Glossary Chronic Urticaria

persistent itchy hives lasting over six weeks without clear cause

Chronic Urticaria, also known as Chronic Hives or Chronic Idiopathic Urticaria (CIU), is a condition characterized by the presence of hives or wheals on the skin that persist for six weeks or longer. These itchy, red welts can appear anywhere on the body and may be triggered by various factors, including stress, certain foods, medications, or underlying health conditions. The exact cause is often unknown, making it idiopathic, and it can significantly impact a person's quality of life.
