Food Allergies

What is food allergy?

A food allergy is an abnormal response of the body to a certain food. It is important to know that this is different than a food intolerance, which does not affect the immune system, although some of the same signs may be present.

What causes food allergy?

Before having a food allergy reaction, a sensitive person must be exposed to the food at least once before. It is the second time the person eats the food that the allergic symptoms happen. At that time, when IgE antibodies react with the food, histamines are released, which can cause hives, asthma, itching in the mouth, trouble breathing, stomach pains, vomiting, or diarrhea.

Treatment for a food allergy in adults:

Specific treatment for a food allergy will be determined by your physician based on:

• your age, overall health, and medical history
• extent of the condition
• your tolerance for specific medications, procedures, or therapies
• expectations for the course of the condition
• your opinion or preference
