TYPES OF ALLERGIES

In an allergy attack, the symptoms experienced depend on where in the body histamine is released. Allergic reactions to foods most often involve the skin, the stomach and intestines (digestive tract), and the mouth and airways (respiratory system). A life-threatening reaction may involve all parts of the body including the cardiovascular system so that the individual goes into shock (the blood pressure falls dangerously low). A severe reaction could start very suddenly and involve only a fall in blood pressure (shock). It is important to know that a life-threatening reaction may occur with no skin symptoms.

Symptoms may appear within minutes or as long as several hours after eating the allergy-provoking food.
