What causes urticaria?

Urticaria, also known as hives, is a skin condition characterized by red, itchy, raised welts or bumps.

It can be caused by a variety of factors, including:

1. Allergic reactions: Urticaria can be triggered by an allergic reaction to food, medications, insect stings, or other allergens.

2. Physical factors: Exposure to heat, cold, sunlight, or pressure on the skin can cause hives in some people.

3. Infections: Viral infections, such as the common cold or flu, can sometimes trigger urticaria.

4. Autoimmune disorders: In some cases, urticaria may be caused by an autoimmune disorder, where the body's immune system mistakenly attacks healthy tissue.

5. Genetic factors: Some people may have a genetic predisposition to developing urticaria.

6. Medications: Certain medications, such as aspirin, penicillin, or nonsteroidal anti-inflammatory drugs (NSAIDs), can cause urticaria in some individuals.

7. Chronic illnesses: Underlying medical conditions, such as thyroid disease or cancer, can sometimes cause urticaria.

8. Stress: Emotional stress can sometimes trigger urticaria in susceptible individuals.

It is important to note that in many cases, the exact cause of urticaria may not be identified.

However, identifying and avoiding potential triggers can help prevent or reduce the severity of symptoms.
