Mae urticaria, a elwir hefyd yn hives, yn gyflwr ar y croen sy'n cael ei nodweddu gan ymddangosiad gwallt coch, sy'n chwistrellu, ac wedi'i chwistrellu ar y croen.
Gall gael ei achosi gan amrywiaeth o ffactorau, gan gynnwys adweithiau alergig, heintiau, a rhai meddyginiaethau.
Mae diagnosis urticaria yn cynnwys cyfuniad o hanes meddygol, archwiliad corfforol, ac weithiau profion labordy.
1. Hanes Feddygol: Bydd y meddyg yn gofyn am hanes meddygol y claf, gan gynnwys unrhyw alergeddau adnabyddus, clefydau diweddar, a meddyginiaethau a gymerwyd.
Byddant hefyd yn holi am ddechrau'r symptomau, eu cyfnod, a unrhyw sbardunoedd posibl.
2. Archwiliad corfforol: Bydd y meddyg yn archwilio'r croen ar gyfer presenoldeb welts, eu maint, a'u dosbarthiad.
Efallai y byddant hefyd yn gwirio am arwyddion eraill o adwaith alergig, fel chwyldro'r wyneb, y gwefusau, neu'r tafod.
3. profion labordy: Mewn rhai achosion, gall y meddyg orchymyn profion gwaed i wirio am fodolaeth alergeddau neu heintiau.
Gall profion croen, fel prawf chwistrellu croen neu brawf patch, hefyd gael eu cynnal i nodi alergenau penodol.
4. Profion alergedd: Os yw'r meddyg yn amau bod ymateb alergedd yn digwydd, gallan nhw gyfeirio'r claf at alergydd i gael profion pellach.
Gall hyn gynnwys profion chwistrellu croen, profion plastiau, neu brofion gwaed i nodi alergenau penodol.
5. Diagnosis gwahaniaethu: Bydd y meddyg hefyd yn ystyried achosion posibl eraill o'r symptomau, fel cyflyrau croen eraill neu gyflyrau meddygol sylfaenol, a gall orchymyn profion ychwanegol i wahardd y rhain.
6. Profion ysgogiad: Mewn achosion o urticaria corfforol, lle mae'r hives yn cael eu sbarduno gan ysgogiadau corfforol fel gwres, oer, neu bwysau, gall y meddyg wneud prawf ysgogiad i gadarnhau'r diagnosis.
Mae hyn yn cynnwys amlygu'r croen i'r sbardun amheus i weld a fydd adwaith yn digwydd.
7. profion autoimmune: Mewn achosion o urticaria cronig, gall y meddyg orchymyn profion i wirio am anhwylderau autoimmune, gan y gallant weithiau achosi'r cyflwr.
8. Profion delweddu: Mewn achosion prin, gellir gorchymyn profion delweddu fel X-ray neu CT scan i ddileu cyflyrau eraill a all achosi symptomau tebyg.
Yn gyffredinol, mae diagnosis urticaria yn cynnwys cyfuniad o hanes meddygol, archwiliad corfforol, ac weithiau profion labordy.
Y nod yw nodi'r achos sylfaenol a phenderfynu ar y cwrs triniaeth gorau ar gyfer y claf.

How is urticaria diagnosed?
Urticaria, also known as hives, is a skin condition characterized by the appearance of red, itchy, and swollen welts on the skin.
It can be caused by a variety of factors, including allergic reactions, infections, and certain medications.
Diagnosing urticaria involves a combination of medical history, physical examination, and sometimes laboratory tests.
1. Medical history: The doctor will ask about the patient's medical history, including any known allergies, recent illnesses, and medications taken.
They will also inquire about the onset of symptoms, their duration, and any potential triggers.
2. Physical examination: The doctor will examine the skin for the presence of welts, their size, and distribution.
They may also check for other signs of an allergic reaction, such as swelling of the face, lips, or tongue.
3. Laboratory tests: In some cases, the doctor may order blood tests to check for the presence of allergies or infections.
Skin tests, such as a skin prick test or patch test, may also be performed to identify specific allergens.
4. Allergy tests: If the doctor suspects an allergic reaction, they may refer the patient to an allergist for further testing.
This may include skin prick tests, patch tests, or blood tests to identify specific allergens.
5. Differential diagnosis: The doctor will also consider other possible causes of the symptoms, such as other skin conditions or underlying medical conditions, and may order additional tests to rule these out.
6. Provocation tests: In cases of physical urticaria, where the hives are triggered by physical stimuli such as heat, cold, or pressure, the doctor may perform a provocation test to confirm the diagnosis.
This involves exposing the skin to the suspected trigger to see if a reaction occurs.
7. Autoimmune tests: In cases of chronic urticaria, the doctor may order tests to check for autoimmune disorders, as these can sometimes cause the condition.
8. Imaging tests: In rare cases, imaging tests such as an X-ray or CT scan may be ordered to rule out other conditions that may cause similar symptoms.
Overall, diagnosing urticaria involves a combination of medical history, physical examination, and sometimes laboratory tests.
The goal is to identify the underlying cause and determine the best course of treatment for the patient.
