Why am I Breaking out in Hives?

When you break out in hives, it can be a little scary. The good news is that hives are usually not serious and will go away on their own. You just need to know why they’re happening, how to treat them, and what to do if they don’t go away.

You’re breaking out in hives, and it’s probably because you ate something. But why?

The answer is simple: The body has a natural defence system that helps protect us from viruses and bacteria.

Our immune system uses white blood cells to fight off disease, but when we eat something that’s made with a food allergen (think milk or soy), our bodies respond by releasing histamine into the bloodstream.

Histamine causes inflammation, which causes hives those itchy bumps that pop up on your skin.

So what should you do when you break out in hives?

First of all, try to figure out what caused it. It could be something as simple as eating too much sugar or caffeine, or drinking too much alcohol (either of which can cause an allergic reaction).

Or maybe it’s something more serious like an allergy to shellfish or nuts that requires treatment from a doctor so that you don’t make things worse by continuing to eat what gives you hives.

But if you think back to what you ate before the reaction started, there might be some clues about what caused it!

If nothing else, remember this: the next time your skin starts itching like crazy after eating something new

The most common causes of hives include allergies, infections, stress and exercise.


If you’ve recently tried a new food or have been exposed to something that bothers you, it could cause your body to react by causing hives.


An infection such as chickenpox or measles can also cause hives. These infections are contagious so if someone in your family has them they could spread them to you too!

Stress & Exercise:

Stress and exercise can both cause hives in some people. For some people, this happens because their bodies produce too much histamine when under stress or during intense workouts which can lead to an allergic reaction known as anaphylaxis.
