A food allergy happens when the body’s immune system responds abnormally to certain foods. Most reactions are less serious, but some can be serious. In rare cases, a person may experience a serious allergic reaction called anaphylaxis, which can be life-threatening.

types of food allergies

What are the types of food allergies?

Food allergies are generally divided into three categories. That include:

diagnosis

How are food allergies diagnosed?

Food allergies are diagnosed through a combination of medical history, physical examination, and specific food allergy tests. Here’s how doctors typically identify food allergies:

Detailed physical examination

Your doctor will check for possible allergy symptoms like swelling, redness, breathing difficulties, and others. You may be asked questions on what you might be allergic to and what was consumed.

Skin Prick Test

In this food allergy test, a small amount of the suspected allergen is placed on your skin, usually on the forearm. The skin is then gently pricked or scratched so the substance can enter the surface. If you’re allergic, a red, itchy bump—similar to a mosquito bite—will usually show up within 15 to 20 minutes.

Blood tests

Food allergy blood test checks for certain allergy-related antibodies in your blood. They help find out which specific substances might be causing your allergic reactions.

Oral food challenge

This test involves eating small amounts of the food that might be causing an allergy, while being closely watched by a doctor. It’s the most reliable way to find out if you have a food allergy, but it’s done in a medical setting because there’s a chance of a serious reaction.
