Any person will never realize if he/she is allergic to a kind of food unless and until they have consumed the food allergen. For the reaction to happen and create a symptom it requires a certain quantity of food.
Anaphylaxis and allergy caused by food are related closely. A person could develop an allergic reaction to the food which is related closely to the original allergy that he/she has. An allergy, say, to oysters could lead to allergic reactions when a person takes fish, shrimp, or crabs.
When an individual has a food allergy, a person’s immune system tends to react 2 ways. The body may react to the use of mast cells or not. The mast cells can be found in any part of the body but it is most likely to be found in eyes, skin, lungs, and throat and especially in the areas of the gastrointestinal system. The other kind of response is by the release of immunoglobulin E by the body. These antibodies travel across the blood system. Then it causes the discharge of the chemical histamine which in turn causes the allergic reactions to activate in the body parts that were mentioned above. Anaphylaxis is the abrupt response for the allergy which is greater in degree stronger than the normal allergy that can be vital to the sufferer. An Allergy Testing Specialist Near Orland Park can help in treating this serious allergic reaction. The main causes of anaphylaxis are the latex which is in contact with the skin, insect stings, food anaphylaxis, and medications. There may be even unknown causes. Anaphylaxis involves the reaction, like in allergy caused by food, of different body parts. The main difference is that only a limited amount of allergen and intensity of the response is required for this reaction to happen.
Anaphylaxis could come about by the skin contact, inhalation of (food) aroma, food, etc. anaphylactic shock is the type of anaphylaxis which is life-threatening. Only a meager amount of allergen is required to cause death to the person within a few minutes of exposure in anaphylactic shock. People who have a bad history of allergy to asthma, eczema, and food are the ones who are in danger of getting this anaphylactic reaction. These reactions are fatally creating a sense of fear. Another group of individuals who are at risk of anaphylaxis is teenagers who are affected by a certain kind of food allergy present, especially in junk foods. This because these teenagers tend to eat outside very often, are experimental, and daring in their new endeavors and so they fail to find the symptoms of this dangerous reaction.

Symptoms of anaphylaxis usually start within minutes to an hour or so after a trigger is exposed. The most common symptoms of anaphylaxis are hives and swelling of the skin, which occur in most cases. Respiratory symptoms often occur and are particularly common in people who also have asthma or other chronic respiratory illness. Extremely low blood pressure also occurs commonly causing lightheadedness, dizziness, blurred vision, or loss of consciousness (passing out).

This form of anaphylaxis most commonly occurs after a person is administered a medication into a vein or stung by an insect. Up to 20% of people with anaphylaxis have biphasic anaphylaxis, in which symptoms resolve and then recur without further exposure to the trigger. This can happen after the initial symptoms, several hours after. Rarely, despite treatment anaphylaxis can be prolonged and last for hours or several days.
