Symptoms Of A Food Allergy

During an allergy attack, symptoms may vary based upon where histamine is released in the body. Allergic reactions can be as simple as a sneeze or an upset stomach, but they can also be as terrifying as anaphylactic shock.


Digestive Symptoms


Stomach pain, nausea, vomiting and diarrhea can all be symptoms of an allergic reaction.








Skin Symptoms


Hives and eczema can appear on the skin, along with swelling of the lips or throat, mere moments after a food is eaten.


Respiratory Symptoms


Some food allergies may manifest simply by provoking sneezing or coughing, but severe reactions can result in anaphylaxis (breathing difficulties resulting from the closing of the throat).


Other Symptoms


Food allergies may also cause lightheadedness, dizziness or, in extreme cases, a loss of consciousness.


Exercise-Induced Food Allergies


As the body becomes physically stimulated, a person can become itchy or lightheaded. Hives and even anaphylaxis can occur. Such a condition can be prevented by avoiding food for up to two hours before exercise.


Fruit and Vegetable Allergies


Certain fruits and vegetables can cause a cross-reactive allergy. Proteins in certain foods can provoke a reaction if one is allergic to the pollens similar to them. Cooking foods can alleviate these allergies.


Treat a Food Allergy


If an allergic reaction is not serious, it can be treated with an over-the-counter antihistamine product such as Benadryl. However, if a person suffers from breathing difficulties, hives or severe swelling around the mouth or eyes, medical attention is needed. The use of an epinephrine syringe (commonly known as an Epi-Pen) can often delay the onset of anaphylaxis. An anaphylactic allergic reaction can be fatal if not treated as quickly as possible.
