A food allergy is an immune-mediated adverse reaction to a particular food.
For someone with a food allergy, eating or swallowing even a tiny amount of a particular food can cause symptoms such as: skin rash, nausea, vomiting, cramping, and diarrhea. Because the body is reacting to something that is otherwise harmless, this type of allergic reaction is often called a hypersensitivity reaction. Rarely, a severe allergic reaction can cause a life-threatening set of symptoms called anaphylaxis, or anaphylactic shock.
It is easy to confuse food intolerance with food allergy because they can have similar symptoms. With food intolerance, however, a person usually gets only mild symptoms such as an upset stomach.
Food Allergy Diagnosis
Generally a food allergy is identified by signs and symptoms. Medical professionals are trained to recognize hives, swelling patterns, rashes, and other symptoms associated with allergic reactions. The person will be asked questions about their medical history and possible triggers of the reaction. Blood tests and other tests are needed only under very unusual circumstances, such as anaphylaxis.
Some people can pinpoint which food caused the allergic reaction, especially if the reaction occurs within minutes of consuming a particular food. Many others will need to see an allergist for special testing to determine the exact food that is responsible.
After getting advice from the health care professional, some mild allergic reactions may be treated at home. Any worsening of symptoms requires medical attention.
