Food Allergy

Food Allergies

If you have ever experienced red, itchy skin, swelling, vomiting or trouble breathing after eating or coming into contact with a certain food, you may wonder if you have a food allergy. Eight kinds of food cause most food allergies:

  • Cow's milk
  • Eggs
  • Peanuts
  • Wheat
  • Soy
  • Fish
  • Shellfish
  • Tree Nuts

While diagnosing food allergies can be tricky, an allergist has the training and expertise to know which tests to give you and how to accurately interpret them.

Food Challenge Testing

Your allergist will take a thorough medical history, followed by a physical exam. You may be asked about contents of the foods, the frequency, severity and nature of your symptoms and the amount of time between eating a food and any reaction.

An allergy skin test may determine which foods, if any, trigger your allergic symptoms. In skin testing, a small amount of extract made from the food is placed on your back or arm. If a raised bump or small hive develops within 20 minutes, it indicates a possible allergy.

To confirm your diagnosis, an allergist may perform a food challenge. Food challenges are done by consuming the food in a medical setting to determine if that food causes a reaction. Do not try this test at home. Anaphylaxis (pronounced an-a-fi-LAK-sis) is a serious allergic reaction that happens very quickly.

Once you know which foods you are allergic to, your allergist can help you develop a treatment plan so you can be healthy and safe.
