Which condition is also known as hives?

The condition referred to as hives is commonly known as urticaria. Urticaria is characterized by raised, itchy welts on the skin that can vary in size and can appear anywhere on the body. This immune response often occurs due to an allergic reaction, but it can also be triggered by other factors such as stress, temperature changes, or certain medications.

The name "hives" is frequently used in clinical settings and among patients to describe the sudden outbreaks of these itchy welts, which can have varying durations, from hours to days. Understanding urticaria is important for diagnosis and management, especially in terms of identifying triggers and possible treatment options that may include antihistamines or other medications to relieve symptoms.

In contrast, angioedema refers to swelling in deeper layers of the skin, typically around the eyes and lips, and may accompany urticaria but is distinct from it. Dermatitis is a general term for skin inflammation and can encompass various conditions that may not be related to hives. Psoriasis is a chronic condition characterized by thick, red, scaly patches on the skin, which is also unrelated to hives. Recognizing urticaria as the medical term for hives is crucial for proper communication and treatment
