Understanding Chronic Spontaneous Urticaria

Chronic spontaneous urticaria (CSU) is a persistent and often autoimmune skin condition characterized by hives that last for over six weeks, typically affecting individuals for three to five years. It manifests as itchy wheals and can accompany angioedema, which is deep swelling of the skin. Epidemiologically, about 1% of the general population is affected by CSU, with the likelihood of experiencing at least one episode significantly higher over a lifetime. The condition's prevalence is on the rise, and it can present with varied symptoms, making it essential to understand its classification as acute or chronic based on duration.
