The first time a person is exposed to an allergen, they do not usually experience a reaction. It often takes time for the immune system to build up a sensitivity to the substance.

As it does so, it starts making antibodies to attack it when exposure occurs. This buildup is called sensitization.

Anaphylaxis can develop quickly, with symptoms appearing within minutes or hours of exposure to the allergen. Research suggests that anaphylaxis most commonly affects the skin and respiratory system. Learn more about the symptoms of anaphylactic shock here.

When an allergic reaction occurs, allergens bind to antibodies that the body produces called immunoglobin E IgE. Antibodies combat foreign and potentially harmful substances in the body. Once the allergen binds to IgE, specific types of cells — including mast cells — will release chemicals that trigger the symptoms of the allergic reaction.

Histamine is one of these chemicals. It causes the muscles in the airways and walls of the blood vessels to tighten. The severity of allergies varies from person to person and can range from minor irritation to anaphylaxis — a potentially life-threatening emergency.

A severe allergic reaction, which can be triggered by foods or venom insect stings , is called anaphylaxis. This is a life-threatening emergency condition in which the patient goes into shock, cannot breathe, and may have vomiting, nausea, and skin rashes. Anaphylaxis can occur instantaneously or sometimes minutes after eating an allergen or being stung.

That said, they had fewer instances of shellfish allergies specifically. Why does this happen? The verdict is still out. Medical and scientific researchers alike are still working on figuring out why adults have a higher likelihood of getting a shellfish allergy compared to children. One purported reason could be that the allergy is always present, just sitting dormant, like we mentioned above. Unfortunately, you cannot prevent the manifestation of adult-onset allergies.

As we mentioned, these allergies sometimes spring up where none existed before. Other times, exposure to the allergen triggers a reaction. If, for instance, you notice you get an adverse reaction after eating shellfish or peanuts, you should refrain from eating these foods right away.
