what is an ige allergy?

The immune system functions like a sentinel standing guard against foreign invaders.

In the case of an allergy, the invaders are called allergens. The primary weapon that it uses against invaders is the production of antibodies. The antibodies cause reactions that result in the offending allergens being removed from the body. In many people, foods act as allergens rather than nutrition. This can result in the symptoms of IBS.

The immune system produces numerous kinds of antibodies, called immunoglobulins. IgE and IgG are acronyms for the two different kinds of antibodies produced by the immune system in allergic reactions to food. You might be asking why you need to know this. Conventional allergy testing looks for IgE reactions only. These types of reactions typically occur immediately after contact with or ingestion of the allergen, and in some cases can cause serious, even fatal, health problems. Potential IgE reactions include swelling of the lips and tongue, hives, bloating, abdominal pain, or sudden diarrhea. These are the reactions that people usually think of when they hear the word allergy.
