Diagnosis and testing

These questions help families understand what food allergy is, how it is diagnosed, and why specialist evaluation matters.

Q1. What is a food allergy?

A food allergy happens when the immune system reacts to a food protein as though it were harmful.

A food allergy involves the immune system, while an intolerance usually does not.

Diagnosis may include symptom history, examination, skin testing, blood testing, and in some cases additional specialist evaluation.

Not always. Test results are most useful when interpreted together with symptoms and clinical history.

Some food allergies may change over time, but follow-up with a specialist is important before reintroducing any food.

If a food seems to cause reactions, it is safest to avoid it until a specialist can evaluate the situation.

A specialist visit is important when there has been a suspected reaction, recurring symptoms, or uncertainty about diagnosis.

Treatment and oral immunotherapy

These questions focus on oral immunotherapy, treatment goals, and how food allergy care is managed over time.

Q1. What is oral immunotherapy?

Oral immunotherapy is a treatment that uses gradually increasing doses of a food allergen to reduce immune reactivity over time.

No. OIT is not considered a cure, but it may reduce the risk of severe reactions from accidental exposure.

Many patients with confirmed IgE-mediated food allergy may be candidates, but treatment fit depends on diagnosis, safety factors, and treatment goals.

Depending on the patient and the program, OIT may be used for foods such as peanut, milk, egg, wheat, sesame, or selected tree nuts.

Treatment often progresses over months and may continue longer depending on the plan and patient response.

Yes. Reactions can still happen during treatment, which is why supervision and follow-up are important.

The goal is to raise the reaction threshold and reduce the risk from accidental exposure.

Anaphylaxis and emergency planning

These questions help families understand what to do if a reaction happens and why emergency planning matters.

Q1. What is anaphylaxis?

Anaphylaxis is a serious allergic reaction that can affect breathing, circulation, or multiple body systems at once.

No. Antihistamines may help with minor symptoms, but they do not treat a severe allergic reaction.

Epinephrine should be used immediately for a severe allergic reaction or suspected anaphylaxis.

Yes. Emergency medical evaluation is still important even if symptoms begin to improve.

Yes. A written food allergy and anaphylaxis action plan helps caregivers respond quickly and correctly.

Follow the treatment plan provided by your clinician and seek urgent care if symptoms worsen or seem more than mild.

Because food allergy reactions can escalate quickly, families, schools, and caregivers need a clear plan in advance.

School, activities, and everyday life

School, daycare, activities, and shared meals are common sources of stress for families managing food allergies.

Q1. What should schools know about my child’s food allergy?

Schools should understand the allergy, know where emergency medication is kept, and have a written emergency care plan.

Yes. Families should provide the prescribed emergency medication and clear instructions for its use.

Yes, with planning, communication, and a clear emergency plan in place.

Families and schools should discuss food use in class activities, snacks, celebrations, and shared surfaces.

Age-appropriate education, preparation, and self-advocacy skills can help children feel safer and more confident over time.

Yes. Food allergy bullying is a real concern and should be addressed proactively with school staff.

Yes. Specialists can help families understand diagnosis, safety planning, and what information schools should have.

Travel, restaurants, and eating away from home

Travel, restaurants, and social events create extra uncertainty, so families benefit from planning ahead and keeping routines simple.

Q1. How can we prepare for travel with food allergies?

Plan ahead, review meal options, pack safe foods when possible, and bring emergency medication.

Yes. Safe backup food can reduce uncertainty during travel or long outings.

Ask about ingredients, preparation methods, and cross-contact risk before ordering.

Ingredients can change, and labels remain one of the most important ways to avoid accidental exposure.

Yes. Everyone involved in meals, snacks, or child care should understand the allergy and know what to do in an emergency.

Yes. Clear communication, safe food planning, and preparation can make events easier to navigate.

When ingredients or preparation are unclear, it is usually safer not to eat the food.
