FOOD ALLERGY TESTING SPECIALISTS

Our relationship with food is a complicated one. We often love food, but it doesn’t always love us back. Adverse reactions to foods are a common experience for many people. There are many reasons why someone may be experiencing a bad reaction to a specific food and our experienced providers will help navigate this complicated relationship. Read below for more information on common food-related conditions.

Common food allergies tested and managed at the Arizona Asthma and Allergy Institute:

1. Food Allergy/Anaphylaxis

A serious life-threatening allergic reaction which usually occurs within few seconds or minutes of consuming certain foods. Symptoms may include abdominal pain, diarrhea, hives, itching, throat swelling, difficulty breathing, and loss of consciousness. If not treated appropriately this condition can be life threatening.

2. Oral Allergy Syndrome

Patients typically present with swelling and itching of the mouth and throat after eating certain vegetables and fresh fruits like melons. This is thought to be due a cross-reactivity between common plant pollens and the proteins found in these foods. Symptoms are due to a manifestation of environmental allergies rather than an allergy to the food itself.

3. Eosinophilic Esophagitis (EoE)

Localized inflammation and swelling of the esophagus due to the consumption of certain foods. Unlike a classic food allergy/anaphylaxis symptoms are often less dramatic and progress over time. The most common symptoms are failure to thrive in early childhood and difficulty swallowing in older children and adults.

4. Celiac Disease

An immune disorder triggered by gluten (a component of wheat and related cereals) in genetically predisposed individuals. This condition may result in malabsorption presenting as chronic diarrhea, failure to thrive, rash, and arthritis. Of note, this is a different condition than wheat allergy.
