Is allergy and chronic urticaria the same thing?

Urticaria is an allergic disease. Urticaria is the diagnosis result and allergy is the cause. There is no comparability between them. Urticaria, commonly known as rash, is a transient wheal on the skin caused by various allergic reasons, accompanied by itching. The wind mass can subside within 24 hours, but new skin lesions appear one after another, leaving no trace. The pathological change of urticaria is transient edema in the superficial dermis.

Urticaria is mostly caused by allergic reasons, especially chronic urticaria, and the reasons are complicated. The common causes of allergies are drugs, food, breathing, toxins, physical factors, cold and heat, wind, sun exposure, mental factors or immune diseases. These will all lead to skin allergies, manifested as urticaria. Patients with urticaria first have itchy skin, and then quickly appear red or pale white wheal, which can disappear within 24 hours without leaving traces. Urticaria can involve respiratory mucosa and digestive tract mucosa, causing corresponding clinical symptoms.

Patients with urticaria should first remove the allergic causes leading to urticaria. They can take antihistamines orally or in combination. Different types of urticaria use different antihistamines. For infectious urticaria, oral antibiotics can be used. If the patient is accompanied by clinical symptoms of respiratory tract, digestive tract and cardiovascular system, he should go to the hospital in time, be examined in detail by an emergency doctor or dermatologist, and be given correct treatment.
