Mae urticaria, a elwir hefyd yn hives, yn gyflwr croen cyffredin sy'n effeithio ar oddeutu 20% o'r boblogaeth gyffredinol ar ryw adeg yn eu bywydau.
Mae'r achosion o urticaria yn amrywio yn dibynnu ar oedran, rhywedd, a lleoliad daearyddol.
Mewn plant, amcangyfrifir bod yr achosion tua 1% y flwyddyn, tra mewn oedolion, mae tua 1-2% y flwyddyn.
Amcangyfrifir bod lledaeniad urticaria cronig mewn oedolion tua 0.5-1%. Fodd bynnag, gall y rhifau hyn amrywio oherwydd gwahaniaethau mewn dulliau astudiaeth a nodweddion y boblogaeth.
Mae'n bwysig nodi y gallai'r achosion a'r lledaeniad o urticaria gael eu tanamcangyfrif oherwydd llai o adroddiadau a anghywir diagnosis.

How common is urticaria?
Urticaria, also known as hives, is a common skin condition that affects approximately 20% of the general population at some point in their lives.
The incidence of urticaria varies depending on age, gender, and geographical location.
In children, the incidence is estimated to be around 1% per year, while in adults, it is approximately 1-2% per year.
The prevalence of chronic urticaria in adults is estimated to be around 0.5-1%. However, these numbers may vary due to differences in study methodologies and population characteristics.
It is important to note that the incidence and prevalence of urticaria may be underestimated due to underreporting and misdiagnosis.
