Important Facts You Should Know about Food Allergy

Some allergic reactions on the other hand can be serious and deadly but they can be arrested if someone is quick enough to administer emergency relief such as epinephrine or take the sufferer to an allergy doctor immediately for treatment.


Who are potential sufferers of food allergy?


Genetics play a big role in the allergy story. If one or both your parents have food allergies, you are more likely to have it too.


Food allergies are common in children, but many of them outgrow the disorder as their bodies learn to adapt to the triggers over time. People who develop the disorder as adults may have it for the rest of their lives.


Many people make a mistake of taking food intolerance as allergy. These two can have similar symptoms but they are two different things that are treated in different ways. Food intolerance refers to the body’s inability to process certain foods. It can cause some discomfort but it is not life-threatening. Food allergy on the other hand, refers to the reaction of the immune system to certain foods that you eat. It can be dangerous when it becomes too severe especially when anaphylaxis takes place.

Food allergy can trigger a lot of symptoms. If you eat certain foods and your immune system mistakes them as a threat, these symptoms are likely to appear:


Tingling sensation in the mouth

Swelling of the lips

Stomach upset or stomach cramps



Dropping of blood pressure

Appearance of hives or skin rashes


Food allergy usually manifests the same symptoms in both children and adults. But for some children who are allergic to milk or soya, symptoms can include eczema, diarrhea, vomiting, bloody stool and constipation.




When an allergy becomes severe, anaphylaxis can happen which can be life-threatening. This condition can take place within minutes to a few hours after a person eats certain foods he or she is allergic to. Some of the known triggers of anaphylaxis include peanuts and sea foods like shrimp, squid and shellfish. Exercise, alcohol and aspirin are also possible triggers of severe allergic reactions.
