An allergen is something that the body does not recognize, and as a result produces antibodies to them. When this happens, an immune reaction takes place, giving you symptoms such as a runny nose, rash, etc.
An allergy is the reaction that the body will have, where as an allergen is something that causes the allergy to occur.
Your body responds with antibodies
histamine
it is sickness
Allergies can sometimes cause a fever in the body due to the immune system's response to an allergen. When the body detects an allergen, it releases chemicals that can lead to inflammation and an increase in body temperature, resulting in a fever. This reaction is part of the body's defense mechanism against the perceived threat of the allergen.
Fully hydrogenated soy oil is not considered an allergen, and is typically safe for those with food allergies. Overall, however, it is not a healthy food choice.
allergen
Allergies can sometimes trigger a fever as the body's immune system reacts to the allergen. When the immune system detects an allergen, it releases chemicals that can cause inflammation and raise body temperature, leading to a fever.
Your body doesn't "attack allergies". When you are exposed to something that sets off your allergies, your body is attacking a protein that is called an "allergen". This allergen can be anything, from pollen or ragweed to dust mites or the scent of a perfume. When you are exposed to the allergen, your body's immune system reacts against it as if it were an invading bacteria, setting up an inflammatory response. This is why you get the itchy watery eyes, runny nose, sneezing, dry throat reaction - it's your body's immune reaction.
The food allergy is a more general statement. If I say I'm allergic to peanuts I am not allergic to every aspect of the peanut only the "allergen" i.e. the specific protein that my body is reacting to. In theory if I was able to remove that protein or allergen I would be able to eat the peanut
When an allergen enters the body, the immune system recognizes it as a threat and produces antibodies to attack it. This triggers the release of chemicals like histamine, causing allergic symptoms such as sneezing, itching, hives, or in severe cases, anaphylaxis.
Yes, an allergy can cause a fever as part of the body's immune response to the allergen.
