Food Allergies and Sensitivities Testing

Identifying the Foods That May Be Harming Your Health

Food allergies and sensitivities are far more common than many people realize and can be a hidden driver of a wide range of chronic health problems. At Dr. Jeri Lynn Otterstrom’s practice in Eugene, OR, we offer comprehensive testing and evaluation for food allergies and sensitivities to help patients identify the dietary triggers contributing to their symptoms and develop a path toward relief.

While true food allergies involve an immediate IgE-mediated immune response that is often dramatic and easily recognized, food sensitivities are more subtle and delayed. IgG-mediated reactions and other sensitivity mechanisms can produce symptoms that appear hours or even days after consuming a reactive food, making them extremely difficult to identify without proper testing.

Food sensitivities have been linked to a broad spectrum of health concerns including chronic digestive issues, irritable bowel syndrome, bloating and gas, skin conditions such as eczema and psoriasis, migraines, joint pain, brain fog, fatigue, mood disturbances, and autoimmune flares. Many patients who have struggled with these conditions for years find significant relief once reactive foods are identified and removed.

At Dr. Otterstrom’s practice, food sensitivity testing uses advanced immunological assays to identify reactive foods across a comprehensive panel. Testing evaluates immune responses to a wide range of commonly consumed foods, giving patients and their provider clear, actionable information about which foods are contributing to inflammation and symptoms.

Testing results are reviewed in detail during a dedicated consultation. Dr. Otterstrom works with each patient to develop a practical elimination and reintroduction protocol that removes reactive foods, supports gut healing, and gradually reintroduces foods in a systematic way to determine which can eventually be tolerated again.

Food sensitivity work is often combined with gut health support, as intestinal permeability — commonly known as leaky gut — is frequently both a cause and consequence of food reactivity. Healing the gut lining reduces immune reactivity and helps restore a broader, healthier relationship with food over time.

We recognize that dietary changes can be challenging, and we provide practical guidance, meal planning support, and resources to help patients navigate their elimination protocol successfully without feeling deprived or overwhelmed.

If you suspect that food sensitivities may be contributing to your health challenges in Eugene, OR, Dr. Jeri Lynn Otterstrom offers comprehensive food allergy and sensitivity testing designed to help you identify your triggers and take meaningful steps toward feeling better.
