How Are Hives Formed?

Hives are formed when your immune system reacts to something in your body or the environment. The immune system produces a substance called histamine, which causes blood vessels to expand so that more blood can flow through them. This is why hives are red and raised, as they appear when the blood vessels beneath the skin expand.

The most common cause of hives is an allergic reaction to an insect bite or stinging insect, medication, food, or other substance that triggers an immune response. Hives can also be caused by certain infections, including strep throat and hepatitis; certain types of cancer; autoimmune diseases such as lupus, rheumatoid arthritis, and multiple sclerosis; pregnancy; physical trauma to the skin; stress; exercise; heat exposure; and cold exposure (such as swimming).

Hives are usually harmless unless they become severe enough to cause difficulty breathing or swallowing. In these cases, you should seek medical attention immediately.
