What are the symptoms of soy allergies?

Dr. Jeanne Morrison, PhD
Family Practitioner

With a soy allergy, the immune system releases a chemical called histamine, which leads to traditional symptoms of allergic reactions, such as runny nose, itchy eyes and rashes or hives. Other common symptoms may include wheezing, diarrhea, nausea and dizziness. Although most symptoms of soy allergy are mild, it can also result in anaphylactic shock, which can be serious and even deadly. Anaphylactic shock, which is more likely in people with asthma and other conditions, can create airway swelling, a drop in blood pressure and loss of consciousness.

If you're experiencing symptoms of a soy allergy, you should visit a doctor or allergy specialist. It is best to make this visit while the allergic reaction is occurring. That way, your doctor will better understand and analyze your symptoms and can make recommendations for the most effective treatment. However, if you or your child experiences serious symptoms of a soy allergy, such as airway constriction or loss of consciousness, you should call 911 or go to an emergency room right away.
