Food allergy symptoms vary widely and are different in severity from person to person. Those less allergic to certain foods may find their food allergy symptoms simply annoying, but those with severe food allergies will need to avoid the offending food entirely. Severe allergic reactions can be life threatening.
Some more common food allergy symptoms are listed below.
* Eczema and other skin conditions from hives to mysterious rashes.
* Nausea, vomiting and diarrhea
* Runny nose, sneezing
* Shortness of breath
In anaphylaxis, the heart's blood pumping ability is compromised, resulting in low blood pressure or unconsciousness. Those at risk for anaphylaxis should carry an Epi Pen with them at all times. In the event they are exposed to the allergen, the Epi Pen would administer a dose of adrenaline, reversing the reaction.
