WebMD 1:01: How Do Allergies Work?

Allergies. They can have a big impact on your life.

Leah

Oh, I know. I once dated this amazing guy who had a cat. I'm allergic. So he had to decide between me and the cat.

NOAH

Which did he choose?

Leah

The cat, Noah. Donald picked the cat. OK? Now, let's learn about these allergies that ruined my life. Allergies happen when your immune system thinks a substance, like stupid pet dander, is a dangerous intruder.

NOAH

When a person with allergies is exposed to an allergen-- through food, insect bites, or even pollen-- the body produces a large quantity of antibodies.

Leah

Those antibodies then cause some cells to release chemicals into the bloodstream, one of which is histamine.

NOAH

The histamine then acts on the eyes, nose, throat, lungs, skin, or gastrointestinal tract, and causes the symptoms of an allergic reaction.

Leah

Stupid histamines.

NOAH

Hey, come on. They're only trying to help.

Leah

Whatever. Reactions can range from mild to severe, where emergency medical treatment is needed. But most of the time, some medication will do the trick.

NOAH

And people can be allergic to almost anything, from foods to medications to grass, ragweed, to animal dander, from dogs and cats-- Katz's Deli-- ca-- nondogs.

Leah

Cats. You can say it. Cats. I am over Donald and that dumb Mr. Snugglebottoms.

NOAH

Yeah. Clearly. [MUSIC PLAYING]
