7 Best Doctors for Hives available in Patna

Hives, also known as urticaria, are the result of an allergic reaction causing an abnormal immune response to any foreign substance.

Hives appear as a red, itchy, and raised rash. They may appear in various sizes, ranging from a pea-sized rash to large blotches. They tend to repeatedly fade and reappear depending on the severity of the allergy.

Increased levels of histamines in the body cause hives. Irritants that increase these levels are:
-Pollen
-Food
-Insect bites and sting
-Sunlight
- Chemicals
- Emotional stress
- Shellfish, eggs, and nuts

A dermatologist will review the person’s history to identify the cause of hives. Further, he will inspect the skin. An allergic skin test or skin biopsy may also be conducted to diagnose the cause of allergy.

Hives can sometimes be life-threatening due to a severe allergic response called anaphylaxis, which constricts the airways and causes difficulty in breathing. This needs immediate medical attention.
