What is a Food Allergy?

  • Is an abnormal immune reaction when a certain food has been eaten.

When triggered, you may experience:

  • itchiness
  • swelling of the tongue
  • Swollen airways
  • vomiting
  • lips tingling 
  • diarrhea
  • hives 
  • trouble breathing, 
  • digestive problems
  • low blood pressure

What are the factors?


The most common food allergies are cow’s milk, eggs, tree nuts (walnuts & pecans), peanuts, shellfish, fish, soy and wheat.

Who’s at risk?

This is an allergy that can, unfortunately, adapt during one’s childhood and is commonly known in children. In some cases, the food allergy can resolve during adulthood, but primarily the cause of food allergies is unknown. There are treatments to help cope with symptoms but no known cure to get rid of the allergies for good. If you have a family history of asthma, eczema, hives, or hay fever allergies you are likely to be at risk.

How is it diagnosed?

This can be diagnosed by several specialists known as an Allergist, Gastroenterologist, Immunologist, Nutritionist, and Pediatrician confirmed by testing such as a blood test or a skin test. 

What are common treatments, diet, and lifestyle recommendations?

Food Allergies are treated with antihistamines, such as Benadryl, or in severe cases, you will then need an injection of the drug epinephrine, also known as an epi-pen. Most commonly once you receive test results you will be recommended to avoid the allergic foods at any cause to prevent an outbreak. 

These signs and symptoms could signal an underlying digestive condition. Intestinal symptoms can be embarrassing — but don’t let embarrassment keep you from seeking help.
