Food Allergies

What are Food Allergies?


A food allergy is a dangerous immune response triggered by foods that cause an allergic reaction or anaphylaxis. Very few people have a real food allergy, most have a food intolerance. Common food allergies include peanuts, milk, eggs, tree nuts, fish, shellfish (crab, lobster, shrimp), wheat and soy.

SYMPTOMS

Food allergy reactions range in severity from mild symptoms to a severe, life-threatening reaction known as anaphylaxis.

Symptoms may include:

Itching, hives, eczema flare

Swelling of the face, lips, throat, tongue or other parts of the body

Breathing problems such as wheezing, coughing, shortness of breath

Gastrointestinal symptoms such as vomiting, diarrhea, abdominal pain/cramping

Light headedness, fainting, drop in blood pressure

Feeling that something bad is about to happen

TREATMENTS

The first step in managing food allergy is to correctly identify food allergens. Ask your allergist about food allergy testing. There are several types of food allergy tests including skin tests, blood tests (also known as RAST) and patch tests. Your doctor will help to decide which test will be most appropriate for you.

Currently, there is no cure for food allergies, although researchers are studying new ways to treat food allergy. At present, our best strategies are avoidance and prompt treatment of any accidental exposures.

Talk to your allergist about available emergency medications:

Injectable epinephrine (such as EpiPen, Auvi-Q, Adrenaclick)

Antihistamines

In some cases, steroids (oral, intramuscular or IV)
