What causes Urticaria?

Cad a chuireann urticaria i bhfeidhm?

Is riocht craiceann é urticaria, ar a dtugtar hives freisin, a bhfuil bruite nó buamaí dearga, itchy, ardaithe air.

D'fhéadfadh fachtóirí éagsúla a bheith ina chúis leis, lena n-áirítear:

1. Freagairtí ailléirgeacha: Is féidir le freagairt ailléirgeach do bhia, le cógais, le stings feithidí, nó le allergens eile a spreagadh urticaria.

2. Fachtóirí fisiceacha: Is féidir le nochtadh le teas, fuar, solas na gréine, nó brú ar an gcraiceann hives a chur faoi deara i roinnt daoine.

3. Infections: Is féidir le ionfhabhtuithe víreasacha, mar shampla an fuar coitianta nó an fliú, urticaria a spreagadh uaireanta.

4. neamhoird autoimmune: I gcásanna áirithe, d'fhéadfadh neamhoird autoimmune a bheith ina chúis le urticaria, nuair a ionsaíonn córas imdhíonachta an chomhlachta fíochán sláintiúil go mícheart.

5. Fachtóirí géiniteacha: D'fhéadfadh go mbeadh claonadh géiniteacha ag roinnt daoine urticaria a fhorbairt.

6. Leigheasra: Is féidir le cógais áirithe, mar shampla aspirin, penicillin, nó drugaí frith-athlastacha neamhstéaróideacha (NSAIDs), urticaria a chur faoi deara i roinnt daoine.

7. Breoiteachtaí ainsealacha: Uaireanta d'fhéadfadh coinníollacha leighis bunúsach, mar shampla galar thyroid nó ailse, urticaria a bheith ina chúis.

8. Strus: Is féidir le strus mothúchánach urticaria a spreagadh uaireanta i ndaoine atá leochaileach.

Tá sé tábhachtach a thabhairt faoi deara nach féidir an chúis cruinn le urticaria a shainaithint i go leor cásanna.

Mar sin féin, is féidir le fachtóirí féideartha a shainaithint agus a sheachaint cabhrú le comharthaí a chosc nó a laghdú.

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.

However, identifying and avoiding potential triggers can help prevent or reduce the severity of symptoms.
