Food Allergy Q & A

Why do some people have food allergies?

When your immune system has an irregular response to normally safe substances, it’s an allergy. Foods can cause such responses in your immune system, resulting in an allergic reaction. 

Technically, you can develop an allergy to any food, any time in your life. But, food allergies are most common in children. Sometimes these allergies go away as a child gets older, but some allergies can persist through adulthood.

Food allergies are more common than many people realize and most often occur due to consumption of: 

  • Milk
  • Peanuts
  • Eggs 
  • Tree nuts
  • Soy
  • Wheat
  • Fish
  • Shellfish

What symptoms suggest a food allergy?

Symptoms of a food allergy may appear on the skin, gastrointestinal tract, or respiratory system. 

Symptoms usually appear within 30-60 minutes of consuming an offending food. Occasionally, symptoms can show up hours or days later. 

Symptoms of a food allergy include:

  • Itchy and/or swollen tongue or throat
  • Abdominal pain
  • Diarrhea
  • Vomiting
  • Coughing
  • Wheezing
  • Trouble breathing
  • Drop in blood pressure
  • Dizziness
  • Eczema

Severe food allergies can result in an anaphylactic reaction. This life-threatening condition can close off your airway, causing extreme shortness of breath, low blood pressure, and loss of consciousness. Anaphylaxis requires immediate emergency treatment. 

What methods can diagnose food allergies?

Food allergies may require some detective work to identify. Dr. Williams may ask you to keep a food diary for several days to identify a trigger. If you have an idea of what is causing your allergic reaction, she will perform a skin prick test or blood test to determine what is causing your allergies. 

What is the best treatment for food allergies?

The best way to treat a food allergy is to eliminate the offending food from your diet. Dr. Williams can help you identify hidden sources of your specific allergen and learn how to read food labels. 

If you have a severe food allergy that puts you at risk of anaphylaxis, Dr. Williams provides you with an epinephrine pen in case you do accidentally come in contact with the allergen.
