Food Allergies Q & A

What are food allergies?

Food allergies are a serious medical condition. If you have a food allergy, your body’s immune system overreacts to certain foods.

While you can be allergic to any kind of food, the most common foods that trigger an allergic reaction are:

  • Peanut
  • Soy
  • Fish
  • Milk
  • Eggs
  • Wheat
  • Tree nuts

Those who have food allergies are more likely to have other allergy-related conditions like eczema and asthma. Your risk for having food allergies increases if other members of your family have them.

What are the symptoms of food allergies?

Food allergy symptoms range from mild to life-threatening. When you eat/ingest a trigger food, it can cause:

  • Hives
  • Dizziness
  • Mouth tingling
  • Facial swelling

People who suffer anaphylaxis, a life-threatening allergic reaction, develop breathing difficulties because of sudden inflammation in the throat or lungs. If you experience symptoms of anaphylaxis, call 911 or get to a hospital emergency room right away to prevent life-threatening complications, including death.

How are food allergies diagnosed?

Apex Allergy and Asthma provides on-site allergy tests and blood work to determine if your symptoms are caused by food allergies or another medical condition.

During an allergy test, the providers prick your skin with a small amount of a known allergen. If you have an allergy to that specific substance, a red welt forms on your skin. They usually test your reaction to more than one allergen at a time. The providers also use blood tests to evaluate how your immune system responds to certain foods.

You might need to cut out certain foods from your diet for a time and then slowly add them back to identify the causes of your allergies.

How are food allergies treated?

If you suffer mild reactions from a food allergy, you might benefit from over-the-counter antihistamines. The Apex Allergy and Asthma providers can also help you avoid the foods that cause your allergic reactions.

If you have a severe reaction to foods, you’ll need an epinephrine injection to quickly reduce the inflammation in your throat. You must go immediately to the nearest emergency room or call 911 following a severe food allergy reaction.

The allergy specialists at Apex Allergy and Asthma will help you plan for such emergencies. When you have anaphylaxis, you must carry an epinephrine injector pen (such as an EpiPen®) with you at all times and always be aware of what you’re eating.
