Do you experience unexplained symptoms after eating certain foods? You're not alone. Food allergy symptoms affect millions of Americans, yet many people struggle for years without a proper diagnosis. Understanding the signs of food allergies can be life-changing – and potentially life-saving.
​
Food allergies occur when your immune system mistakenly identifies a harmless food protein as a threat, triggering a range of symptoms that can affect multiple body systems. From mild discomfort to severe, life-threatening reactions, food allergy reactions vary significantly in severity and presentation.

Immediate food allergy symptoms typically appear within minutes to two hours after consuming the trigger food.
​These reactions involve immunoglobulin E (IgE) antibodies and can range from mild to severe.

Before diving into testing options, it's important to understand the difference between food allergies and food sensitivities. Food allergies involve an immune system response that can range from mild hives to life-threatening anaphylaxis. Food sensitivities, while less severe, can still significantly impact your quality of life with symptoms like bloating, headaches, fatigue, and digestive issues.
Common food allergens include milk, eggs, peanuts, tree nuts, fish, shellfish, wheat, and soy – accounting for about 90% of all food allergic reactions. However, any food has the potential to trigger an allergic or sensitivity response.

Skin Prick Testing
The gold standard for food allergy testing, skin prick tests provide rapid results in about 15-20 minutes. During this test, small amounts of suspected allergens are introduced to the skin through tiny pricks. If you're allergic, a small raised bump will appear at the test site. This method is highly accurate for immediate allergic reactions and can test for multiple allergens simultaneously.

Blood Testing (Specific IgE)
For patients who cannot undergo skin testing due to severe eczema, certain medications, or other factors, blood tests measure specific IgE antibodies in your bloodstream. While results take longer than skin tests, blood testing can be particularly useful for detecting allergies to foods you haven't been exposed to recently.

Oral Food Challenge
Considered the most definitive test for food allergies, oral food challenges are conducted under strict medical supervision at our clinics. Patients consume increasing amounts of a suspected allergen while being closely monitored for reactions. This test is typically reserved for cases where other testing methods have been inconclusive.

Food Sensitivity Testing
Beyond traditional allergy testing, AFC Allergy & Med offers comprehensive food sensitivity panels that can identify delayed reactions to foods. These tests help uncover hidden triggers that might be causing chronic symptoms like digestive issues, skin problems, or fatigue.

Personalized Elimination Diets
Based on your test results, our specialists create customized elimination diets that remove problematic foods while ensuring proper nutrition. We provide detailed guidance on reading food labels, finding safe alternatives, and maintaining a balanced diet.

Oral Immunotherapy (OIT)
For select patients with food allergies, we offer oral immunotherapy – a groundbreaking treatment that gradually introduces tiny amounts of allergens to build tolerance over time. This treatment has shown remarkable success in reducing the severity of allergic reactions and improving quality of life.

Emergency Action Plans
Every patient receives a personalized emergency action plan detailing how to recognize and respond to allergic reactions. We ensure you and your family members understand proper use of epinephrine auto-injectors and when to seek emergency medical care.

Nutritional Counseling
​Managing food allergies often requires significant dietary changes. Our registered dietitians work with patients to develop meal plans that avoid trigger foods while maintaining optimal nutrition, especially important for growing children and adults with multiple food allergies.

Desert Expertise
