Is it trying to fix itself by closing the airways?….Or is it just a reaction and not a defense.

> Causes
The immune system produces antibodies that defend against foreign substances. This is good when a foreign substance is harmful, such as certain bacteria or viruses. But some people’s immune systems overreact to substances that don’t normally cause an allergic reaction.
>Allergy symptoms aren’t usually life-threatening, but a severe allergic reaction can lead to anaphylaxis. Even if you or your child has had only a mild anaphylactic reaction in the past, there’s a risk of more severe anaphylaxis after another exposure to the allergy-causing substance.
>The most common anaphylaxis triggers in children are food allergies, such as to peanuts and tree nuts, fish, shellfish, wheat, soy, sesame and milk. Besides allergy to peanuts, nuts, fish, sesame and shellfish, anaphylaxis triggers in adults include:
>Certain medications, including antibiotics, aspirin and other pain relievers available without a prescription, and the intravenous (IV) contrast used in some imaging tests
Stings from bees, yellow jackets, wasps, hornets and fire ants
Latex
Although not common, some people develop anaphylaxis from aerobic exercise, such as jogging, or even less intense physical activity, such as walking. Eating certain foods before exercise or exercising when the weather is hot, cold or humid also have been linked to anaphylaxis in some people. Talk with your health care provider about precautions to take when exercising.
>If you don’t know what triggers an allergy attack, certain tests can help identify the allergen. In some cases, the cause of anaphylaxis is not identified (idiopathic anaphylaxis).
Hope that helps.
Tl;dr: (as I understand it)— more or less, some people’s physiological response to infection or venom intake; for lack of a better explanation: “over reacting” from a viewing perspective of how one persons body reacts as opposed to another— while the body feels it’s necessary, it can kill you.
Im definitely not a doctor. I’d probably read the article to fill in any gaps, but I sort of paraphrased it in the tl;dr.
