Chronic urticaria explained in first person
Professionals and patients explain how you live with the disease
It is difficult to explain because everyone believes it is an allergy. There is no miracle or cure other than properly treating the outbreaks.
Types of Chronic Urticaria
Urticaria is classified depending on the duration of the lesions:
Acute urticaria. If it lasts for less than six weeks.
Chronic urticaria. When the lesions last for six weeks or more and appear daily or almost daily.
Chronic urticarias can be classified as spontaneous, if there are no triggers, or inducible, if there are triggers (water, cold, pressure, friction, vibration, temperature increase or physical exercise).
Urticarias due to an allergic trigger (foods or medicines) require investigation by a specialist to confirm the cause and be able to avoid contact to prevent the reaction.
How many people are affected by Chronic Urticaria?
Urticaria affects people of all ages (children and adults), although it is more common in adults, especially in women, in its chronic form. Approximately 1 in 5 people in the world will exerience an episode of acute urticaria over their lives, while the chronic form of the disease has an estimated annual prevalence of approximately 1% of the population. It is estimated that there are more than 250,000 people in Spain with chronic urticaria.
