How does soy allergy affect the body?

A soy allergy is the result of an immune system problem. The body of a person affected with a soy allergy targets soy as harmful by producing antibodies that produce chemicals creating allergy symptoms. Symptoms of a soy allergy can affect several parts of the body, including the skin, airways, lips and mouth, and abdomen. Those who are not very allergic to soy will generally experience skin irritations a few minutes to a few hours after eating a soy product. People with more severe allergies will experience airway constriction and other serious symptoms. Usually, these severe reactions happen quickly, sometimes within minutes of eating just a tiny bit of a soy product.

If eating soy causes a severe reaction with serious symptoms, such as dropping blood pressure, weakened or rapid pulse, difficulty breathing or dizziness, you should go to the nearest emergency room. These are symptoms of anaphylactic shock, a serious reaction to soy that can be fatal. If you experience milder symptoms, you can schedule a doctor's appointment for diagnosis and treatment.
