What are the signs and symptoms of a soya allergy?

The signs and symptoms a soya allergy are those of any other food allergy. This includes hives on the skin, swelling of the face, lips, tongue, and throat (which may cause difficulty in breathing), abdominal pain, diarrhoea, vomiting, wheezing, a runny or blocked nose, or a rash with itching. These symptoms can occur immediately, but can also occur days after you have eaten soya.

A life threatening condition known as anaphylaxis may develop in some people very soon after they have eaten soya proteins. During anaphylaxis, all the blood vessels in your body become very wide, so your blood pressure drops to dangerous lows. Your airways can also tighten, meaning you might not be able to get enough air in. Signs and symptoms of an anaphylactic shock includes sweating, anxiety or terror, a very fast heart rate, a low blood pressure, and difficulty in breathing. Anaphylaxis requires urgent treatment with adrenaline, usually given by an EpiPen.
