Urticaria: Understanding Hives and How to Manage Them
Urticaria, commonly known as hives, is a skin condition characterized by red, itchy welts that can appear anywhere on the body. While often harmless, it can cause discomfort and, in some cases, signal an underlying health issue.
What Is Urticaria?
Urticaria occurs when certain triggers cause the release of histamine and other chemicals in the skin, leading to swelling of the superficial layers. The result is raised, red or skin-colored welts that are often itchy and sometimes painful.
Urticaria can be:
Acute: Lasting less than six weeks. Often triggered by allergies, infections, or medications.
Chronic: Persisting for six weeks or longer, sometimes recurring for months or years, often without a clearly identifiable cause.
