusivumela ukuthi sithole okuqukethwe; (3) imininingwane yokuxhumana nawe, kufaka phakathi ikheli lakho, inombolo yocingo nekheli le-imeyili; (4) isitatimende sakho sokuthi unokholo oluhle lokuthi okuqukethwe ngendlela ekhonjiwe ngayo akugunyaziwe ngumnikazi wamalungelo obunikazi, noma umenzeli wakhe, noma ngokusebenza kwanoma imuphi umthetho;

(5) isitatimende sakho, esisayinwe ngaphansi kwesijeziso sokufakaza amanga, sokuthi ukwaziswa okusesazisweni kunembile nokuthi unegunya lokuphoqelela amalungelo obunikazi okuthiwa aphuliwe;

futhi (6) isignesha ebonakalayo noma ye-elekthronikhi yomnikazi we-copyright noma umuntu ogunyaziwe ukuba asebenze egameni lomnikazi we-copyright.

Ukwehluleka ukufaka yonke imininingwane engenhla kungaholela ekubambezelweni kokucutshungulwa kwesikhalazo sakho.

What causes urticaria?

Urticaria, also known as hives, is a skin condition characterized by red, itchy, raised welts or bumps.

It can be caused by a variety of factors, including:

1. Allergic reactions: Urticaria can be triggered by an allergic reaction to food, medications, insect stings, or other allergens.

2. Physical factors: Exposure to heat, cold, sunlight, or pressure on the skin can cause hives in some people.

3. Infections: Viral infections, such as the common cold or flu, can sometimes trigger urticaria.

4. Autoimmune disorders: In some cases, urticaria may be caused by an autoimmune disorder, where the body's immune system mistakenly attacks healthy tissue.

5. Genetic factors: Some people may have a genetic predisposition to developing urticaria.

6. Medications: Certain medications, such as aspirin, penicillin, or nonsteroidal anti-inflammatory drugs (NSAIDs), can cause urticaria in some individuals.

7. Chronic illnesses: Underlying medical conditions, such as thyroid disease or cancer, can sometimes cause urticaria.

8. Stress: Emotional stress can sometimes trigger urticaria in susceptible individuals.

It is important to note that in many cases, the exact cause of urticaria may not be identified.
