Causes
When you are allergic to a substance, your body releases histamine and other chemicals into the blood. This causes itching, swelling, and other symptoms. Hives are a common reaction.

- Antihistamines are the first-line treatment for hives, as they block histamine, a chemical responsible for allergic reactions.
- Steroids: For severe cases, doctors may prescribe corticosteroids to reduce inflammation and swelling.

You might also be affected by hives during periods of extreme stress.
How common are hives
- Hives are a very common condition. About 20 percent of people have hives at some time during their lives. Hives develop when there is a reaction that activates immune cells in the skin called mast cells.
