A food allergy results in the bodies immune system attacking an item of food that it mistakes for an invader. Symptoms vary from person to person, but often result in tingling around the lips and on the tongue, swelling in the mouth and nose, trouble breathing and nausea. In severe cases this can lead to anaphylaxis, where the bodies pulse rate increases, breathing becomes more difficult and nausea and diarrhoea can be accompanied by unconsciousness. The most common allergens are peanuts, shell fish and celery but any food can result in an allergy. These allergies are linked closely with chronic conditions such as asthma, eczema and hay fever. The allergen can often be discovered using a skin prick test at your local GP surgery, introducing a small amount of the allergen to the body. Though food allergies are not curable, eliminating the food from ones diet should prevent symptoms from developing and an adrenaline injector pen can be carried for use in emergencies.
